Asphaltic Expansion Joint (Seamless expansion joints adhesive material), also known as: "TST bridge expansion joints", "TST expansion joints adhesive material", which is a bridge expansion joint installation method developed by United Kingdom at the seventies. This is one type filler bridge expansion joint made by asphalt. Its basic construction principle is a narrow range deck pavement on seam replaced with a special high - elastic asphalt mixture materials. This high elasticity mixture of special asphalt and stone can absorb the bridge deck displacement produced by Load effect from temperature and traffic, while ensuring that the surface will not crack damage. Seamless stretchable adhesive material can be taking into account both high temperature and low temperature, penetration and viscosity of these opposing performance requirements, not only for single temperature areas, but also for areas with large temperature difference.
