Design of flexible pavements for low volume roads is a challenging task to eliminate premature failures. This is especially due to the design procedures followed in India. Generally the pavement thicknesses are obtained by considering only the subgrade properties. Hence there is a need to revisit the design methodology by considering damage analysis of these pavement designs. Besides, reclaimed asphalt pavement (RAP) material along with virgin aggregates (VA) is a widely preferred option to reduce the cost and to incorporate sustainability in the pavement construction. This study focuses on developing a design chart for selecting thickness of base/subbase layer for low volume roads when 80% RAP material and 20% VA mixture treated with different dosages of fly ash is used as base/subbase material based on damage analysis. The resilient modulus obtained from repeated loading triaxial test is required for performing damage analysis in KENLAYER to obtain the desired pavement thickness which is calculated corresponding to a design life of 10 years. In addition, the strains developed in the pavement layers due to wheel loading obtained from KENLAYER is compared with that obtained from indigenous Indian road congress (IRC) IITPAVE software.
