Pavement of bridge surface and continuous pavement method of bridge surface

摘要

PURPOSE:To obtain a pavement body which causes less plasticity deformation and excels in durability in the pavement body which can be provided continuously on both sides of expansion and contraction play of a bridge body on a road bridge. CONSTITUTION:A slide layer which can slide in the horizontal direction for a bridge body is provided on the bottom of a pavement body. The slide layer consists of a slide face forming layer 3 like sheet and a slide sheet 4 which are overlapped to allow slide on the contact face. A net body 6 which has comparatively fine mesh is provided on the slide layer, and further, a stress transmission member 7 which consists of a member like net which has comparatively large mesh and through which all aggregate can pass is provided on it. The stress transmission member 7 is combined with the net body 6 by line material or pressing metal fittings which have a section like plate which is arranged almost horizontally are fixed and imbedded by asphalt mixture to form the pavement body. Since the stress transmission member 7 is combined with the net body 6 or the pressing metal fittings are fixed, it is possible to prevent lifting in a substrate 8 consisting of asphalt mixture.
