1–2 INTRODUCTION Troxler, the leader in density gauge technology, now offers the Model 2701-B PaveTracker Plus (see Figure 1–1), an electromagnetic sensing device that quickly gives an indication of the density of asphalt pavement. The advanced technology in the patented PaveTracker Plus allows rapid and reliable measurements. The PaveTracker Plus can be used on existing asphalt pavements or on freshly placed mats. The unit is ideal for performing quick quality control measurements to check for segregation, areas of low density, and overall pavement uniformity. The PaveTracker Plus is a precision device that is designed to provide many years of trouble-free service. As any precision device, the PaveTracker Plus requires reasonable care and maintenance to ensure its accuracy and reliability. The user should: ♦ Keep the unit clean and free of all road debris. ♦ Return the unit to Troxler for yearly re-calibration and inspection. ♦ Ensure that the unit remains sealed at all times. There are no field-serviceable components inside the unit. Opening the case will affect the integrity of the unit and therefore will void the warranty.

1–4 FEATURES The PaveTracker Plus (see Figure 1–1) incorporates a number of features that provide unmatched efficiency, usability, and flexibility. The PaveTracker Plus takes density measurements using electromagnetic sensing technology, eliminating the need for government licenses or special training. Measurements are completed within 2 seconds, saving time and money. The unit’s memory can store approximately 1000 readings for later viewing, printing, or downloading. Both the 30-button keypad and 4 x 20 liquid crystal display (LCD) screen are backlit, making them easy to see, day or night. The gauge includes a replaceable protective cover on its bottom surface. The protective cover provides thermal protection for the gauge’s internal components and protects the bottom surface of the gauge against wear. The carrying case for the Model 2701-B includes a built-in reference standard, which provides a density measurement standard for taking reference readings. The PaveTracker Plus’s advanced software provides three test modes (continuous, averaging, and segregation) for greater flexibility and multiple applications. The software also provides automatic calculations (average density, percent maximum density, percent air voids, and so on) for greater ease of use. Gauge measurements can be adjusted using a density offset, slope adjust, or mix calibration to increase accuracy on specific materials. Both an ac charger and a dc adapter are included with the PaveTracker Plus, enabling the unit to be recharged from an ac outlet or a 12 V dc system.

Model 2701-B 1–5 1. INTRODUCTION The gauge features two audible indicators, an internally mounted beeper, as well as a louder, external one mounted on its underside. The internal beeper emits a short tone in response to a valid keystroke on the keypad. It sounds a longer tone when the operator presses an invalid key or if the gauge displays an error message. The external beeper performs the same functions, and can be enabled or disabled as desired by the operator. A serial communications port is mounted on the front of the gauge. The serial port is used to output data to a serial device, such as a computer or printer. The detachable telescoping handle reduces bending for gauge operations. A second carrying handle is provided for ease of transporting the gauge.

1–6 GAUGE PARTS AND ACCESSORIES 1. The gauge is the portable electromagnetic sensing device containing all electronic modules and a rechargeable battery pack. 2. The carrying case for the Model 2701-B includes a built-in reference standard, which provides a density measurement standard for taking reference readings. 3. The ac charger and dc adapter are used to charge the gauge batteries. The ac charger accepts 100 – 240 V ac, 47 – 63 Hz and supplies 12 V dc at 1.8 A. The dc adapter allows recharging from a 12 V dc system, such as a vehicle cigarette lighter. 4. The manual (not shown) details how to operate and maintain the gauge. 5. A printer (optional, not shown) connects to the gauge for printing data.

