Abstract:The unbound granule material (UGM) is widely applied as the base/subbase layer in pavement engineering. The poor quality of UGMs mainly result in differential settlement and fatigue failure of UGMs. This paper presents a laboratory investigation on the influence of the maximum particle size (MPS) of aggregates on the resilient modulus (MR) of UGMs. The repeated load triaxial tests were performed under different stress levels. Three nonlinear models were compared to describe the mechanical behavior of UGMs. The… Show more
