An Evaluation of the Tropical Soils Subjected Physicochemical Stabilization for Remote Rural Roads

The rural, forest roads are basic and important elements in the economic progress and social promote procedures for health, income, Facilitate Future Development, Technology Transfer and education potential of the communities of remote areas in Malaysia. Using chemical material additives such as waste polymer, cement, lime and sulphuric acid treated mineral oil as the soil stabilizers used to improve these roads was the main aims of this study. We studied an evaluation to develop the durability and geotechnical strength properties of tropical laterite soils. Their behaviour was tested to determine their influence into the surface of tropical remote access roads. It was found that the increase in strength of cushioned laterite soil reaches to maximum after 14 days for both soaked and unsoaked conditions in unconfined compressive strength test (UCS), the considered chemical stabilizers are recommended for using on low cost unpaved roads to reduce construction and maintenance charges as well as assurance the unpaved roads strength in rainy weather and dust-free in dry conditions.
