Compressive strength of asphalt concrete binder course (AC-BC) mixture using buton granular asphalt (BGA)

Abstract

This study aims to evaluate the compressive stress-strain relationship of asphalt concrete mixtures using Buton granular asphalt (BGA) as partial replacement for petroleum asphalt in asphalt concrete bearing course (AC-BC) mixture production. The experimental tests show that the stress-vertical strains curve and stress-horizontal strains curve pattern were similar for all mixtures. The application of BGA as partially replaced petroleum asphalt in the AC-BC mixture improved the compressive strength and elastic modulus in comparison to AC-BC mixture without BGA. No significant difference in the Poisson ratio for all mixtures was observed.
