Evaluation the Effect of Glass Wastes and Metal Oxides Nanoparticles on the Stripping Strength of Asphalt Mixtures
One of the degradable industrial materials is glass wastes. Many methods have been utilized to mitigate the destructive environmental effects of glass wastes. One of the important methods is to utilize them in different industrial sectors. Recently, the use of this material in pavement industry as a component of asphalt mixture has attracted researchers’ attention. One of the problems in the application of glass wastes in asphalt mixtures is the moisture sensitivity of asphalt mixtures. In this study, asphalt mixtures fabricated using 0, 5, 10, 15 and 20% glass wastes as fine aggregates. A 60/70 binder was selected and it was modified by two anti-striping Nano materials named Nano aluminum oxide and Nano iron oxide. In order to evaluate the performance of mentioned additives, moisture susceptibility test based on AASHTO T283 are conducted. The results of this study showed that the use of glass wastes increases the moisture susceptibility of asphalt mixtures. Higher glass content increases the moisture susceptibility of asphalt mixtures. Also, the use of mentioned additives led to an improvement in the properties of asphalt binders. It decreases the acidic properties of modified binders. Hence, the cohesion between asphalt binder and glass is increased and it provides a better performance against moisture damage in comparison with base materials.
