ABSTRACT:
A seal and cover for expansion joints in roadways and bridges comprised of a block of elastomer having grooves extending downwardly from its top surface to allow for expansion and contraction. A metal plate is secured to the top of the elastomer block to protect the block and help carry the weight of vehicles over the joint. The plate may also have grooves in its top surface to reduce the likelihood of vehicles skidding as they cross the joint.
