Abstract

The mechanical response of pavement materials, known as resilient characteristics such as resilient modulus (M_R), permanent deformation (ϵ_p), is a significant input in the design of pavements. As a result, the current work is focused to investigate the above-mentioned characteristics of coal pond ash, as well as other geo-mechanical properties for its application in pavement sub-base layer. The influence of different stress levels (confining stress σ_c, & deviatoric stress, σ_d) on the resilient behaviour of pond ash was studied using repeated load triaxial (RLT) experiments. The test findings show that increasing stress levels resulted in a minor improvement in the resilient behaviour of pond ash. In addition, the obtained M_R and ϵ_p values are validated using existing mechanistic-empirical prediction models.
