In this present research, series of laboratory model tests were carried out using unreinforced Wet Mix Macadam (WMM) and reinforced RAP + WMM (50:50) placed on soft marine clay bed to study its load settlement characteristics. Polymer geogrid, Polymer geocells, Bamboo geogrid and Bamboo geocells were used as reinforcements in mixture of RAP + WMM (50:50). Model test on WMM was carried out without reinforcement as the same is generally used as base course of conventional flexible pavement. Whereas, model tests on mixture of RAP + WMM (50:50) were carried out with geogrid and/or geocell reinforcements (Polymer/Bamboo) to compare it with that of unreinforced WMM. Load bearing capacity of reinforced RAP + WMM (50:50) were observed to be more than that of unreinforced WMM. Improvement in load bearing capacity of RAP + WMM (50:50) as compared to that of unreinforced WMM was observed to be 39% when reinforced with Bamboo geogrid + Bamboo geocells and 174% when reinforced with Polymer geogrid + Polymer geocells. Due to this improvement in load bearing capacity of reinforced RAP + WMM (50:50) in comparison to that of unreinforced WMM, it could be used in base course of flexible pavement construction. Cost analysis based on preliminary model tests results indicate that alternative pavement options with Polymer / Bamboo (geogrid / geocell) reinforced RAP + WMM (50:50) as base is cost effective as compared to that of conventional pavement with granular base (WMM).
