Abstract

The use of alternative materials as fillers in asphalt mixtures is an innovative solution to improve road quality while utilizing construction waste materials. This study examines the effect of using crushed lightweight bricks as aggregate fillers in Asphalt Concrete Wearing Course (AC-WC) mixtures. The research was conducted through experimental methods in the civil engineering laboratory of Universitas Muhammadiyah Surakarta. The experiment utilized crushed lightweight bricks ground into fine particles with mixture variations of 6, 7%, 8%, 9%, and 10%. The objectives of this research were to utilize lightweight brick waste, evaluate the mechanical performance of asphalt mixtures with lightweight brick fillers through Marshall tests—including Density, Flow, Voids in Mineral Aggregate (VMA), Voids in Mix (VIM), and Voids Filled with Bitumen (VFB)—and determine the optimal content of lightweight brick filler for AC-WC asphalt mixtures. The results indicate that using 10% lightweight brick waste as aggregate filler with an optimal asphalt content of 6% improves the Marshall characteristic values. The use of mixed materials as aggregate fillers can involve waste products or binding materials. Crushed lightweight concrete waste has been shown to improve the performance of the mixture when used in optimal proportions. The optimal filler content varies depending on the type and quality of the materials used.
