pavement maintenance composite seal epoxy asphalt laboratory evaluation pavement condition simulation steel bridge deck pavement
In order to improve the surface performance of epoxy asphalt pavement(EAP)for steel bridge deck, an epoxy asphalt chip seal(ECS)covered by a cationic emulsified asphalt fog seal(i.e., fog-sealed chip seal)is proposed and a laboratory study is conducted to design and evaluate the fog-sealed chip seal. First, the evaluation indices and methods of the chip seal on steel bridge deck pavement were proposed. Secondly, the worst pavement conditions during the maintenance time were simulated by the small traffic load simulation system MMLS3 and the short-term aging test for minimizing the failure probability of chip seal. Finally, the design parameters of fog-sealed chip seal were determined by the experimental analysis and the performance of the designed fog-sealed chip seal was evaluated in the laboratory. Results indicate that the proposed simulation method of pavement conditions is effective and the maximal load repetitions on the EAP slab specimen are approximately 925 300 times. Moreover, the designed fog-sealed chip seal can provide a dense surface with sufficient skid resistance, aggregate-asphalt adhesive performance and interlayer shearing resistance.
