Abstract

In order to decrease the agglomeration of carbon nanotubes (CNTs) and enhance the interaction between CNTs and epoxy asphalt (EA), CNTs were modified by epoxy resin (ER) after treated with mixture acid, and then CNTs-EA was synthesized via mechanical stirring method. Experimental results confirmed that ER was decorated on the surface of CNTs. Moreover, the softening point and anti-ultraviolet aging of matrix asphalt were significantly improved by introducing modified CNTs, which increased about 48.7% for softening point and the variety ratio of UV aging (UAI) value was close to 1. The enhancement is mainly attributed to the excellent property of CNTs and the effective synergistic effect between CNTs and ER.
