This study is to assess the suitability of Reclaimed Asphalt Pavement (RAP) as a coarse aggregate substitution for flexible pavement mixture. The RAP in this investigation was taken from roads in Padang, Indonesia. There were three types of flexible pavement chosen to be tested for RAP substitution, i.e. Asphalt Concrete-Wearing Course (AC-WC), Asphalt Concrete-Binder Course (AC-BC), and Hot Rolled Sheet-Wearing Course (HRS-WC). Laboratory studies have been carried out on flexible pavement mixes with RAP material and their performance has been compared with flexible pavement without RAP substitution. Marshall tests were carried out in laboratory as per 2010 specification 6th division from Indonesia Public Work Department standard. The effects of RAP on physical and rheological properties of the final bituminous blend were investigated. The research aims to find out the effect of RAP as coarse aggregate substitution to the flexible pavement characteristics, i.e. Stability, Flow, Marshall Quotient (MQ), Void in Mix (VIM) and Void in Mineral Aggregate (VMA). The percentage of RAP substitution is 35%, 55%, and 60%. From the results of the tests in the laboratory, it was concluded that the AC-WC pavement was more appropriate due to, it has achieved the highest Marshall stability, with VIM, VMA, and VFB were in the standard.
