Paper presented at the 25th Annual Southern African Transport Conference 10 - 13 July 2006 "2010: Will transport infrastructure and systems be ready?", CSIR International Convention Centre, Pretoria, South Africa. ABSTRACT: The use of SAWDIA (Soluble Adsorbed Water Displacing Ionic Additives) has not been as extensive in South Africa as the products really merit. These liquid stabilizers have been on the market in South Africa for over 30 years but even today many road engineers are not in favour of their use. This paper is an attempt to clarify some of the misunderstandings regarding the use of these products and to note where they do or do not give acceptable results.
