Development of hot mixes of asphaltic concrete with rubber scrap natural

Abstract

This research presents the engineering properties of asphalt (AC 60/70) modified with different ratios of scrap natural rubber. Then select the best properties of the binder to mix asphaltic concrete. From laboratory testing results, with adding 7% scrap natural rubber into mixtures for the best results. The properties of asphaltic concrete can be improved by adding 7% scrap natural rubber. For asphaltic concrete, Marshall Stability increased with adding scrap natural rubber into asphalt. Moreover, the stiffness modulus of asphaltic concrete can be improved 13.53 compared to AC 60/70.
