Best price Asphalt expansion joint for bridge deck
asphaltic plug bridge expansion joint is composed of a blend of asphalts, vegetable fibers, and mineral fillers formed under heat and pressure between two asphalt-saturated liners. It is waterproof, permanent, flexible, and self-sealing. It can fully absorb the bridge deck's vibration shock which come from vehicular traffic,and is effective in reducing the bridge cracks,so that make it comfortable and smooth when vehicles cross. Ensure construction quality through control the Process of construction technology on expansion joints. It is heated to melt, and filled into heated madadam, to form into TST bridge joints. The madadam is for bearing the vehicles, and TST-Z sealant is for interfacial strength.
Features:
--directly tiled in bridge joints, it junction well with front and back bridges / roads. The bridge deck is smooth and seamless.
So diving is more comfortable, noiseless, small vibration. What's more, it is easy to maintenance, clean and snow removal.
--simple structure, no need to install expansion devices and anchor bar. the construction is quick and easy.
--It can absorb vibration and deformation, and is high damping. It benefits for bridge shock absorption, and can meet the needs of bridge contraction and deformation.
--good sealability and chemical resistant.
--lost cost, durable and less maintenance.
Application field:
suitable for highway bridges, viaduct, urban overpass etc, in districts of temperature -25℃ to 60℃,
movements ≤50mm
