PAVEMENTS WITH BITUMEN EMULSION TREATED BASES: PROPOSED MATERIAL SPECIFICATIONS, MIX DESIGN CRITERIA AND STRUCTURAL DESIGN PROCEDURES FOR SOUTHERN AFRICAN CONDITIONS . 5TH CONFERENCE ON ASPHALT PAVEMENTS FOR SOUTHERN AFRICA (CAPSA 89). PROCEEDINGS HELD IN SWAZILAND, 5-9 JUNE, 1989

The concept of treating natural and processed road materials in their virgin state or as recycled materials with bitumen emulsion is not new to road construction technology. The improvements to the engineering properties gained by this method of bituminous treatment are discussed as they are affected by the conditions prevailing in southern Africa. The paper suggests road building material specifications, a mix design method and acceptance criteria and a proposed structural pavement design procedure which takes account of the unique properties of bitumen emulsion treated bases and the environmental conditions of southern Africa. The information given is based on research carried out by authorities in the USA and RSA, in-house research by the authors and results from full-scale road experiments carried out in southern Africa. As this method offers large environmental and economic advantages over other forms of pavement rehabilitation, the results of this paper will hopefully be, a greater understanding and acceptance of this technique of road construction by engineers. In appendix A, a modified marshall test method is described. For the covering abstract of the conference see IRRD 828827.
