Abstract
This study examines the use of brick powder (BP) reclaimed from construction and demolition waste as a filler in a hot-mix asphalt (HMA) in hot and desertic areas. For this research, two HMA mixtures were designed using different fillers: one using BP and the control using limestone powder (LSP). Readily available natural desert sand was also used in the mix. The samples were subjected to rutting, creep compliance, indirect tensile strength modulus (ITSM), and moisture susceptibility tests. The results were that the mixtures using BP had superior mechanical characteristics to mixtures using LSP. BP showed a marked improvement on asphalt pavement performance, and it resulted in a flexible road pavement with a long expected lifespan.
