Pavement is preformed neoprene seals (neoprene), which meets or exceeds ASTM standards existing extrusion compounds. They are compressed and kept in contact with the joint walls, while the temperature changes during the expansion and contraction of the concrete pavement, prefabricated pavement seal has been shown for many years to maintain lasting and effective. Prefabricated pavement seals are used for the highway, the main sealing system airport apron and runway concrete pavement bricks, prefabricated pavement seal conforming to ASTM standards. They also adopted the construction design institutes and organizations as an effective, long-lasting concrete pavement joint sealing solutions。
