Abstract
Indonesia is one of the world’s largest latex producers. Latex can be used as an asphalt modifier on road pavements. The level of road damage in Indonesia is high. The purpose of this research was to describe the effect of using DRC-30 latex on Asphalt Concrete in terms of Marshall parameters. The test specimens are made using two kinds of asphalt concrete (AC) gradations, namely the Asphalt Concrete Wearing Course (ACWC) gradation, and the AC-Base gradation. Test data were analyzed using Marshall parameters, namely stability, flow, void in mix (VIM), and void filled with asphalt (VFA). The test results showed that latex increased the stability value in all types of gradations. Latex increased the value of Flow AC-Base, but decreased the value of flow at ACWC. The addition of latex to AC decreased the VIM value of AC-Base and ACWC. Meanwhile, the addition of latex to AC-Base and ACWC increased the value of VFA, the highest increase was for AC-Base. Based on Marshall parameters, the best performance of AC due to the addition of latex is in the AC-Base gradation.
