Abstract

The invention provides a surface layer structure of a bus lane and a paving method, and relates to the technical field of road surface pavement. Diseases such as wheel rut, pushing upheaval, cracks and pit slots of general asphalt concrete pavement can be solved. The surface layer structure of the bus lane comprises a general road segment and a platform road segment, and a layer surface structureof the general road segment and the platform road segment sequentially comprises a cement concrete layer, a bonding layer and an asphalt concrete thin layer from bottom to top; the bonding layer of the general road segment is an asphalt bonding layer, and the bonding layer of the platform road segment is a polyurethane bonding layer or an epoxy resin bonding layer; the thickness of the cement concrete layer is not less than 20cm; the thicknesses of the polyurethane bonding layer and the epoxy resin bonding layer are not less than 3mm; and the thickness of the asphalt concrete thin layer is 1.5cm-2.5cm. The technical scheme of the surface layer structure of the bus lane and the paving method is suitable for the process of bus lane road pavement.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of pavement paving, in particular to a surface layer structure and a paving method of a bus lane. [0003] 【Background technique】 [0004] More and more attention has been paid to public transport, the urban public transport system has become more and more developed, and there are more and more bus lanes, such as bus lanes and BRT. Due to the heavy weight of the bus, the channelization is serious, and the road surface disease is also very serious. Such as ruts, pushing, crowding, cracks, potholes, etc. abound. [0005] Bus channelized traffic has strict requirements on the anti-rutting performance of the road surface. Damage from water damage such as potholes, peeling asphalt, etc. is also common. Ordinary asphalt concrete pavement cannot meet the corresponding requirements. [0006] At the entrance and exit of the bus platform, the vehicles frequently brake and start. The friction resistance of ...
