To explore the effect of acid rain corrosion on the cohesion performance of asphalt and its mechanism, graphene oxide (GO) was used to modify epoxy asphalt and 70# base asphalt, TAFPACK Super (TPS) high viscosity asphalt and epoxy asphalt were used as the control group, the periodic dry–wet cycle immersion test was used to simulate the acid rain environment to study the effect of acid rain on the physical properties, composition, cohesion and adhesion between different asphalt binders and aggregates. Furthermore, combined with aging test, the ...
