Volumetric of Eco-Friendly Asphalt Mixture Containing Local Limestone, Sea Sand, Portland Composite Cement and Buton Modified Asphalt

Abstract

This study used local limestone, sea sand, Portland Composite cement (PCC), and modified Buton asphalt (MBA) to create asphalt mixtures for asphalt concrete wearing course (AC-WC) layers. The combined aggregate was successfully designed within the required standard specification range (General Road Works Specifications by DGH in 2010). At an MBA content of 5.7 and 6.1%, the PCC and MBA showed a positive contribution to the binding of aggregates so that the mixture meet the satisfactory performance of asphalt mixtures in terms of volumetric properties, which include VIM, Voids in Mineral Aggregate (VMA) and VFB.
