Product Description

Overview

Principles of Construction

TST seamless expansion joint is a bridge expansion joint technology suitable for various climatic conditions, made of specially made high viscosity elastoplastic materials.
The basic method of TST seamless expansion joints is to replace the narrow strip of bridge deck pavement layer above the bridge joint with a highly elastic special asphalt mixture. This high elasticity mixture of special asphalt and stone can absorb the displacement of bridge deck caused by temperature and traffic load, ensuring that the surface will not crack or be damaged. It can be used in various environments in different regions.
 

 

Product advantages
The product advantages of TST seamless expansion joints are mainly reflected in high elasticity recovery, excellent thermal performance, convenient construction, fast opening of traffic, good comfort, and economic benefits.
1. High elastic resilience: TST seamless expansion joints can adapt to repeated temperature and load displacements, with very high elastic resilience, effectively absorbing various deformations and vibrations, and high damping, which is conducive to seismic reduction of bridges.
2. Excellent temperature performance: Its low-temperature flexibility and high-temperature stability are both very good. It will not become brittle at -40 ºC and will not flow at 80 ºC, making it suitable for all climate zones in China.
3. Construction convenience: TST seamless expansion joint construction does not require the installation of specialized expansion joint components, nor does it require pre embedded anchoring steel bars at the beam end, making it convenient and fast. A skilled construction team can lay longer expansion joints every day and carry out half width construction without blocking traffic.
4. Fast opening of traffic: The seamless expansion joint adhesive can be opened to traffic within two hours after installation. If water is sprayed to accelerate cooling, traffic can be opened within one hour, greatly shortening the construction period and improving the efficiency of road use.
5. Good comfort: TST seamless expansion joints are directly laid flat at the bridge joints, forming a continuous body with the front and rear bridge deck or road pavement. The bridge deck is smooth and seamless, driving is smooth and comfortable, without noise, and with low vibration.
6. Good economic benefits: TST seamless expansion joints are low-cost, durable and easy to maintain, with low replacement frequency, and have significant economic and social benefits
 

Specification

Product Name	TST seamless bridge expansion device(TST)
Working Principle	The working principle of TST seamless expansion joint is to heat and melt the specially made elastic-plastic main material, pour it into the heated crushed stone, and form the "TST bridge joint elastic-plastic body", which is used to absorb the displacement of the bridge slab caused by temperature and traffic load, ensuring that the surface of the road will not crack or be damaged. Specifically, the filling material of TST seamless expansion joints fully exhibits elasticity when subjected to instantaneous loads and high-frequency vibrations, can absorb various deformations and vibrations, has high damping properties, and is beneficial for bridge seismic reduction. When temperature changes cause the bridge to contract, under the low-frequency buffering effect, the elastic-plastic body will fully exhibit plasticity and adapt to the expansion and contraction deformation of the bridge. The crushed stone supports the vehicle load, while the TST-Z special adhesive ensures interface strength, connecting the joint with the bridge deck pavement and providing good sealing and waterproof performance. In addition, TST seamless expansion joints are not only suitable for areas with small temperature differences, but also for areas with large temperature differences, and have a wide range of applicability.
Product Structure	The product structure of TST seamless expansion joint is mainly composed of specially made high viscosity elastoplastic material (TST material) and crushed stone. The heated and melted TST material is poured into the heated crushed stone to form an expansion joint structure that can withstand vehicle loads and adapt to longitudinal creep of the beam.
Applications	TST seamless expansion joints are mainly used for joint treatment of high-grade road surfaces such as highways, urban roads, airport runways, and bridges, especially in road sections that need to withstand large amounts of traffic, drastic temperature changes, and frequent heavy loads. TST seamless expansion joints have become the preferred solution for solving problems such as cracking, water seepage, and vehicle noise at road joints due to their excellent adhesion, elasticity, and weather resistance. In bridge engineering, it is widely used in the renovation of old bridges and the treatment of longitudinal joints in bridge bodies. Its seamless design makes the bridge deck smoother, effectively improving the comfort and safety of driving.
Product parameter adjustment	Production can be carried out according to the drawings, or customized processing can be carried out according to customer needs
Program Design	Design separately according to different usage projects
