Properties of WFS Incorporated Cement Stabilized Lateritic Soil Subgrades for Rural Pavement Applications

This paper presents extensive experimental investigations carried out on stabilizing lateritic soil subgrades using Waste Foundry Sand (WFS) and Ordinary Portland Cement (OPC) stabilizer. From the preliminary geotechnical investigations (gradation and proctor density), the content of WFS and OPC were fixed to be 30% and 8%, respectively. The stabilization is attributed to the combination of mechanical stabilization through the improvements in the gradation (through WFS) and the chemical stabilization (through OPC) of the soil grains. Unconfined Compressive Strength (UCS) and California Bearing Ratio (CBR) tests were carried out for the selected mixes at regular intervals. The flexible pavement composition design (as per Indian standards) and the results of the analysis of pavement structure using KENPAVE software have also been presented in this paper. The durability studies in terms of wetting–drying cycles and freezing–thawing cycles were carried out. Microstructure studies (using FE-SEM) and chemical profiling (using EDX, XRD, and TGA) were also carried out to understand the binding mechanisms and the mineralogical changes upon the WFS-OPC stabilization in lateritic soil. Results reveal a considerable improvement in the engineering properties of the lateritic soil through the WFS-OPC modifiers through which economical design of pavements can be achieved for Indian local-rural road applications.
