This document summarizes a study on soil stabilization using cement and marble dust for highways. The study involved testing various mixtures of soil, cement, and marble dust to determine their engineering properties. The key findings from the experiments were:
1) The maximum dry density and optimum water content varied with the addition of cement and marble dust. The highest dry density of 2.4 g/cc was achieved with 24% cement addition.
2) CBR values increased with the addition of cement and marble dust. The highest CBR values of 21.23% unsoaked and 23.45% soaked were achieved with 24% cement addition.
3) Cement was found to be a better stabilizer than marble
