发明名称 The improved pavement
摘要 An improved pavement is provided to construct the pavement easily by mixing concrete in the field, to drain rainwater actively by forming a permeable concrete layer and a surface protective coating layer, and to extend the life span of the pavement by increasing the durability. A pavement includes a rubble layer(21) spread on a ground layer(10), a permeable concrete layer(30) arranged on the rubble layer, a surface protective coating layer(40) spread on the permeable concrete layer, a primer layer(23) arranged on the surface protective coating layer, and an elastic surface layer(24) spread on the primer layer. The permeable concrete layer includes cement of 100 wt%, soil of 400 wt% and water of 100 wt%. The assembling force is improved by enlarging the contact area of cement with soil of 2 to 3 mm in grain size for the permeable concrete layer. A non-yellowing polyurethane-based binder or urethane coating agent is used for the surface protective coating layer.
