This paper presents the influence of fly ash on the mechanical properties and drying shrinkage of cement treated aggregate crushed stone (CTACS) mixture. The fly ash can replace 20-40% the weight of cement for the mixture of 4% CTACS, while it can supplement 3-9% the weight of aggregate crushed stone for both mixtures of 3% and 4% CTACS. Furthermore, the experimental findings indicated that the reduction in the compressive strength and the splitting tensile strength of CTACS was inversely proportional to the fly ash content replaced partially by the cement. However, the increase in the compressive strength and the splitting tensile strength of CTACS was directly proportional to the fly ash content. It was observed from the test results that the drying shrinkage of all mixtures was smaller than the control mixture without fly ash. The drying shrinkage of mixtures reduced inversely to the proportion of the fly ash content when 20-40% cement was replaced by the fly ash. When adding 3-9% fly ash, the 6% fly ash gave the smallest drying shrinkage.
