CHEMICAL STABILISATION FOR LOW COST ROADS IN BOTSWANA

During road construction, especially on unsurfaced earth and gravel roads, many problems can arise including deterioration of the surface and dust on the road. Because road maintenance is costly and disruptive to traffic flow, stabilization of some local road materials during construction is necessary. This paper discusses experimental research conducted on the use of the chemical soil stabilizer Con-Aid for stabilization of low cost roads and rehabilitation of existing roads. Con-Aid is a water-soluble, anionic compound with surface-active properties, and is non-toxic and environmentally friendly. Two types of soils in Botswana were used in the research, and lab tests on treated and untreated soil samples were carried out to establish the engineering properties of the soil. It is recommended that Con-Aid be used as a stabilizer on low cost roads, as it will reduce construction and maintenance costs, ensure that the roads remain passable in rainy season, and dust-free in dry season.
