Elastomer Expansion Joint

The TST filling joint is an innovative seamless elastomeric solution. After the specially formulated RS rubber is heated and melted, it is injected into the pre-heated high-quality crushed stones to form an elastomeric composite. The crushed stone framework bears the load, and the RS rubber's viscoelasticity achieves sealing and deformation. This structure directly integrates with the bridge deck pavement to form a continuous whole, achieving true "smooth and seamless" performance. Driving is extremely smooth and noise-free. The construction is extremely convenient; no complex embedded anchoring steel bars are required. It can be constructed in one lane and can be opened to traffic after cooling, significantly reducing traffic disruption. This product can absorb longitudinal, lateral, and vertical deformations and vibrations, has excellent sealing and waterproof properties, and is resistant to acid and alkali corrosion. It has significant economic benefits and is an ideal choice for urban overpasses, elevated bridges, and old bridge renovation projects with an expansion and contraction amount of less than 50mm.
