Abstract

The invention belongs to the field of road and bridge engineering, and particularly relates to a drainage pavement composite structure suitable for heavy traffic, the drainage pavement composite structure comprises an upper surface layer, a sealing layer, a middle surface layer, an anti-cracking bonding layer, a lower surface layer, a bonding layer and a base layer from top to bottom, the upper surface layer is a high-viscosity composite modified OGFC-13 open-graded asphalt mixture layer, and the thickness of the upper surface layer is 30-50 mm; the middle surface layer is a semi-flexible bearing layer with the nominal maximum particle size of 13.2 mm, and the thickness of the middle surface layer is 30-50 mm; and the lower surface layer is a high-viscosity composite modified discontinuous semi-open graded asphalt mixture layer with the nominal maximum particle size of 19mm or 26.5 mm, and the thickness of the lower surface layer is 50mm-80mm. The drainage pavement composite structure meets the use requirements of heavy traffic on the basis of having the advantages of the drainage pavement.

Description

technical field [0001] The invention belongs to the field of road and bridge engineering, and in particular relates to a drainage pavement composite structure suitable for heavy-duty traffic. Background technique [0002] Drainage pavement is a typical skeletal pore structure. A large number of connected spaces form a developed drainage network channel inside the road. Rainwater is discharged from the interior of the road body along the cross slope of the road through the network channel. , Anti-glare, good skid resistance, outstanding safety performance; noise reduction, mitigation of heat island effect, material saving, low-carbon environmental protection and other advantages. With the rapid promotion of the "sponge city" concept across the country, drainage pavement is gradually being designed and used as the surface layer of highway asphalt pavement. [0003] At the same time, with the rapid development of my country's transportation, the proportion of large-scale cargo...
