Road as a transport infrastructure is essential to support human activities every day, the road can improve people's lives by enabling people to access the surrounding environment both for the economic aspects and social aspects. Using the technology development to make a human being willing to innovate - innovation to create technology that is becoming increasingly efficient one is with recycling technology. Recycling technology is also applied to the RAP (Reclaimed Asphalt Pavement), which is a waste material pavement, scraping pavement material is later testing and repairs to improve the quality of the waste so that it can be used again properly.The purpose of this investigation is to determine how much the value of density and carrying capacity by gradation EME RAP material, is then compared with the density value and the carrying capacity of fresh aggregate by the same gradations. In this study, the test was conducted on the test density, abrasion, inspection aggregate gradation, density and CBR (California Bearing Ratio). In this study, samples with a total of 18 specimens. This research was conducted at the Laboratory of Civil Engineering pavement materials Muhammadiyah University of Surakarta.Research results show that the new aggregate value higher density than the material well in testing strandart RAP or modified proctor proctor, new aggregate optimum moisture content is also higher than the RAP material. The new aggregate maximum density at standard proctor reached 1.820 gr / cm3 with optimum moisture content of 9.8%, and the RAP material reached 1.495 gr / cm3 with a water content of 9.6%, while the modified proctor reached 1.960 gr / cm3 with optimum moisture content 9 , 25% and RAP material reached 1.590 gr / cm3 with optimum moisture content of 8.3%. Results of testing the carrying capacity of the CBR tool to use your new aggregate material is higher than the RAP is to aggregate only reached 86.67 and reaches 33.33 RAP materials. From the results of this study concluded that the density value and the carrying capacity of RAP material is still lower than the new aggregate.
