The cover layer of the pavement can be functioned as a structural layer or non-structural layer. Improvement of road surface conditions is done by overlay with additional layers above it or stripping the surface layers of the road. Reclaimed Asphalt Pavement (RAP) or asphalt stripping results into a new problem of aggregate asphalt waste. Utilization of material from the pavement surface layer can reduce environmental pollution and can save maintenance cost. Research has been done by knowing the content of asphalt and gradation of aggregate from stripping asphalt through the extraction process. A few modified asphalts as Asbuton Retona Blend-55 (Asbuton-R) and fresh aggregates have been added to obtain the aggregate bitumen mixture on the specification type of Asphalt Concrete Wearing Coarse (ACWC) mixture. Crumb Rubber (CR) of used tire rubber has been added to the new aggregate and mixed with the old asphalt mixture, and then added asphalt modified Asbuton-R. Crumb rubber (CR) of 0.5%, 1%, 1.5% and 3% were added to each variation of asphalt content ranging from 1.5%; 2%; and 4%. The result of the recycled aggregate asphalt mixture was tested with Marshall Standard and Marshall Immersions on the optimum Asbuton-R content. The deformation resistance of pavement mixture to weather changes has been simulated using Wheel Tracking Machine (WTM) at 26° C, 30° C, 35° C. The results showed that RAP content of more than 80% can still be utilized in the recycling process. The asphalt pavement mixture resistance to rutting deformation due to temperature change, with the addition of 1.5% of optimum Asbuton-R content has shown an increase.
