Zusammenfassung: | The utility model discloses a road structure capable of reducing reflection cracks, which belongs to the technical field of road structures and comprises a base layer, a PVC (polyvinyl chloride) pipe is inserted into the inner side of the base layer, a rubber strip is annularly arranged on the outer wall of the base layer, and a steel reinforcement framework is arranged on the inner side of the base layer. The steel bar framework is formed by welding transverse steel bars and longitudinal steel bars, a first surface layer is laid on the upper surface of the base layer, a geogrid is laid on the upper surface of the first surface layer, and a second surface layer is laid on the upper surface of the geogrid. The expansion tensile stress is reduced, the base layer is prevented from cracking, and meanwhile, the rubber strip is arranged on the outer wall of the single modular base layer, so that a certain gap is formed between every two adjacent modular base layers, the influence of thermal barrier cold contraction |
