Troxler continues to set new product standards of quality and precision in the construction industry. For a complete list of Troxler equipment, please review this Products section.

The PaveTrackerTM Model 2701-B Plus is an electromagnetic density indication device for asphalt quality control measurements. This gauge contains no radioactive material, so no licensing or special training is required to own or operate this equipment. Your entire asphalt paving team could be ready to perform asphalt quality control measurements at a moment’s notice.

The PaveTrackerTM Model 2701-B Plus weighs only 11 lbs (5 kg), and it displays measurement results in only two seconds. This allows the user to measure larger areas in a shorter amount of time. If problem areas are found, further compaction effort can quickly be made to increase the density of the asphalt.

The PaveTrackerTM Model 2701-B Plus complies with ASTM standard D7113 and AASHTO T 343.
