Literature review: stabilised sub-bases for heavily trafficked roads.

Abstract

Stabilization is the process of mixing a stabiliser, for example cement, with a soil or imported aggregate to produce a material whose strength is greater than that of the original unbound material. The use of stabilization to improve the properties of a material is becoming more widespread due to the increased strength and load spreading ability that these materials can offer.

Stabilization technology is extremely relevant for heavily trafficked pavements where its benefits are beginning to be appreciated.

This report describes the basic types of stabilization, indicates when it should be used, and discusses the main advantages and disadvantages of its use. The role of the subbase and other pavement layers are also discussed for both flexible and rigid pavements.

An extensive literature review of international publications was carried out and this report describes some of the latest research and design methodology associated with stabilized materials used for sub-bases on heavily trafficked roads. As well as references to the literature it also contains an extensive bibliography of work on this subject.
