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

A transition slab connected at opposing ends to a deck compression slab and to an anchoring. The transition slab absorbs the expansions of the deck by means of compressing sheets of polymer, elastomer or the like, that are arranged in parallel spacing and integrated in the transition slab to be oriented perpendicular to the longitudinal direction of the road. The transition slab absorbs the contraction movements of the deck limited expansion due to the summation of crack openings in induced cracks. Crack planes are created by forms made of wood, polymer or the like arranged in parallel, spaced relation within the body of the transition slab.
