An expansion joint system which is provided to accommodate forces applied to highway construction during normal changes in ambient conditions, and which is also designed to withstand seismic forces and vehicular forces, which may be applied in transverse and longitudinal directions. The system includes spaced-apart transverse vehicle load bearing members which are placed in a gap defined between adjacent sections of highway construction, longitudinally extending support members positioned beneath the load bearing members, means embedded within the adjacent roadway sections that control longitudinal, transverse and vertical movement, and a mechanism for controlling the spacing between the transverse load bearing beams. Preferably, this mechanism maintains a substantially equal distance between the transverse load bearing beam members.
An expansion joint system for roadway construction wherein a gap is defined between adjacent first and second roadway sections, said expansion joint system extending across said gap to permit vehicular traffic, said expansion joint system comprising:
