ABSTRACT

Solid waste is increasing throughout the world due to rapid population growth and the need for infrastructures. Reports have shown that Indonesia contributes 3% to this solid waste due to the demolition of highways constructed using concrete pavement and others. However, the waste can be processed into recycled concrete aggregate (RCA) which has the potential to be reused as an alternative for new pavement materials to reduce the use of natural aggregate (NA) and achieve environmental sustainability. Therefore, this study aimed to discuss the application of RCA with concrete grade Fs 4.5 on Asphalt Concrete Binder Course (AC-BC) mixture. RCA with 12.5 mm and 9.5 mm thickness was applied as a 45%, 50%, and 55% substitute for NA in AC-BC mixture. Marshall Immersion and Cantabro Loss tests were later conducted to analyze the residual strength and grain release resistance. The results showed that the application of RCA had a positive effect on AC-BC mixture with the sample containing 55% observed to have a stability of 1909.79 kg. The Marshall Immersion test also showed that the sample with 50% RCA had the largest residual strength of 94.41%. Furthermore, the use of RCA as a substitute for NA in AC-BC mixture led to an increase in Marshall stability in the range of 0.41% to 29.24% compared to the application of 100% NA. Cantabro Loss test results for mixture with RCA replacement were observed to have increased by 6.46% to 7.26% when compared to a mixture with 100% NA. The highest Cantabro Loss value was recorded for 45% RCA at 7.26% while the lowest was for 55% RCA at 6.46%. However, the required Cantabro Loss value was less than or equal to 20% which pointed the ability of the proposed asphalt mixture to resist degradation against wear usually caused by vehicle tire friction. In conclusion, Marshall and Cantabro Loss test results showed that the proposed mix was resistant to wear and could withstand traffic loads effectively by distributing the loads to the underlying layers to support the pavement as a whole.
