RENEWAL METHOD FOR EXISTING ROAD, AND RENEWED ROAD
PROBLEM TO BE SOLVED: To provide a renewal method for an existing road that curtails a period needed for the renewal work of the existing road, along with a road renewed by the renewal method.SOLUTION: A renewal method for an existing road is for renewing an existing road 10 having a reinforced concrete floor slab 2 installed on two or more steel main girders 1. The renewal method for an existing road includes: a first step in which only a portion 4 of the floor slab 2 lying on the main girder is left as is, and the other portions are removed; and a second step in which a new floor slab block 6 having two or more recesses 6a on an undersurface is installed such that each of the recesses 6a is placed on the portion 4 on the two or more main girders, and the installation process of the floor slab block 6 is repeated in a direction of extension of the road, for constructing a renewed road 20.SELECTED DRAWING: Figure 4
【課題】既設道路の更新施工に要する工期の短縮を図ることのできる既設道路の更新施工方法と、この更新施工方法で更新施工された道路を提供すること。【解決手段】二以上の鋼製の主桁１上に鉄筋コンクリート製の床版２が設置されてなる既設道路１０の更新方法であって、床版２のうち、主桁上の部分４のみを残置し、他の部分を撤去する第一のステップ、下面に二以上の凹部６ａを備えた新設の床版ブロック６を、それぞれの凹部６ａが二以上の主桁上の部分４に嵌るようにして設置し、この床版ブロック６の設置を道路の延伸方向に繰り返して更新施工された道路２０を施工する第二のステップからなる、既設道路の更新施工方法である。【選択図】図４
