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

The Model 2701-B is a lightweight device, weighing only 11 lbs. (5 kg) and displays measurement results in only two seconds! These features allow the technician 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.