2–14 TARGET The Model 2701-B can store up to four Gmb (Marshall) and four Gmm (Voidless density) target values. A Gmb value is the bulk density of a material, often determined using the Marshall method. A Gmm value is the maximum theoretical density for a test material as obtained in laboratory tests. The gauge uses target values to determine the percent compaction and/or percent voids (if a Gmm value is entered) as compared to the measured density of the test material. With the Target function, the operator can enter a new target value, enable a stored target value, or disable a target value. To access the Target function, press the ⟨TARGET⟩ key. The gauge displays the Target menu: -Target- 1. Gmb(Marshall) 2. Gmm(Voidless) Press # to Select To enter, enable, or disable a Gmb (Marshall) or Gmm (Voidless density) value, press the corresponding numeric key. For example, to edit the Gmb (Marshall) value, press ⟨1⟩. The gauge displays the Gmb(MA) Value: menu shown below. The Gmm(Void) Value: menu is similar and operates in the same manner. Gmb(MA) Value: 1. #.# 2. #.# 3. #.# 4. #.# 5. New 6. Disable The target value menu shows the four stored target values (if any) and the New and Disable options. ENABLE A TARGET VALUE To enable a displayed target value, press the corresponding numeric key on the target value menu. The gauge enables the target value and returns to the Ready screen.

The gauge displays: Gmb(Marshall) Value: 0.0 pcf Press <ENTER> Use the numeric and decimal keys to enter the target value. Press the ⟨ENTER/START⟩ key. The gauge displays: Gmb(MA) = ##.# Do You Want to Save This Value for Late Use? To store the value, press the ⟨YES⟩ key. To use the value now without storing it for later use, press the ⟨NO⟩ key. If the operator presses the ⟨YES⟩ key to store the target value, the gauge displays: Select Memory Cell 1. #.# 2. #.# 3. #.# 4. #.# Press # To Select The gauge can store the target value in one of four memory cells. Use the numeric keys to store the target value. Note that this will replace any target value that was previously stored in the memory cell. The gauge enables the target value, displays a brief confirmation message and returns to the Ready screen. DISABLE THE TARGET VALUE To disable the current target value, press ⟨6⟩ at the target value menu. The gauge disables the target value, displays a brief confirmation message, and returns to the Ready screen.

2–16 MODE The Model 2701-B provides three measurement modes: ♦ In continuous mode, the gauge takes a measurement and updates the display every second. This mode is used for typical quality control measurements. ♦ In averaging mode, the operator can take up to 30 measurements at selected locations. The gauge then calculates the average of the measurements. This mode enables the operator to determine the average density over a selected area. The Store function (see page 5–9) records the most recent results screen when in this mode. ♦ In segregation mode, the operator can take up to 30 measurements at selected locations. The gauge then displays the high, low, and average density of the readings. This mode enables the operator to determine the degree of segregation in the area being measured. The Store function (see page 5–9) records the most recent results screen when in this mode. Before taking a measurement, select the appropriate measurement mode. To select a measurement mode, press the ⟨MODE⟩ key. The gauge displays: -MODE- 1. Continuous 2. Averaging 3. Segregation Press the numeric key that corresponds to the desired measurement mode. The gauge enables the selected mode, displays a brief confirmation message, and returns to the Ready display.

3–2 INTRODUCTION As described on page 4–2, Troxler recommends taking a reference reading each day that the gauge will be used, and periodically while taking measurements. The reference reading consists of placing the gauge on the reference standard contained in the gauge carrying case and pressing the ⟨Ref⟩ key. The density read by the gauge is then compared to the known density of the reference standard. The result of this comparison is used to automatically adjust gauge measurements. For increased accuracy, measurements can be adjusted using density offset and slope adjust values described in the following sections. To determine the density offset, take a gauge reading and compare the measured value to the actual density, as measured by an alternate method (such as using a nuclear gauge or extraction and analysis of a road core). A density offset can also be determined using a gyratory-compacted specimen. For a given material, the density offset and slope adjust values can also be determined using the Mix Calibration function described on page 3–7. The Slope Adjust function enables the operator to enter the slope value manually.

