Resilient Modulus Characterization of Unbound Granular Materials Through Laboratory Dynamic Cone Penetration Test

A prerequisite for the reliable design of low volume roads (LVRs) is the development of simple and reliable testing techniques to simulate the behavior of unbound granular materials (UGMs) under conditions similar to those that occur when subjected to traffic. Therefore, there is a need for a simple correlation method to characterize the mechanical behavior of UGM under the action of moving traffic loads. This paper discusses the results of the experimental study and statistical analysis on the resilient modulus (MR) characterization of UGMs through laboratory Dynamic Cone Penetration (DCP) test, this correlation is intended to be adopted in the of UGMs used in LVRs. The laboratory study was conducted on twenty-one UGMs samples to obtain index, strength, MR, and laboratory DCP-Dynamic Number (DN) parameters. The correlation has been achieved by correlating MR values compacted at 95% of Maximum Dry Density (MDD) with the laboratory DCP-DN values. The results show that MR values of UGMs significantly correlate with laboratory DCP-DN values and follow the power equation of MR=700×DN-0.7 with coefficient of determination value of 0.99. Furthermore, a cyclic load triaxial test was carried out on UGMs to validate the result of the MR–DN. The MR–DN relationship estimates a reasonably resilient modulus of UGMs which can be used as an input into the mechanistic-empirical (M-E) pavement design analysis of LVRs in the absence of Repeated Load Triaxial (RLT) testing facilities.
