ABSTRACT

This paper aims to determine the Marshall properties of Asphalt Concrete-Wearing Course (AC-WC) and Hot Rolled Sheet-Wearing Course (HRS-WC) with the utilization of concrete waste and also to determine the percentage of concrete waste added into AC-WC and HRS-WC as the substitute for coarse aggregates. During the manufacture of asphalt mixtures, coarse aggregates, and fine aggregates are required in large quantities. To reduce fresh aggregates in the manufacture of asphalt mixtures for road pavement, concrete waste has become an alternative. This study used 60/70 penetration asphalt, coarse aggregate, fine aggregate and concrete waste of 0%, 20%, and 40%. The test was conducted using Marshall test tool, which consisted of two stages of testing. The first stage, Marshall test, was performed to determine the optimum bitumen content of asphalt mixture with a concrete waste variation of 0%, 20%, and 40%. The second stage of Marshall test was conducted to determine the Marshall properties (stability, flow, Marshall Quotient, VMA, VFWA, and VIM) by performing in the asphalt mixture with concrete waste variations of 0%, 20%, and 40%. The results showed that as a performance indicator of asphalt mixtures that acted as the variation addition in concrete waste in AC-WC and HRS-WC asphalt mixtures, Marshall properties decreased in Stability values, Marshall Quotient and VFWA, whereas the values of Flow, VIM, and VMA experienced an increase. The utilization of concrete waste up to 20% as the substitute for coarse aggregate was acceptable for respective AC-WC and HRS-WC asphalt mixture. The maximum acceptable variation of concrete waste was 35% for AC-WC asphalt mixture and 29% for HRS-WC asphalt mixture.
