MODIFIED CONTINUOUSLY REINFORCED CONCRETE PAVEMENT STRUCTURE USING PARTIAL REBAR AND CRACK INDUCTION

摘要

The present invention relates to a continuously reinforced concrete pavement (CRCP) structure includes: continuous rebar continuously arranged inside a concrete pavement layer in a longitudinal direction; multiple partial rebar interposed between the adjoining continuous rebar in a longitudinal direction of the continuous rebar to be separated at constant intervals; and a crack inducing unit formed at a position where the partial rebar are arranged to be parallel inside the concrete pavement layer. The crack inducing unit includes: an upper part made of concrete, arranged to be perpendicular to a direction where the continuous rebar are arranged inside the concrete pavement layer, having a triangular cross section, and having an inclined surface on one lateral surface; a lower unit coming into contact with the other lateral surface of the upper unit ad having a rectangular cross section; and attachment preventing layers formed on the other lateral surface of the upper unit and the other lateral surface of the lower unit. The partial rebar penetrates through the lower unit of the crack inducing unit, thus both ends of the partial rebar are exposed. Transverse rebar are embedded in the lower unit of the crack inducing unit to be perpendicular to the direction where the continuous rebar are arranged. The continuous rebar are arranged to be supported by the transverse rebar exposed through a groove of the lower unit. The purpose of the present invention is to provide a modified CRCP structure capable of sufficiently controlling cracks while preventing the excessive arrangement of the continuous rebar.;COPYRIGHT KIPO 2016
