Abstract
The invention discloses a hardened road surface of a low-traffic-volume road of an ecologically vulnerable area. The hardened road surface of the ecologically low-traffic-volume road of the ecologically vulnerable area is characterized in that a lower-layer asphalt oil layer is sprayed onto a standard roadbed or road surface in sequence, and an oil core adsorption layer base cloth layer is paved on the lower-layer asphalt oil layer; an upper-layer asphalt oil layer is sprayed onto the paved base cloth layer; a complete oil core adsorption layer is formed by upward seepage of the lower-layer asphalt oil layer and downward seepage of the upper-layer asphalt oil layer; or before upper-layer asphalt oil is not cooled and condensed, one clean and dust-free bearing grain stone layer with uniform grain diameter and thickness can be scattered by adopting a synchronization method; and bearing grain stones are ground and embedded into the oil core adsorption layer to form the hardened road surface. With the adoption of the hardened road surface of the ecologically low-traffic-volume road of the ecologically vulnerable area, the hardened road surface of the ecologically low-traffic-volume road of the ecologically vulnerable area can be applied to roadbed hardening of three-high regions with high altitudes, high coldness, high temperature differences and the like, and desert regions including deserts, drought regions and the like, such as large-area desert regions including Tibet Plateau, Sinkiang and Inner Mongolia in China.
