摘要： PURPOSE: An LMC construction method for concrete floor slab bridge pavement is provided to simplify the construction progress, to increase adhesion of old and new concrete, to suppress crack, and to secure durability and flatness. CONSTITUTION: An LMC construction method for concrete floor slab bridge pavement comprises steps of cutting bridge surface and cleaning scraps of concrete, oil, and adsorbed foreign materials(S10); maintaining a humid condition(S20) by covering slab concrete with a humid blanket and then watering the humid blanket; installing a concrete roller paver rail for movement of a concrete roller paver(S30); maintaining a surface dry-saturated condition by watering foreign materials and covering the bridge surface with vinyl, to prevent incoming of foreign materials(S40); producing LMC(S50); executing blooming work of preventing LMC from being dried till paving(S60); constructing LMC pavement and shoulder(S70); executing tinning work of finishing roughened surface by a tinning machine(S80); applying curing agent(S90); covering a curing blanket for protection from the external effects(S100); and executing curing by rolling up the curing blanket and executing air dry curing for at least seven days(S110).

摘要： PURPOSE: A reformed concrete composition for bridge deck pavement and paving method is provided to give excellent waterproof and adhesion properties, and reduce chlorides penetration. CONSTITUTION: The reformed concrete composition comprises synthetic 17-22w/w% of rubber-based latex(solid content:45%), 11-14w/w% of cement 35-40w/w% of sand, 25-27w/w% of gravel and 3-5w/w% of acrylic-based emulsion copolymer. The bridge deck pavement method contains: removing pollutants such as dust, lubricant and solvent oil, followed by eliminating aggregates; keeping wet for 3-4days; preparing saturated surface condition by blasting and vacuum pump; paving with above composition; texturing, then spreading a film curing agent; wet-curing by covering a polyethylene film for 72hrs.
