Roadbond is a chemical soil stabiliser and a compaction aid. When mixed with soils, it has the effect of reducing shrink/swell activity of expansive clays and enhances compaction of all types of construction materials. The Roadbond molecule contains a hydrophyllic head and a hydrophobic tail. When mixed with soils, the hydrophyllic head attaches to the soil particles and coats the soil particles. The hydrophobic tail repels moisture away from the soil particle surface. This two-fold process is efficiently responsible for reducing shrink/swell activity in expansive clays. Construction materials treated with Roadbond can be re-worked without the need to add more Roadbond. Engineers engaged in road construction and other major earth moving and construction projects such as airstrips, dams and industrial hardstandings, easily understand the cost and other advantages of using Roadbond. Roadbond is only used on site after correct and comprehensive laboratory procedures have been carried out to determine dosage for optimum results in treating the soil being used for the road. Roadbond has been tested on a variety of construction materials and test results have shown that it works effectively on all types of materials ranging from non-plastic to highly plastic materials. Research and development continues with the object of providing users of Roadbond with a product and technical proficiency which is superior in all respects
