Abstract
An expansion joint sealing system for bridging and sealing a gap located between two spaced-apart structural deck members. The expansion joint sealing system includes an elastomeric seal member and a substantially rigid plate member. The elastomeric seal member is fixedly attached to an underlying structural deck member and is able to expand and contract in the longitudinal direction in relation to the traffic direction across the expansion joint. The rigid plate is not fastened to the elastomeric seal member with mechanical fasteners or other fastening means, but is slidingly engaged with the elastomeric seal member through an elongated guide member. As the rigid plate member is not fastened to the elastomeric seal member, it is able to move along a guide member in a direction that is transverse to the direction of traffic across the expansion joint.
