Abstract: Arious researchers tried stabilizing expansive soil with different materials viz. lime, cement, fly ash etc., for the last few decades to improve various properties of soil. Of these, lime stabilization is the best stabilization technique for expansive soil. Lime stabilization of expansive soils involves various physico-chemical reactions which results in reduction of plasticity of the soil. However, the cost of lime stabilizer, in present days, has increased resulting in surge of project cost which led to need for alternative and cost effective waste materials. Quarry dust, one among the alternative materials, is a waste material produced at rock crushing plants. The objective of the study is to investigate the utilization of quarry dust as a suitable proportioning additive to lime stabilized expansive soil for making the resulting mix a cost cutting and effective subbase material. Expansive soil which is procured from the local area, is found to be high plastic in nature. In addition, upon testing, it is found unsuitable for use as subbase material based on CBR value as per MORTH. The soil is then stabilized with lime to make it non-plastic. Then the quarry dust (QD) is proportioned with lime stabilized expansive soil (LS) to obtain optimum mixture that yields a better CBR value. The mix proportions of 60%LS+40%QD, 40%LS+60%QD, and 20%LS+80%QD under study resulted in increase in the CBR value by about 18.3, 21.6, and 24.7 times in comparison with expansive soil. Thus, it is promising to use the quarry dust as suitable additive to lime stabilized expansive soil for using the mix as subbase material in flexible pavements.
