摘要
The present invention relates to an eco-friendly pavement construction method having excellent workability, stability, and economic feasibility and a pavement structure using the same. A special pavement material is obtained by using a raw material mixture (humus) including mineral. The earth and sand on the raw ground and cement are mixed and compacted by using the obtained special pavement material, and a stiffness base layer is formed. So, a designed cross-section of an existing base layer and an auxiliary base layer can be reduced without using aggregates. Also, the thickness of the base layer can be reduced, and the economic feasibility can be obtained. Moreover, the pavement construction method can prevent a defect which may be generated due to construction or a material by controlling hardening time after mixing the humus mixture and enabling even mixing in a batch plant. Also, the pavement construction method can obtain structural stability by performing integration by bonding a surface layer such as asphalt concrete and a humus mixture compact base layer and preventing a contraction crack. The pavement construction method also can remarkably reduce a use amount of the materials such as cement and the asphalt concrete and have eco-friendly strength.
