Chemical stabilization has been extensively used for the improvement of weak soil, in improving the shear strength as well as limiting the deformation behaviour of the ground. Plenty of researches regarding the effectiveness of using industrial waste as a chemical stabilizer are also increased rapidly. The aim of this research is to evaluate the engineering properties of Nilai weak soil mixed with fly ash which is an industrial waste. This research present the stabilization weak soil using Class C fly ash at varying stabilizer contents (5%, 10%, 15%, 20% and 25%). Classification of soil such as Liquid Limit test, Plastic Limit test, Sieve Analysis and Standard Proctor test were carried out to determine the properties, optimum moisture content and maximum dry density of the untreated soil. The basic properties of soil such as Unconfined Compression test (UC) and California Bearing Ratio test (CBR) were used to gauge the behaviour and the performance of the stabilized soil. From the analysis of the results, the addition of fly ash increase the shear strength of the soil. The carried out tests gave some indication that the unconfined compressive strength (UCS) and the California Bearing Ratio (CBR) increase with the increase of percentage of stabilizer and curing period of 3 and 7 days. As a conclusion, the results show that the stabilized soil sample achieved its optimum strength at 20% of fly ash content with 7 days of curing period. At 25% of fly ash content the strength begin to drop as fly ash not a very strong stabilizing agent.
