Test Research on Rubber Powder Asphalt Mixture under the Action of Temperature and Chlorine Salt

This experiment analyzes the relation between rubber power asphalt mixture and Marshall Test results under the action of the temperature and salt corrosion, by using matrix asphalt mixture and 80 mesh 10% rubber power. It carries out 18 test, considering two factors of NaCl solution solubility and soak time. The test result indicated that immersed in the NaCl solution of the matrix asphalt mixture and the rubber power asphalt mixture stability is trending downward, with the increase of immersion time; Rubber power can improve the ability of asphalt mixture for resistance temperature and salinity. According to SEM micro-analysis, NaCl solution of salt corrosion can contribute to the further damage of asphalt mixture. Keywords. Temperature; Chlorine Salt Corrosion; Rubber Powder; Asphalt Mixture
