Product Description

Product Description

Asphaltic Plug Joint – Accommodate up to 50 mm movement
    Asphaltic plug joint (also referred to as TST bridge joint) for movements up to 50 mm is a simple bridge expansion joint filled with asphalt. TST (crushed stone) elastic material is a special type of elastic-plastic material with high viscosity. Being heated sufficiently to melt, it can be poured into gravel and will be shaped into asphalt concrete form after molding to bear vehicle load.

    Asphaltic plug joint can simultaneously give attention to some opposing performance requirements. For example, it can perform well in both high and low temperature (-25°C – 60°C), both permeability and viscosity. As a result, asphaltic plug joint can be used for wide temperature region to prevent vehicle-jumping at bridgehead. And bridge can be opened to traffic after two hours of construction.

Material

    Main materials: TST modified asphalt (polymer-modified asphalt, softening point ≥80℃), basalt or diabase stones (size 6-12mm, crushing value ≤20%), special adhesive and composite additives.

    Modified asphalt and stones are mixed at mass ratio 1:4-1:6 to form high-elastic-plastic composite material. The material exhibits excellent viscoelasticity, aging resistance and high-low temperature stability.

Process
Deck grooving (width 30-50cm, depth 10-15cm) → groove cleaning → applying special adhesive → filling TST mixture → vibrating and compacting → surface leveling → cooling and curing → opening to traffic. Construction temperature 5-35℃, on-site mixing without prefabrication.

Features

*High elasticity: TST bridge joints can adapt the load deformation and vehicle load well.
*Good performance: TST bridge joints have good low-temperature flexibility and high-temperature stability.
*Easy to construct: TST bridge joints can be installed easily and conveniently without blocking traffic.
*Open to traffic quickly: Bridge can be opened to traffic in two hours after TST bridge joints are installed. If cooling is accelerated, the bridge can be open to traffic in an hour.
*Shock-absorbing: TST bridge joints can absorb vibration of vehicle impact and make cars go smoothly.
*Long service life: Being strict accordance with the requirements of the production and installation of expansion joints, TST bridge joints generally have a longer service life.
*Low cost & high cost-effective.
