Abstract: Stone Matrix Asphalt (SMA) is hot mixture asphalt consisting of a coarse aggregate skeleton and a higher binder content mortar. To minimize the pollution from waste tires and to improve the properties of SMA, Recycled Crumb Rubber (CR) plus Low Density Polyethylene (LDPE) flakes were used as additive using dry process as a research study. This research investigated the feasibility of using 15% and 30% CR+LDPE by weight of bitumen with 60/70 penetration grade bitumen for SMA. SMA mixture meeting the desired volumetric properties could be produced using the combination of 30% (Combined Combination with 30% CR and 70 % LDPE) by weight of the bitumen). No fiber was needed to prevent drain down when this rubber blend was used. Based on results of indirect tensile tests, unconfined compression test and variance analysis, it was observed that the addition of recycled CR+ LDPE using dry process could improve engineering properties of SMA mixtures, and the rubber content has a significant effect on long term performance.
