Abstract:
1. 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: a plurality of transversely extending, spaced-apart, load bearing members having top surfaces and bottom surfaces, wherein said top surfaces are adapted to support vehicular traffic; at least one elongated support member having opposite ends extending longitudinally across said expansion joint from said first roadway section to said second roadway section, wherein said at least one support member is positioned below said transversely extending load bearing members; at least one first means for accepting an end of said at least one longitudinally extending elongated support member, wherein said first means for accepting includes means for substantially restricting transverse movement within said at least one first means for accepting, but permitting longitudinal movement within said first means for accepting; at least one second means for accepting an end of said at least one longitudinally extending elongated support member, wherein said second means for accepting include means for substantially restricting longitudinal movement within said second means for accepting, but permitting transverse and vertical movement within said second means for accepting, wherein said at least one elongated support member has one end located within said first means for accepting and the opposite end located in said second means for accepting; and at least one expansion and contraction means for controlling the spacing of said load bearing beams relative to one another comprising pivotably attached arms that are movably engaged with said load bearing members.
