RUBBER CONCRETE FOR ROAD BRIDGE AND CONSTRUCTION METHOD THEREFOR, AND EXPANSION DEVICE USING RUBBER CONCRETE FOR ROAD BRIDGE

摘要

PROBLEM TO BE SOLVED: To provide rubber concrete that is adapted to an expansion device for road bridges and exhibiting literal elasticity, namely deformation properties and reconstruction properties, and a construction method therefor, and to provide the expansion device using the same.;SOLUTION: Rubber concrete for road bridges is constituted by using a low hardness rubber material curing under the ordinary temperature and aggregate, in which the cured rubber hardness of the low hardness rubber material is in a range of Hs=5-50 degrees. Also, an expansion device using the rubber concrete for the road bridges is constituted by including: a dead space between the surface of adjacent floor slabs 11, 12 and the surface of the side surface of pavements 13, 14 constructed on the floor slabs; the rubber concrete constructed in the dead space, constituted by a low hardness rubber material curing under the ordinary temperature and aggregate, and in which the cured rubber hardness of the low hardness rubber material is in a range of Hs=5-50 degrees; and adhesive means for joining the rubber concrete coming into contact with the floor slab and the pavement by adhesives.;COPYRIGHT: (C)2015,JPO&INPIT
