ABSTRACT

The recycling technique using materials produced by Cold Milling Machine is a potential alternative to be applied to road maintenance in Indonesia. This study aims to investigate the properties of Reclaimed Asphalt Pavement (RAP) used as Asphalt Concrete Wearing Course (AC-WC) so that the proportion of additional fresh aggregate can be determined. This laboratory-scale study uses the material of RAP from Semarang Section A toll road sections and penetrated asphalt of 60/70. The extraction analysis obtained asphalt content is between 3.50% - 4.36%, with abrasion of 29.04%. RAP cannot be used directly but there is a need to add fresh aggregate so that the mixture meets the specifications. The proportion of the mixture is 30% of RAP, 18% of the fresh aggregate, 50% of rock ash, and 2% of Cement. The analysis shows that the mixture with optimum asphalt content (5.7%) obtained 1188 kg of stability, 4.02% of VIM, 15.81% of VMA, 74.54% of VFWA, and 3.57 mm of flow. These values indicate that the mixture meets the revised version of the Technical Specifications of Bina Marga 2010. Therefore, it can be said that this mixture has high durability, good density, and is resistant to the possibility of bleeding.
