RAP asphalt and concrete waste are wastes that are difficult to decompose and can still be reused to reduce the use of new aggregates in the AC- WC asphalt mixture. This study aims to see the effect of adding RAP aggregate and waste concrete aggregate to the marshall volumetric values such as VMA, VIM, VFB, and the Marshall Quotient value of the mixture. The test object is made using the AC-WC specification or wear layer which will then be tested with Marshall Standard and Marshall Immersion tests.

The test begins with testing the characteristics of aggregate, asphalt pen 60/70, and bitumen RAP. To obtain RAP bitumen, extraction was carried out using both methods, namely the Centrifuge method and the Reflux method to determine the asphalt content and aggregate content contained in the RAP. The RAP bitumen that has been obtained will then be added with used oil to restore the asphalt properties to their original properties and then the characteristics will be tested. After that, a test object will be made to be tested by using the Marshall Standard and Marshall Immersion tests to obtain the optimum asphalt content value, and the residual strength index value.

The test results show that the asphalt content in the RAP is 5.6%, the oil content that needs to be added to the RAP is 15% of the total weight of the bitumen contained in the RAP, the KAO value for non-RCA mixtures is 8.5%, and KAO for the RCA mixture by 9%. Based on the results of the Residual Strength Index, it was found that the mixed IKS value using RCA was smaller than those not using RCA."
