Abstract: This report presents results from accelerated pavement tests using the Caltrans Heavy Vehicle Simulator (HVS) of DGAC and ARHM-GG overlays placed at the University of California Berkeley Pavement Research Center. The results presented in this report are from four tests conducted at 20 degrees C to evaluate the performance of the two overlay strategies with respect to cracking (fatigue or reflection), and rutting of the unbound pavement layers. Both overlay strategies were evaluated on previously tested drained and undrained flexible pavement structures. The overlays were placed on existing flexible pavement structures, sections of which were previously tested as part of CAL/APT Goal 1. The mix designs and thickness designs for the overlays and their construction are included in References (10, 11).
