Asphalt filled bridge expansion joint（made in china）

TST seamless expansion joint bonding material
Product introduction:
Seamless expansion joint is a kind of asphalt filled bridge expansion joint. It is a bridge expansion joint developed by Britain in the 1970s.The basic method is to replace the bridge deck with a narrow strip of the seam with a high elastic special asphalt mixture.The mixture of high elastic special asphalt and stone can absorb the displacement of the bridge panels resulting from temperature and traffic load, and ensure that the surface layer does not crack.Seamless adhesion is able to simultaneously balance high temperature and low temperature, permeability and viscosity of these opposing performance requirements, not only applicable to temperature single area, but also applicable to the area with large temperature difference.
Product features:
Resilience is very high;Can adapt to repeated temperature and load displacement;Low temperature flexibility and high temperature stability are very good;Not brittle when to 40 ℃, 80 ℃ when not flow;Therefore, it can be applied to all climate zones in China.High temperature adhesion;The construction can be firmly bonded to the existing road surface, which is not sticky at all, and will not be taken away after cooling.The construction is convenient and flexible: the skilled construction team (8-10 people) can stretch the TST expansion joint every day, and can construct half of the construction without blocking the traffic.Open traffic quickly: two hours after the installation of the seamless expansion joint, the traffic can be opened, and the traffic can be opened after an hour.The service life is long: it is strictly according to the process requirement to install seamless expansion joint, its life is about twice as long as normal modified asphalt pavement.The comfort is very good: the seamless expansion joint can absorb the vibration of the vehicle fully, the vehicle is comfortable and smooth.The economic benefits are good.Low cost.
