Study on cement-treated soil with roadcem additive in construction of rural roads: A case study in Viet Nam

Abstract

The use of soil in place for road construction could reduce construction cost and environmental impact because this method can replace the traditional materials that are depletion such as sand, gravel. This paper presents the laboratory results for selecting proportion and inspection testing results of experimental road construction using cement-treated soils with RoadCem additives. RoadCem additive improved the hydration of cement when cement reacts with soil particles, thus increasing the strength of reinforced soils, especially tensile strength. The results of inspection tests showed that the average of compressive strength, tensile strength, and modulus elastic in the saturated condition of reinforced soil satisfied the design and standard requirements in Vietnamese standard.
