| Abstract | The article presents the study of physical characteristics of warm mix asphalt cementconcrete (WMA), components designed by the Marshall Method. Stability, flow rate,strength index, air void, and percent voids in mineral aggregate (VMA) of a total of 77specimens were examined as a general standard specification test of the Department ofHighways, Thailand. Limestone was used as aggregate. Adhesive mixtures of asphaltgrade 60/70 were mixed with admixture ?ADVERA? to the ratios of 0.20%, 0.25%,and 0.30% by weight of aggregate. WMA-mixing and compaction temperatures werecontrolled at 115?C, 120?C, and 125?C. The results were that the asphalt cementmixed with 0.25% of ADVERA (by total mixed) at 125?C shows the best mechanicalproperties standard, with higher value of stability (2,200lbs, i.e., more than the standard1,800lbs), flow rate, air void, VMA and hardness index. Finally, this study indicatesthat asphalt concrete added with admixture ADVERA (WMA) could reduce the mixingand compaction temperature during production processes from >160?C to ? 125?C. |
