Zusammenfassung: | The invention discloses a road structure of an urban intersection, a bus station and a bus lane. The road structure comprises a surface layer, a middle surface layer, a lower surface layer, a base layer and a sub-base layer from top to bottom, a rubber asphalt stress absorption layer is arranged between the lower surface layer and the base layer, and the surface layer is composed of a semi-flexible material SFA13 sprayed with a stone exposing agent of 4-6 cm; the middle surface layer is formed by a semi-flexible material SFA16 doped with a phase change energy storage material of 6-8cm; the lower surface layer is made of an EME20 high-modulus asphalt mixture of which the thickness is 8-10cm; the base layer is composed of C-B-1 cement stabilized graded broken stones or gravels doped with bagasse fibers, waste rubber powder and water-absorbent resin sodium polyacrylate of 18-20cm, and the subbase layer is composed of 15-18cm fabricated regular hexagonal prism-shaped porous cement concrete.
