| This study is to evaluate the property for the moisture susceptibility of asphalt mixtures using anti-stripping agent. Asphalt mixtures using lime, hydrated lime and liquid anti-stripping agent are evaluated through the three types of modified moisture conditioning($H_c$, V_s$, F-T). Indirect Tensile Test, that is recommended by AASHTO TP-9, which includes creep test, resilient modulus test and strength test is used to estimate moisture susceptibility. Analysis method through Energy Ratio(ER) that is proposed by Roque at University of Florida is used to evaluate moisture susceptibility and moisture resistance effects of asphalt mixtures using anti-stripping agent. As a test result, material property of asphalt mixtures was changed by moisture conditioning methods and the types of anti-stripping agent. Also, cracking resistance of accumulated moisture damage was changed by moisture conditioning methods and the types of anti-stripping agent. Based on test result, it was found that cracking resistance using Energy Ratio was differed from 10% to 30%. |
