TST Expansion Joint Product Description TST bridge expansion joint is also called seamless expansion joint adhesive material. It is a kind of asphalt filled bridge expansion joint. It is a kind of bridge expansion joint which was developed by England in 70s. It is also called seamless expansion joint adhesive. Its basic approach is to replace a narrow strip of bridge deck pavement on a joint to a high elastic special asphalt mixture. The mixture of high elasticity special asphalt and stone can absorb the displacement of the bridge deck due to the temperature and traffic load, and ensure that the surface can not crack and damage. These seamless adhesive materials are capable of taking into account both high temperature and low temperature, penetration and viscosity, which are not only applicable to a single temperature region, but also to regions with large temperature differences.
Characteristic:
1,TST resilient resilience is very high: it can adapt to repeated temperature and load displacement.
2,Low temperature flexibility and high temperature stability are excellent: it will not become brittle at -40 degrees centigrade and will not flow at 80 degrees centigrade. Therefore, it can be applied to all climate zones in china.
3,High temperature adhesion: construction can be firmly bonded with the existing road, at room temperature is not sticky at all, and will not be taken away after cooling.
4,Convenient and flexible construction, skilled construction team (8-10), 30 meter GTF TST expansion joint every day, and can not block the traffic under the condition of half construction.
