TRANSITION SLAB BETWEEN THE ABUTMENT AND THE DECK OF A BRIDGE WITH EXPANSION AND CONTRACTION JOINTS HAVING A LONG SERVICE LIFE, AND METHODS FOR ABSORBING THE EXPANSION AND CONTRACTION MOVEMENTS OF THE DECK OF A BRIDGE

摘要

The present invention relates to a transition slab connected at the ends thereof to a deck compression slab and to an anchoring. The mentioned transition slab absorbs the expansions of the deck by means of the compression of sheets of polymer, elastomer or the like arranged in parallel and integrated in said transition slab, perpendicular to the longitudinal direction of the road.;The transition slab absorbs the contraction movements of the deck by means of expansion, due to the summation of crack openings in induced cracks and the spacing between the crack planes.;Said crack planes are forced by forms made of wood, polymer or the like arranged in parallel, spaced apart and integrated in the transition slab.
