Abstract

The utility model discloses a gravel road surface. The gravel road surface is characterized by comprising a macadam foundation, a concrete cushion layer, a mortar stickup layer and gravels. The thickness of the macadam foundation is 70 mm to 90 mm. The concrete cushion layer is arranged on the upper surface of the gravels. The thickness of the concrete cushion layer is 30 mm to 50 mm. The concrete intensity adopted by the concrete cushion layer is C20. The mortar stickup layer is arranged on the upper surface of the concrete cushion layer. The thickness of the mortar stickup layer is 15 mm to 25 mm. The gravels are laid on the upper surface of the mortar stickup layer. The gravels are arranged at intervals along the mortar stickup layer. The thickness of protrusion of the gravels from the mortar stickup layer is 10 mm to 12 mm. The gravel road surface is simple and useful.
