Rubber seal strip Expansion Joints for bridge:
EPDM has better weather, ageing, ozone, and temperature resistance than Neoprene.
Neoprene, on the other hand, has better oil –swell and tensile strength characteristics.
The use of both caoutchouc mixtures has been properly proven through practice.
Expansion joints are integrated with bridge decks in order to accom modate the relative movement between the structure’s segments, as well as the movement between the superstructure itself and support abutmets. Such movements is the result of thermal expansion and contraction, creep and shrinkage of concrete, substructure settlement, live dynamic loads and other causes. |
As a result of further advanced research and development, AAA’s single cell joints are manufactured using high quality steel rails that ensure a watertight interlocking mechanism by using a neoprene seal. What makes AAA’s Single Cell Joints so unique is the additional protection it prodives to underlying structures such as abutments.
