Experiment Researches on the Performance of Chemical Network-forming Modified Asphalt Mixture

摘要

Chemical network-forming modified asphalt(CNMA) is a mixture in which the chemical reactions take place among the polymer molecule chains dispersed in asphalt by the addition of active agent, thus, the strong tri-dimension space net-structure are formed by the chemical bonds. The net-phase-structure is made of asphalt and polymer in a way of perforating each other. Six kinds of bitumen are selected to evaluate the performance of the CNMA by the indoor experiments in this paper. Experiment researches indicate that the performance of the CNMA is more excellent than other modified asphalt, including PE, SBS and imported modified asphalt.