Model 2701-B 3–3 3. ADJUSTING MEASUREMENTSOFFSET To improve the accuracy of the PaveTracker for a specific material of known density, the unit can be calibrated using a density offset. A density offset can be determined from in-place measurements or from 150-mm gyratory-compacted samples. DETERMINING THE DENSITY OFFSET To determine the density offset for a given material: 1. Take a reference reading using the PaveTracker Plus as described on page 4–2. 2. Determine the actual density of the material using a nuclear gauge reading, road core extraction and analysis, or laboratory analysis of a gyratory-compacted sample. If using a nuclear gauge to make an in-place measurement, mark the test site so that PaveTracker Plus readings can be taken in the same location. 3. Using the PaveTracker Plus, determine the measured density as follows:  If offsetting the PaveTracker Plus to a nuclear gauge reading or a core analysis, measure the in-place density of the material using the PaveTracker Plus. Be sure to take the measurements in the same location as the nuclear gauge reading or as close as possible to the core location (on the site, if the core has not yet been removed).  If using a gyratory-compacted sample, set the PaveTracker Plus up as follows: a. As shown in Figure 3–1, place two samples of the same height approximately 4.75 inches (12 cm) apart. Place a mark on the sample as shown in the figure. b. Place the PaveTracker Plus on the samples. Ensure that the circular sensor on the bottom of the PaveTracker Plus is centered on the sample to be measured. c. Measure and record the density of the sample.

Repeat steps b through d until at least three measurements have been taken. f. Average the measured values to determine the measured density. 4. Subtract the actual density from the measured density to determine the density offset. NOTE For best results, repeat the above procedure to determine the density offset at each of several in-place locations or for each of several gyratory-compacted samples. Then calculate the average density offset.

Model 2701-B 3–7 3. ADJUSTING MEASUREMENTSMIX CALIBRATION As noted earlier, the PaveTracker Plus can be calibrated for a specific mix using the Mix Calibration function. To use this function, the operator takes gauge measurements at three to ten locations across the material. The gauge compares these values to values obtained by core analysis or another method to determine a slope and density offset for that particular material. The gauge can store up to four mix calibrations. NOTE In order for the gauge to calculate both a slope and an offset for the test material, measurements must be performed at a minimum of three locations. Also, the difference between the minimum and maximum reading must be at least 3 pcf. For best results, Troxler recommends taking measurements at seven to ten locations. To access the Mix Calibration function, press ⟨8⟩ on the Setup menu shown on page 2–7. The gauge displays: 1. 2. 3. 4. 5. New 6. Disable 7. View Selections 1 through 4 show the mix calibrations that have been stored previously. Use the numeric keys to enable an existing mix calibration, create a new calibration, disable an active calibration, or view a calibration. ENABLE A MIX CALIBRATION To enable a displayed mix calibration, press the corresponding numeric key. The gauge enables the mix calibration and returns to the Ready screen. Note that, because the mix calibration includes a slope adjust value, the symbol / is displayed on the top line of the Ready screen.

3–8 DETERMINING A NEW MIX CALIBRATION Before performing a mix calibration, press the ⟨STATUS⟩ key from the Ready screen. The gauge displays gauge status information as described on page 2–6. Press the down arrow to display the second screen and record the Last Ref value. After recording the Last Ref value, take density measurements using the gauge and an alternate method as described below: 1. Prepare the sample area for testing as described on page 4–4. 2. Take a gauge measurement at each marked location as described on page 4–5 and record the measured value. As noted earlier, in order for the gauge to calculate both a slope and an offset, measurements must be performed at a minimum of three locations. The difference between the minimum and maximum reading must be at least 3 pcf. For increased accuracy, Troxler recommends taking measurements at between seven to ten locations. 3. Take a density measurement at each location using an alternate method, such as a nuclear gauge or by core extraction and analysis. To determine a new mix calibration, press ⟨8⟩ on the Setup menu shown on page 2–7 to access the Mix Calibration function. Then press ⟨5⟩.

