CONCRETE BLOCK FOR PAVEMENT AND PAVEMENT STRUCTURE
To provide a concrete block for pavement and a pavement structure that are less likely to cause wear, chipping, and cracking of individual blocks, and are less likely to cause steps, subsidence, horizontal movement (misalignment), and rutting on an entire road surface, can maintain good road surface properties for a long period of time, and can suppress the running noise of a vehicle.SOLUTION: A cement composition comprises: a cement and powder containing a filler having an average particle size of 1/50 or more and 1/5 or less of the average particle size of the cement particles; a fine aggregate; a coarse aggregate; and water. The mass ratio of the water to the cement is 0.28 or less. A concrete block for pavement is a regular hexagon having a plane shape of an upper end surface of 50 mm or more and 380 mm or less on a side, and a prismatic shape having a thickness of 50 mm or more and 300 mm or less. The concrete block for pavement is chamfered 4 mm or more and 20 mm or less in a depth direction, 2 mm or more and 20 mm or less in a direction of the upper end surface perpendicular to the side and the depth direction, and 2 mm or more and 30 mm or less in a corner part of the upper end surface.SELECTED DRAWING: Figure 3
【課題】個々のブロックの摩耗、欠け、割れが生じ難くなると共に、路面全体の段差、沈下、水平移動（ずれ）、わだち掘れが生じ難く、長期間に亘り良好な路面性状を維持でき、また、車両の走行騒音を抑制できる舗装用コンクリートブロックおよび舗装構造を提供する。【解決手段】セメントおよび前記セメント粒子の平均粒径の１／５０以上１／５以下の平均粒径のフィラーを含む粉体と、細骨材と、粗骨材と、水を含むセメント組成物からなり、前記水の前記セメントに対する質量比が０．２８以下であり、前記舗装用コンクリートブロックは、上端面の平面形状が１辺５０ｍｍ以上３８０ｍｍ以下の正六角形、厚さが５０ｍｍ以上３００ｍｍ以下である角柱状であり、前記舗装用コンクリートブロックは、深さ方向に４ｍｍ以上２０ｍｍ以下、辺および深さ方向に垂直な上端面方向に２ｍｍ以上２０ｍｍ以下、上端面の角部に２ｍｍ以上３０ｍｍ以下の面取りを施した。【選択図】図３
