| Abstract | The purpose of this study is to determine the appropriated mixed proportion of asphalt concrete using Polymer Reclaimed Asphalt Pavement, new aggregate and Advera (PRAP- Warm Mixed) that were mixed at warm temperature. Then the Mechanical Properties of new mixed asphalt concrete samples were tested following the standards of the Department of Highway, Thailand. In experimental design, the range of mixing temperature varied as 140บC, 145บC, 150บC, 155บC, and percentage of Advera added varied at 0.20, 0.25, 0.30 and 0.35 percent by weight of aggregate. The engineering properties of PRAP samples obtained from this study showed that the optimum mixing ratio was 0.20 percent at 140บC has a Stability value of 2530 lbs, a flow of 12 in a particle size of VMA 16.2, a strength index, 85 percent of the test results are in line with the requirements of the Department of Highways. Then using 70 percent of PRAP-warm mix with 30 percent of new material at 140 ?C and add 0.20 percent of Advera that is the best-mixed proportion. The normal temperature of PMA mixing is higher than 170บC, in this case using PRAP-Warm mix can reduce temperature lesser than 150บC then this mixing process can save fuel consumption. Thus this study is useful for environmental perspectives. |
