Insitu stabilisation of pavement materials with cementitious binders is a well-recognised method of rehabilitating pavements for local roads and highways. The expected future development for this technology lies in the methods and protocols for the characterisation of the stabilised materials for pavement design purposes. This paper presents the benefits of in situ stabilisation as well as a brief history of the stabilisation technology and outlines the construction techniques commonly used for insitu stabilisation processes. The various binders available for stabilisation and the characterisation of stabilised pavement materials are also discussed. Finally, the paper presents the expected future developments for the insitu stabilisation industry and recommends that future research focuses on standardising sample preparation and test methods as well as on the development of fatigue-life models applicable to materials stabilised with slow setting cementitious binders.
