Asphalt Pavement Analyzer (APA)

The HM-459 Asphalt Pavement Analyzer (APA) by Pavement Technology is a three-wheel, multi-function Asphalt Wheel Tracker for the accurate evaluation of rutting, fatigue cracking and moisture susceptibility of hot and cold asphalt mixes. This versatile model complies with AASHTO methods T 234 Hamburg Test (with solid wheels) and AASHTO T 340 APA Rut Test (with concave wheels). The environmentally controlled chamber can test samples in dry or submerged conditions and the exclusive high-pressure feature generates 250psi or more for advanced testing of mix designs for airport runways and taxiways.

The unique drive system allows simultaneous testing of multiple samples at different speeds and load rates. Three rectangular slab or beam specimens or six cylindrical specimens can be tested at the same time using Gyratory, Marshall, or vibratory beam samples molded in the laboratory or field cores cut from the existing pavement. In a single pass, five or more measurements can be collected on a beam specimen and three or more on a cylindrical specimen. This extremely accurate system calculates the data to 0.00001mm.
