ASPHALT EXPANSION JOINT Expansion/Contraction Control Joint
elastomeric TST bridge expansion joints
ASPHALT EXPANSION JOINT Expansion/Contraction Control Joint
asphalt bridge expansion joints, is made mainly from RS rubber and tst. 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
