“…These natural materials generally contain a greater amount of fi nes, and the fi nes have higher plasticity, than is accepted by many existing specifi cations for construction materials. Details of materials which have been successfully used as road base construction materials in the tropics are given by Lionjanga et al (1987), Grace and Toll (1989), Gidigasu (1991), Metcalf (1991), Netterberg (1994) and Gourley and Greening (1997).…”

The results of shear box and consolidation tests on electrokinetically-treated tropical residual soil are presented. Injections of selected chemicals (calcium chloride, aluminium chloride and phosphoric acid) into the soil samples at the anodes or cathodes were carried out in cylindrical electrokinetic cells via applications of 30 V DC electrical potential for 168 h. Four different open-anode and open-cathode electrokinetic systems utilising different anolytes and catholytes were employed to treat the soil samples. The shear resistances of the treated soil utilising distilled water as the anolyte and 1·0 mol/l phosphoric acid as the catholyte was enhanced, whereas the treated soil near the cathode showed significant reduction in compressibility. Soil treated utilising the other chemicals showed no significant changes.

“…Trial constructions in Kenya of low-volume roads surfaced with a sprayed bituminous seal coat compared lateritic gravel with conventional crushed stone for the road base (Grace and Toll, 1989). It was found that the lateritic gravel sections showed better performance.…”
