Abstract

Aggregate quality is critical to long-term pavement performance and increased maintenance costs. Choosing the right aggregates is essential to sustainable roads. For areas like Sarawak, Malaysia, knowledge of the characteristics of the locally available aggregate is an essential for optimizing their use in construction projects. The aim of this paper is to conduct a thorough investigation into physical and mechanical properties of rock aggregates from various localities in Sarawak, Malaysia, where the location information can give some inference on its suitability for pavement construction use. The research assesses key aggregate characteristics that are measured through a series of laboratory testing which typically includes Flakiness Index, Aggregate Crushing Value, Water Absorption Test, and Los Angeles Abrasion Value. The results are presented in a descriptive way, providing the characteristics of aggregates sourced from various quarries at different locations throughout Sarawak. The results are compared and evaluated against Jabatan Kerja Raya (JKR) Malaysia standards, thereby providing information on the suitability of aggregate properties for pavement construction. This study therefore increases the knowledge of regional aggregate sources in Sarawak.
