Abstract
Various studies have shown that replacement of natural aggregate by crushed waste glass on the performance of asphalt concrete pavements. This study was intended to investigate the effect of using cullet asphalt concrete aggregate, derive the maximum allowable percentage and evaluate the economic advantage. Crushed glass with different percentages by total weight of the mixture was used in the study. Cleaned and crushed, waste glass resulted from glass bottles has been added to the asphalt mixture using a gradation of (0/4.75) mm. Marshall Method was used to determine the Optimum Binder Content (OBC) and to evaluate the properties of the glasphalt mix. Using the different glass content at their respective optimum asphalt content, specimens were prepared to investigate moisture susceptibility of asphalt mixtures. The Marshal Immersion test method was adapted to determine the moisture effect of mixtures. In total, 130 samples were prepared, 100 of which have been used to determine the OBC for each glass content, and the rest have been used to find out the moisture susceptibility of different percentages of crushed waste glass in the asphalt mixture. The results of the experiments (Marshall Stability, flow, specific gravity & air voids) are consistent to the local and international specifications, except the marshal stability reduction at 20% replacement rate. Crushed waste glass can be used in asphalt binder course with the maximal size of 4.75mm and the optimum replacement 15% glass.
