ARC Laboratory Services offers aggregate testing to Australian Standard AS 1141, ASTM, and Main Roads WA specifications. Our tests assess shape, colour and visual quality, screen for weak and light particles, and check for organic impurities, sugar, clay fines and alkali-silica reactivity, including accelerated and standard mortar bar methods. We also test resistance to stripping. Each test supports confident material selection for road construction, concrete production, and civil engineering projects across Western Australia.
