Abstract

In several regions of Indonesia, flexible pavement layers are extensively utilized. On the other hand, large loads on restricted pavement necessitate pavement repair. An overlay is frequently applied to hide the damage. In order to prevent overlays, road deterioration can be handled by removing the old road surface with a cold milling machine. However, used asphalt that has been disassembled using a cold milling machine is frequently discarded. Dismantling damaged or outdated pavement that has reached the end of its design life yields reclaimed asphalt pavement (RAP), which can be used as a replacement for asphalt and aggregate in road pavement and road shoulders to create new pavement with the goal of minimizing material waste. The purpose of this study was to evaluate the impact of reclaimed asphalt pavement on newly constructed AC-BC mixed pavement. The RAP material for this study came from the Bangkinang-Petapahan road in Kampar Regency, while the fresh aggregate came from Pangkalan. After being chosen, each material undergoes sieve analysis, specific gravity testing, and extraction testing for RAP materials. The material test results are then combined using the percentage of the gradation combination for a test sample. In order to get the desired RAP levels of 25%, 50%, 75%, and 100%, four (four) test sample pieces were made. Each sample must pass the Marshall test in order to determine the characteristic values of the AC-BC mixture. The 2010 and 2018 Bina Marga requirements shall be followed while modifying each material test. The investigation of the AC-BC mixture's RAP composition using new aggregate reveals that RAP has an impact on the Marshall characteristic value. The combined aggregate's effective specific gravity decreases with increasing RAP concentration. This impacts the Marshall Quotient (MQ), stability, melting, and the proportion of void in mix (VIM), void in minerale aggregate (VMA), void filled asphlate (VFA), and void in mix (VIM). A Marshall Quotient (MQ) value of 1,591.60 kg/mm was the highest value recorded in the 100% RAP sample. This indicates that the mixture with a 100% RAP concentration is more rigid. More rigidity will help prevent deformation.
