| Summary: | Soil stabilisation is the alteration of one or more soil properties, by mechanical or chemical means, to create an improved soil material possessing the desired engineering properties. In pavement engineering, soils as a main pavement construction material may be stabilised or/and modified to increase strength and durability or to prevent erosion and dust generation. This paper will report the relevant design and the practical viewpoints of soil stabilisation in Western Australia pavements. The Hydrated Cement Treated Crush Rock Base (HCTCRB) material and the foamed bitumen stabilised material will be demonstrated through their mix design philosophy, laboratory and field investigation, and performance.
