Zusammenfassung: | The asphalt concrete pavement with the good drainage performance comprises a roadbed, a drainage layer and a wear-resistant layer, a middle layer is laid on the upper end face of the roadbed, a drainage channel is fixed in the upper end face of the middle layer, meanwhile, a water through hole is formed in the top of the drainage channel, and the wear-resistant layer is arranged in the middle layer. The hydrophobic layer and the wear-resistant layer are laid on the upper end face of the middle layer, and the hydrophobic layer is located in the wear-resistant layer. According to the asphalt concrete pavement with the good drainage performance, the drainage channel, the connecting frame, the supporting frame, the hydrophobic layer and the wear-resisting layer are arranged, the hydrophobic layer has the hydrophobic characteristic, rainwater can intensively flow into the drainage channel to be drained after seeping through the wear-resisting layer, and the drainage performance of the asphalt concrete pavement is |
