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 in this report are from tests conducted at elevated temperatures to evaluate the rutting performance of the two overlay strategies. The tests also investigated the effects of tire type, temperature and thickness of the ARHM-GG overlay. The overlays were placed on existing flexible pavement structures, sections of which were previously tested as part of CAL/APT Goal 1 (5-9). The mix designs and thickness designs for the overlays and their construction are included in References (10, 11).
