Zusammenfassung: | The utility model relates to the technical field of road construction, in particular to an asphalt pavement structure laid on an urban road, which comprises a base layer, a gravel layer, a cement layer, a first asphalt layer, a water-resisting layer and a second asphalt layer are sequentially laid on the top surface of the base layer from bottom to top, and the laying thickness of the first asphalt layer is the same as that of the second asphalt layer. Nylon separation nets are laid between the gravel layer and the base layer and between the gravel layer and the cement layer. The waterproof layer can prevent the pavement from being damaged due to rainy days and rainwater infiltration, the gravel layer can enable the pavement to be more stable, the cement layer can enable the pavement to be smoother when asphalt is laid, and the condition that the pavement is hollow is avoided.