Model 2701-B 4–1 4. USING THE GAUGE CHAPTER 4 USING THE GAUGE This chapter explains the basic use of the Model 2701-B PaveTracker Plus. Basic use includes taking the daily standard count, preparing measurement sites, setting the measurement mode, and taking measurements. CONTENTS Taking a Reference Reading......................................................... 4–2 Preparing a Test Site..................................................................... 4–4 Taking Measurements................................................................... 4–5 Continuous Mode................................................................... 4–5 Averaging Mode..................................................................... 4–6 Segregation Mode .................................................................. 4–8 Recall.......................................................................................... 4–11

4–2 TAKING A REFERENCE READING To ensure the accuracy of gauge measurements, Troxler recommends that a reference reading be taken each time the gauge is powered on, and periodically while taking measurements. A reference reading consists of taking a density measurement on a material of known density. The gauge then compares the reading to the known value and uses the result of that comparison to adjust future gauge readings. NOTE A reference standard, built into the gauge carrying case, is provided for this purpose. Always take reference readings using the reference standard in the carrying case provided with the specific unit. Turn the gauge on as described on page 2–4. At the Ready screen, press the ⟨REF⟩ key. The gauge displays: Place Gauge on Reference Standard (Carrying Case) Press <START> Place the gauge on the reference standard (in the carrying case). Ensure that the circular sensor on the bottom of the gauge is centered between the four locating pins inside the case, and that the sensor rests flat against the surface. Press the ⟨ENTER/START⟩ key to begin the reference reading. Upon completion, the gauge displays: Reference Reading Complete Press <ENTER> Press the ⟨ENTER/START⟩ key to continue. The gauge stores the result of the reading and returns to the Ready screen. The result is then used to adjust all gauge readings.

Model 2701-B 4–3 4. USING THE GAUGENOTE If the reference reading is out of range and the gauge displays an error message, check the following: ♦ Ensure that the circular sensor cover is firmly in place on the gauge sensor (press firmly around the perimeter of the cover). ♦ Ensure that the cover and reference standard are totally clean and free of any asphalt residue, moisture, or debris. Clean with WD-40 or other suitable means. ♦ Ensure that the sensor cover is seated flat and flush on the reference standard, within the four locating pins, with the gauge in the case. Repeat the reference reading. If the reference reading still does not pass, contact Troxler technical support (see page A–9). To verify that the gauge is still accurate during use, perform the following check: ♦ Ensure that the gauge is turned on and in measurement mode. ♦ Turn off (disable) all operator-installed density offsets, slope adjust values, and mix calibrations. See Chapter 3 for specifics. ♦ Place the gauge on the reference standard and verify that it reads within ± 0.5 pcf of the actual density value stamped on the reference standard. If the reading is outside these limits, take a reference reading as described in this section to adjust the gauge. Note that each reference standard is unique to that individual gauge. Use care to not intermix different gauges and cases.

4–4 PREPARING A TEST SITE To ensure measurement accuracy, properly prepare the test site before taking gauge measurements.  Locate a smooth site on the asphalt.  To ensure accurate readings, the gauge sensor must be completely in contact with the test material. If the gauge rocks, then find a more suitable test site. If taking a measurement around a core, the gauge may be moved a few inches away from the core to level it.

Model 2701-B 4–5 4. USING THE GAUGE TAKING MEASUREMENTS The Status feature (see page 2–6) allows the operator to view the current gauge status. This feature provides a quick overview of the battery voltage, internal temperature, selected measurement units, and the date and time of the last reference reading. If necessary, check the gauge’s current status before taking measurements. NOTE To ensure the accuracy of gauge measurements, take a reference reading each day the gauge is to be used (see page 4–2) and periodically while taking measurements. As described on page 2–16, the PaveTracker Plus provides three measurement modes: continuous, averaging, and segregation. Before taking a measurement, select the appropriate measurement mode. CAUTION The gauge includes a replaceable protective cover that protects the bottom surface of the gauge’s sensor assembly against wear and provides thermal protection for the gauge’s internal components. To prevent damage to the gauge, DO NOT operate the gauge without the protective cover. CONTINUOUS MODE In continuous mode, the gauge takes a measurement and updates the display every second. This mode is used for typical quality control measurements. Extend the telescoping handle (see Figure 1–1) to reduce the bending required while taking measurements. To take a measurement in continuous mode, select the mode as described on page 2–16. Place the gauge on the test site and press ⟨ENTER/START⟩.

