SURFACE-COMPACTED CONCRETE PAVEMENT, AND CONSTRUCTION METHOD OF SURFACE-COMPACTED CONCRETE PAVEMENT
PROBLEM TO BE SOLVED: To provide a surface-compacted concrete pavement or the like that offers high compaction property.SOLUTION: A surface-compacted concrete pavement comprises a mortar layer laid on a base course and a concrete layer laid on the mortar layer, and the mortar layer is of a mortar hardened body with a sinking depth of a weight below of up to 6 mm. The sinking depth of the weight refers to a depth (mm) when the weight has completed sinking after being placed on an evenly laid fresh mortar layer of a thickness of 25 mm, the weight being of a columnar or a square columnar shape with each of edge surfaces measuring 283 to 346 mmin area (the areas of both edge surfaces being equal), and having a mass of 500±3 g. A construction method of the surface-compacted concrete pavement is such that after laying mortar of the sinking depth of the weight of up to 6 mm on the base course, concrete is laid and compacted on the mortar.SELECTED DRAWING: Figure 1
【課題】締固め性に優れた転圧コンクリート舗装等を提供する。【解決手段】路盤の上に敷設されたモルタル層と、該モルタル層の上に敷設されたコンクリート層からなる転圧コンクリート舗装であって、前記モルタル層が、下記錘の沈下深さが６ｍｍ以下のモルタルの硬化体である、転圧コンクリート舗装とする。錘の沈下深さは、形状が円柱又は角柱であって、該円柱又は角柱の各端面の面積が２８３〜３４６ｍｍ２（ただし、各端面の面積は等しい。）であり、かつ質量が５００±３ｇである錘を、厚さを２５ｍｍに敷き均したフレッシュ状態のモルタルの上に載せ、該錘の沈下が終了した時点において該錘が沈下した深さ（ｍｍ）とする。また、路盤上に、前記錘の沈下深さが６ｍｍ以下のモルタルを敷設した後、該モルタルの上にコンクリートを敷設して転圧する、転圧コンクリート舗装の施工方法とする。【選択図】図１
