Q:What is the principle of TST expansion joint ? &©|160;&©|160;&©|160;
A:The so-called "elastic joints" is a kind of viscoelastic material to do the joints, so that the joints have a certain elastic deformation to adapt to the deformation of the structure.

Q:What are the characteristics of TST expansion joint ?
A:The following are the characteristics of TST expansion joint :
1.TST is a kind of high visco elastic plastic material.It is elastic and plastic at room temperature.After high temperature melting, it can be poured into the gravel,and like asphalt concrete after molding.It can bear the load of the vehicle,and it is elastic.
2.Simple structure.TST crushed stone paved directly at the bridge joints,And the formation of the continuous bridge deck pavement,and bridge deck level seamless.The elastic joints can absorb various aspects of deformation and vibration, smooth running, comfortable, no noise, vibration.
3.Convenient and quick construction.After cooling,there can be open to traffic.When the expansion joint needs to be replaced,there can be half edge construction.The traffic on the busy road is not interrupted.
4.Joint and bridge deck pavement,good sealing and waterproof,And the cost is low and durable.

Q:What are the installation methods&©|160;&©|160;of TST expansion joint ?
A:The following are the installation methods&©|160;&©|160;of TST expansion joint :
1.Clean the notch, so as to achieve the design of width and depth.Clear steel bar&©|160;which interference displacement box buried,and the opening of the reserved hole must be greater than the width of the installation of the expansion joint.
2.Check whether the gap between the vario |
