Bridge deck pavement surface layer structure and maintenance construction method
The invention discloses a bridge deck pavement surface layer structure and a maintenance construction method. The structure comprises a bridge deck concrete pavement layer and is characterized in that the bridge deck concrete pavement layer is coated with a bond waterproof layer with ester adhesives as primer, and a colloidal concrete pavement layer formed by blending a curing agent, polyurethane and aggregate is laid on the bond waterproof layer; and an anti-sliding layer is arranged on the colloidal concrete pavement layer. The structure has the beneficial effects that good integrality and waterproofness are achieved, it is ensured that a whole bridge deck is waterproof and free of water seepage, and therefore the waterproof effect is achieved; the good high-temperature-resisting performance is achieved; high wear resistance is achieved, and wear resistance of the structure is ten times that of common cement concrete; and good pressure resistance and the good bending resistance strength are achieved, the repeated effect of loads of a high-flow vehicle can be resisted, and it is ensured that the bridge deck is free of damage to grooves, cracks and the like. According to the construction method, the requirement for the construction environment condition is not high, no special construction tool is needed, no strict technological requirement is needed, and the engineering cost is relatively low.
