Asphalt Pavement Analyzer (APA)

The APA is a three-wheel multi-functional Loaded Wheel Tester (LWT) used for evaluating permanent deformation (rutting), fatigue cracking and moisture susceptibility of both hot mix and cold mix. The APA meets the provisions of the APA Rut Test, AASHTO- 340-10 and Hamburg Test AASHTO 324-

The APA can test mixes at multiple speeds and multiple rates of loading and has a “High Pressure Feature” that allows a user to perform rut testing at high contact pressures for mixes that are used on Federal Aviation Administration (FAA) airport runways/taxiways for P401, Etc. Specifications.

The APA can also be equipped with a Cold Plate that will allow a user to perform Low Temperature Fatigue Testing on Beam Specimens and Low Temperature Studded Wheel Testing on Cylindrical Specimens.

In addition, the APA can be equipped to Perform Micro Surfacing/Slurry Seal Testing (ISSA T147 and T109). Purwheel Testing utilizing solid rubber wheels and pneumatic wheels can also be performed with the APA for Airport and Highway Applications.

The APA can also be used to perform Friction Testing on Asphalt Samples.

The APA is operated utilizing a PLC PC Based Control System. The operating system allows a user to perform all calibrations and functions directly with a Laptop Computer.
