ASPHALTIC PLUG JOINT

Asphaltic plug joint for movements up to 40 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. The most advantage of  Asphaltic plug joint is that the bridge can be opened to traffic after two hours of construction.
