Descriptions  Elastomeric rubber expansion joints, is also called bridge deck rubber expansion joints. It is a device relative movement between two parts of a structure. It is made mainly of natural neoprene rubber and use steel plate as skeleton for reinforcement.It is designed and manufactured using the principle of low shear modulus of rubber. It can accommodate expansion displacement by shear deformation of rubber. It featured by low lateral resistance of expansion and compression. And it benefit to bridge structure. Characteristics   Expansion joints permits thermal contraction and expansion without inducing stresses into the elements. An expansion joint is designed to absorb safely the expansion and contraction of several construction materials, absorb vibrations, and permit soil movements due to earthquakes or ground settlement. The expansion joints are normally located between sections of bridges, paving slabs, railway tracks, and piping systems. Weather changes during the year produce temperature variations that cause expansion and contraction in concrete paving slabs, building faces, and pipelines. The expansion joints are incorporated to endure the stresses. An expansion joint is simply a disconnection between segments of the same materials. In the concrete block construction, the expansion joints are expressed as control joints.