4–6 The gauge displays the measurement results, updated every second, as shown: ##.#% Gmb(MA) ##.#% Gmm(Voidless) D: ###.# ##.#% Voids <ESC> NOTE If the Temperature option (see page 2–10) is installed, the mat temperature is also shown in the upper right corner of the display. Press ⟨ESC⟩ to return to the Ready screen. For more information on storing measured data, see the Storing Data section on page 5–7. NOTE If the gauge goes into sleep mode while in the continuous measurement mode (see page 2–16), the display returns to the Ready screen. To exit sleep mode and continue taking measurements, press the ⟨ENTER/START⟩ key. AVERAGING MODE In averaging mode, the operator can take up to 30 measurements at selected locations. The gauge then calculates the average of the measurements. This mode enables the operator to determine the average density over a larger area. Extend the telescoping handle (see Figure 1–1) to reduce the bending required while taking measurements. To take a measurement in averaging mode, select the mode as described on page 2–16.

Press ⟨ENTER/START⟩ to continue. Repeat the steps above to take a measurement at up to 30 test locations. When all locations are complete, press the ⟨STORE⟩ or ⟨ESC⟩ key to continue. If the ⟨ESC⟩ key is pressed, the gauge displays: End of Measurement Do You Want To Store ? <YES> or <NO> Press ⟨NO⟩ to return to the Ready screen without storing the results or ⟨YES⟩ to continue as described below.

4–8 If the ⟨STORE⟩ key is pressed at the end of the measurements (or if the operator presses ⟨ESC⟩ then ⟨YES⟩), the gauge displays: Do You Want To Add Notes? <YES> or <NO> When storing test results, the gauge can also store project notes, such as location information, with the measurement data. To include project notes, press ⟨YES⟩. The gauge displays: Input Location Press <ENTER> Enter any desired information (up to eight characters) and press ⟨ENTER/START⟩. The gauge stores the last displayed results and notes under the active project and returns to the Ready screen. For more information on storing measured data, see the Storing Data section on page 5–7. NOTE The gauge stores only the data shown in the last display. It does not store the results of each individual reading. SEGREGATION MODE In segregation mode, the operator can take up to 30 measurements at selected locations. The gauge then displays the high, low, and average density of the readings. This mode enables the operator to determine if there is a large degree of segregation in the area being measured. Extend the telescoping handle (see Figure 1–1) to reduce the bending required while taking measurements.

Model 2701-B 4–9 4. USING THE GAUGE To take a measurement in segregation mode, select the mode as described on page 2–16. Press the ⟨ENTER/START⟩ key. The gauge displays: Segregation Mode Reading #: 1 Press <START> <STORE>/<ESC> to End Place the gauge on the first test site and press ⟨ENTER/START⟩.

Appendix A–2 TROUBLESHOOTING GAUGE WILL NOT COMMUNICATE WITH PRINTER OR COMPUTER  Check that the correct cable is being used.  Ensure that the printer/computer baud rate is 9,600 bps.  Ensure that all other parameters match: ♦ Data bits = 8 ♦ Stop bits = 2 ♦ Parity = none ♦ Protocol = DSR/DTR GAUGE TURNS OFF AFTER IT IS TURNED ON  To conserve power, the gauge provides an automatic shutdown if no key is pressed for 60 minutes. To turn the gauge on, press the power switch.  If the rechargeable NiMH battery pack is below 5.5 V dc, the gauge shuts down. Recharge or replace the batteries (see page A–3). SHORT BATTERY LIFE AFTER RECHARGING  NiMH batteries may be charged up to 500 or more full charge/discharge cycles, and typically have a 4-year life. The batteries may be reaching the end of their life cycle, and should be replaced.  Charger/adapter may not be supplying full charge – check the ac outlet and the dc output (12 V dc) using a voltmeter on the proper setting.  Check that you are using the correct charger.  The ac charger may be defective. To check, use the dc adapter to charge the batteries.

