Asphalt Pavement Analyzer - APA
A multifunctional loaded wheel tester used for valuating permanent deformation (rutting), fatigue cracking, and moisture susceptibility of both hot and cold asphalt mixes.
The APA can test gyratory, vibratory, marshall specimens, field cores & roadway
slabs in a temperature controlled chamber. A repeated load is applied to the test
specimens in a dry or wet condition. A typical test runs 8000 cycles and takes 2
hours & 15 minutes to finish. In this period of time the APA can predict how
an asphalt mix will perform during it’s life span. Users are able to avoid
failures and maximize profits by having reliable and accurate performance data about
the aggregates, asphalt’s, polymers, and related materials.
The APA features an Automated Data Acquisition System that obtains all rutting measurements and plots them in a graphical and numeric format.
