Moisture Susceptibility of Nano-Al2O3 and SiO2 Modified Asphalt Mixtures
The aim of the study is to evaluate the performance of hot mix asphalt (HMA) against moisture with nano-materials according to Superpave mix design procedure. In this study, bitumen is modified by silica nano-powder (SiO2NP) and aluminum oxide (Al2O3) nano-particle. Nano-materials are mixed with base bitumen at contents of 0.3% and 3% by nano-silica and aluminum oxide and 0.5 and 5% nano-silica and aluminum oxide by weight of bitumen, respectively. HMA is prepared with nano-modified bitumen at optimum binder contents (OBC). Moisture susceptibility of modified HMA is evaluated according to modified Lottman test procedure. OBCs are increased by modification. HMA samples modified by 0.3% SiO2 and 3% Al2O3 is determined as high resistive to moisture compared to other mixtures.
