  • Page 16: Features

    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 two seconds, saving time and money.
  • Page 17 The PaveTracker allows the operator to specify the layer thickness; the value entered is stored with other measurement data. Measurements can be adjusted using a density offset or mix calibration (which includes slope and intercept values) 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.

    Status The gauge Status display enables the operator to view gauge status information, including the battery voltage, internal temperature, selected measurement units (see page 2–8), the time and date of the last reference reading (see page4–2), and GPS satellite and fix status. To access this information, press the 〈STATUS〉...

  • Page 27: Setup Menu

    Setup Menu After turning the gauge on for the first time, set up the software. The gauge stores the software setup, so the operator does not need to enter a new setup each time the gauge is turned on. The gauge setup includes the measurement units (Metric or English), date and time, temperature, customer name, external beeper setup, GPS, user ID, mix calibration, and the layer thickness function.
  • Page 28 Set Units The gauge can display measurement results in either metric (SI) or English units. To set the units, press 〈1〉 at the Setup menu shown on page 2–7. The gauge displays: - Uni t s- 1. Engl i sh 2.

  • Page 35: Target

    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.

  • Page 40: Introduction

    Introduction Troxler recommends referencing the gauge each day that the gauge is in use 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.

  • Page 41: Offset

    Offset To improve the accuracy of the PaveTracker Plus for a specific material of known density, the unit can be calibrated using a density offset. A density offset is determined by taking in- place measurements using the PaveTracker Plus, then comparing the measured density to an alternative density, as determined using a nuclear gauge reading or road core extraction and analysis.
  • Page 42 3. Determine the alternative density of the material using a nuclear gauge reading or road core extraction and analysis. Be sure to conduct the gauge measurements or core extraction in the same location as the PaveTracker Plus reading. 4. Subtract the measured density from the alternative density to determine the density offset to be entered into the PaveTracker Plus software.
  • Page 43 To enter a new density offset, press 〈3〉. The gauge prompts for the density offset as shown below: Dens i t y Of f set #. ## pcf Sel ect ( +/ - ) To change the offset, use the arrow keys to select the offset sign (positive or negative).

  • Page 44: Mix Calibration

    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.

  • Page 51  Repeat the referencing process. If the reference result still does not pass, contact Troxler technical support (see the front of this manual for a list of service centers and their contact information).

  • Page 52: Preparing A Test Site

    Preparing a Test Site To ensure measurement accuracy, properly prepare the test site before taking gauge measurements. 1. Locate a smooth site on the asphalt. 2. 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.
  • Page 53 CAUTION High internal temperatures may damage the gauge’s electronic components. To reduce the risk of damage, DO NOT allow the gauge to sit on hot asphalt for extended periods. If the internal temperature of the gauge reaches a level that is considered excessive, the beeper will sound and the warning message Internal temp.
  • Page 54 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. 1.
  • Page 55 NOTE The latitude and longitude display, showing the location of the measurement, is available only on the PaveTracker Plus gauges equipped with the GPS option and is shown only when this option is enabled. The latitude and longitude value denote the quality of the location fix.
  • Page 56 Averaging Mode In averaging mode, you can take up to 30 measurements at selected locations. The gauge will calculate the average of these measurements, allowing you to determine the average density over a larger area. 1. Extend the telescoping handle (see Figure 1–1) to reduce the bending required while taking measurements.
  • Page 57 5. 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 Meas ur ement Do You Want To St or e ?

  • Page 62: Handling Project Data

    Handling Project Data The Model 2701-B can store approximately 1000 readings. The Project and Store functions allow handling of measurement data. Measurement results are stored in files (memory locations) called projects, which are named by the operator. The Project function allows the operator to create a new project, view project data, select a project (make an existing project active so that additional data may be added to it), output the data stored in the project, or erase projects.

    COMPUTER 1. Inspect the contents of the shipping case. If the shipping case or any other part or accessory appears damaged, notify the carrier and your Troxler representative immediately. 2. Check that the correct cable is being used. 3. Ensure that the printer/computer baud rate is 9,600 bps.
  • Page 77 SHORT BATTERY LIFE AFTER RECHARGING 1. 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. 2.

  • Page 78: Internal Gauge Temperature

    Internal Gauge Temperature High internal temperatures may damage the gauge’s electronic components. To reduce the risk of damage, DO NOT allow the gauge to sit on hot asphalt for extended periods. If the internal temperature of the gauge reaches a level that is considered excessive, the beeper will sound and the following warning message is displayed: I nt er nal t emp.

  • Page 79: Batteries

    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.
  • Page 80 Replacing the Batteries To replace the NiMH battery pack (PN 110374): 1. Turn the gauge off. 2. Using a 1/8-inch Allen wrench, remove the two screws that secure the battery cover to the base of the unit. 3. Clean the screws and set them aside. 4.

  • Page 81: Cleaning The Base And Top Shell

    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. CAUTION Be careful not to scrape or scratch the round sensor, as damage to the sensor may cause erroneous readings. Also be careful not to damage the gauge base.

  • Page 82: Replacing The Protective Cover

    NOTE Additional bottom cover discs can be purchased from Troxler by ordering PN 113103, Cover Replacement Kit, which includes three discs. To remove the old protective cover disc: 1. Turn the gauge over so that its bottom surface is exposed.
  • Page 83 3. Align the replacement cover disc with the sensor and press it into place. Smooth out the disc to eliminate air bubbles. NOTE Do not remove and re-install the same cover disc, as the adhesive will be weakened. Model 2701-B Appendix A–9...
