Determination of Suitable Proportions of Stabilizing Materials based on Soaking and Infiltration Rate Parameters

Abstract

Material stabilization and the rate of moisture absorption are critical factors in enhancing road infrastructure performance. To evaluate these aspects, laboratory tests were conducted to determine the engineering characteristics of materials prepared with specific ratios of blended gravel and sand. Stabilization, in this context, involves blending aggregates or soil with additives such as bitumen, ground granulated blast furnace slag (GGBS), Portland cement, lime, or sludges to improve mechanical strength.

This research particularly emphasizes the optimization of mix proportions using GGBS and Ordinary Portland Cement (OPC) as stabilizers, with a focus on the partial substitution of cement with GGBS. Laboratory test results demonstrate the potential of these blends to enhance the resistance of road materials to water infiltration and traffic-induced loading. The study ultimately identifies best strategies for improving the quality of fill material and its application in embankment construction, especially in waterlogged areas.
