BLOCK PRODUCT MADE OF CONCRETE
To provide a block product that can suppress expansion of the gaps over time between an asphalt pavement layer and the block product and enhance the weed-proof function.SOLUTION: A concrete block product 1 that comes into contact with an asphalt pavement layer is provided with a stepped surface 24 in contact with the lower surface of the asphalt pavement layer on a side 16 that functions as the abutting surface of the asphalt pavement layer. On the step surface 24 is formed a notch groove 26 having a first inclined surface 27 located on the outer side in the width direction of the block product 1 and a second inclined surface 28 located on the inner side in the width direction, the inclination angle α of the first inclined surface 27 with respect to the horizontal plane is set to be larger than the inclination angle β of the second inclined surface 28 with respect to the horizontal plane.SELECTED DRAWING: Figure 2
【課題】経年によるアスファルト舗装材層とブロック製品との隙間の拡大を抑制し得て、防草機能を高めることが可能なブロック製品を提供する。【解決手段】アスファルト舗装材層と接触するコンクリート製のブロック製品１は、アスファルト舗装材層の突き当て面として機能する側面１６に、アスファルト舗装材層の下面と接する段差面２４が設けられている。段差面２４には、ブロック製品１の幅方向外側に位置する第１傾斜面２７および幅方向内側に位置する第２傾斜面２８を備えたノッチ溝２６が形成されており、第１傾斜面２７の水平面に対する傾斜角度αが、第２傾斜面２８の水平面に対する傾斜角度βよりも大きく設定されている。【選択図】図２
