PROBLEM TO BE SOLVED: To provide a pavement structure which can avoid an occurrence of flood disaster in a case of a local heavy rainfall such as guerrilla-type heavy rain while a roadbed is prevented from being damaged due to moisture and which can be constructed easily.SOLUTION: A pavement structure 100 comprises a water-shielding layer 20 laid on a roadbed 10, a base course 30 formed on the water-shielding layer 20, a pavement layer 40 formed on the base course 30, and a gutter 50 installed in the area adjacent to the base course 30 in a substantially horizontal direction, and a drain passage 51 which is drainage means for causing the moisture gathered on the water-shielding layer 20 to flow into the gutter 50 is installed. The water-shielding layer 20 is formed of a synthetic resin-made water-shielding sheet material, and the base course 30 is formed by installing and solidifying a mixture of crushed stone material, a cement-based solidified material, a nodulizing agent and water, on the water-shielding layer 20, and the pavement layer 40 is formed by installing and solidifying porous asphalt or porous concrete on the base course 30.SELECTED DRAWING: Figure 1 |
