Massive quantities of industrial wastes such as stone industry waste are obtained yearly. The generated limestone waste that deposits into landfills may be decreased via using in building materials preparation. In this study, crushed limestone (CLS) was used to enhance the geotechnical properties of CL soil of Sulaimani governorate, northern Iraq. Consistency, compression, and compressibility characteristics were examined and evaluated. CLS was added by 0%, 5%, 10%, 15%, and 20% as a replacement from the dry mass of the natural soil. Experimental results by using CLS yielded a notable level of improvement of the expansive soils geotechnical properties. Essential modification in the geotechnical properties was achieved due to the addition of 20% of CLS. Good correlations among some of the geotechnical parameters of the stabilized soils by CLS were obtained.
