For this reason, the pavement concrete and deck concrete should be constructed at the same time but not separately. There is a concern of stripping due to bridge vibration, impact of vehicles, and rainwater permeation. If casted separately with slab concrete, the pavement concrete will be vulnerable to drying shrinkage crack because of their relatively thin thickness. On the other hand, the asphalt pavement requires less curing time and has lighter weight, easy repair or replacement, but easy to get aging and deform.Ī cement concrete pavement shall be constructed simultaneously with the slab concrete in order to form an integral structure. Cement concrete pavement has advantages like less expensive, wear-resisting, suitable for high-traffic bridge, environmental sustainability, durability, and requires less repair and maintenance over time, but requires longer curing time. Weiwei Lin, Teruhiko Yoda, in Bridge Engineering, 2017 5.3.2 Classifications of Bridge PavementĬement concrete pavement and asphalt pavement are most often used pavement method in bridge structures.
