Experimental and Modeling Studies of Resilient Modulus and Permanent Strain of Stabilized Fly Ash
In the present investigation, geotechnical properties of fly ash lime (FAL) mixes and fly ash cement (FAC) mixes were studied for their use as a subbase material for flexible road pavements. The effects of lime content, cement content and curing age on unconfined compressive strength (UCS), resilient modulus, and permanent strain of these mixes were studied. Fly ash with minimum 6% lime content and fly ash with minimum 6% cement content satisfy the minimum strength criteria recommended by the Indian Road Congress (IRC) for their use as subbase materials. These mixes exhibited higher resilient modulus than the conventional granular subbase (GSB). The influence of wetting-drying (W-D) cycles on resilient modulus was also reported in this study. The fitting of different existing models for the measured data of resilient modulus and permanent strain was compared, and the model parameters of FAL and FAC mixes for the best fitting model were determined.
