Gussphalt expansion joint

Construction in less than 50m of high-extension roads, bridge roads, underground roads, and other constructions with little of expansion section. also constructed in such a way that rapid construction and unification with the road surface provide no impact, no noise, and method for improving the durability of structures.

secondary pave of guss joint mixture minerals, pave guss joint liquid, first pave of guss joint mixture minerals, Support plate, back-up material, Asphalt, Concrete

Materials and method
Waterproof : Expansion joint leak protection
Durability : Durability due to protecting shock
Driveability : Good driveability with road surface and continuity
Maintenance : Brief repair
Open traffic : After 1.5~2 hours of construction, allow traffic to pass.