Model 2701-B Appendix A–3 A. TROUBLESHOOTING BATTERIES The PaveTracker Plus is equipped with one set of rechargeable nickel-metal hydride (NiMH) batteries (pack of five C batteries). The gauge software monitors the NiMH battery voltage. When the batteries are fully charged, the battery voltage should be between 6.8 and 7.2 V dc. If the voltage falls below 6.0 V dc, the gauge displays a low battery symbol () in the upper right of the Ready screen. Recharge the batteries as described below. If the voltage falls below 5.5 V dc, the gauge powers down automatically after completing any memory store functions already in progress. Troxler recommends that the operator recharge the NiMH batteries. The NiMH batteries can be fully recharged in only 2.5 hours. CHARGING To charge the NiMH batteries, plug the charger into the round jack on the front of the gauge. Plug the other end of the ac charger into a standard 100–240 V ac outlet. The dc adapter may be connected to any 12-14 V dc source (such as a vehicle's cigarette lighter). To ensure a full charge, charge the batteries for at least 2.5 hours. After charging, the battery voltage should be between 6.8 and 7.2 V dc. After recharging the batteries, unplug the charger from both the wall outlet and the gauge. Store the charger for later use.

Appendix A–4 REPLACING THE BATTERIES To replace the NiMH battery pack (PN 110374):  Turn the gauge off.  Using a 1/8-inch Allen wrench, remove the two screws that secure the battery cover to the base of the unit.  Clean the screws and set them aside.  Carefully lift the old NiMH battery pack from the gauge.  Unplug the battery cable from the battery connection on the top circuit board. Gently squeeze the connector to disconnect.  Plug the battery cable for the new NiMH battery pack into the battery connection on the top circuit board.  Slide the battery pack into the gauge.  Replace the battery cover and replace the two screws.

Model 2701-B Appendix A–5 A. TROUBLESHOOTING CLEANING THE BASE AND TOP SHELL To clean the gauge base, use a putty knife to scrape away any built-up accumulations of soil or asphalt. Be careful not to damage the gauge base! After removing any large accumulations, wipe the gauge base with a cloth soaked in WD-40® (see note below). The WD-40 should remove the remaining debris. CAUTION WD-40 can damage the keypad. Do not allow WD-40 to come in contact with the keypad! The keypad may be cleaned using a mild soap (such as 409™ or Fantastic™), followed by clean water. The 2701-B gauge top shell is manufactured from an engineering thermoplastic designed specifically to provide high impact strength and to offer excellent compatibility with many industrial solvents and petro-chemicals. The top shell may be cleaned with mild (low alkaline) soap and water. Other approved cleaning substances include: methyl, isopropyl, or isobutyl alcohols. A cloth dampened with kerosene or diesel fuel may be used to remove heavy soils. Avoid prolonged exposure and do not soak. CAUTION The use of any unapproved cleaning agents such as methyl-ethyl-ketones, amines, and methylene chloride will damage the top shell and void the warranty.

Appendix A–6 REPLACING THE PROTECTIVE COVER The gauge includes a replaceable protective cover (PN 113073) that protects the bottom surface of the gauge’s sensor assembly against wear and provides thermal protection for the gauge’s internal components. The protective cover snaps into place over the rear base assembly. When this cover becomes worn, it should be replaced as described below. CAUTION To prevent damage to the gauge, DO NOT operate the gauge without the protective cover. To remove the old protective cover:  Turn the gauge over so that its bottom surface is exposed. To prevent damage to the keypad or display, place the gauge on a soft surface.  Using both hands, place fingers beneath the rim of the old protective cover on one side. Press down on the flat surface of the cover with your thumbs while prying and lifting the rim with your fingers.  Gradually work your way around the cover, prying and lifting the rim until it is completely unsnapped from the base assembly.  Lift the protective cover from the gauge. To install the replacement protective cover:  Lay the replacement protective cover on the circular sensor base assembly.  Push down on the outer rim of the protective cover, working your way around the cover until it is completely snapped into place.
