Abstract

Curved bridge deck pavement materials are easy to be damaged due to their complex stress conditions. Hence, the application of a high-viscosity modified asphalt mixture in curved bridge deck pavement is studied in this paper. Firstly, the severity of pavement diseases on curved bridge decks was introduced and compared with the deck pavement diseases in straight sections. Then, compared with SBS-modified asphalt mixture SMA-13, the advantages of high-viscosity modified asphalt mixture HM-SMA-13 in resistance to deformation, water damage, shear deformation, and fatigue were analyzed. The results show that HM-SMA-13 has 1.6 times the high-temperature deformation resistance, 1.2 times the shear deformation resistance, 1.1 times the low-temperature performance, 1.05 times the water stability, and 7 times the fatigue resistance of the SMA-13 mixture. Finally, HM-SMA-13 was applied to the curved bridge deck pavement. After one year of operation, slight rutting and cracking appear on the bridge deck pavement, which indicated that HM-SMA-13 is a suitable material for curved bridge pavement.
