High-viscosity modified asphalt-adopted white and black pavement structure

Abstract

The invention discloses a high-viscosity modified asphalt-adopted white and black pavement structure. The structure comprises an original cement concrete pavement, a high-viscosity modified emulsifiedasphalt adhesion layer and a modified asphalt thin overlay layer; the upper surface of the original cement concrete pavement undergoes disease treatment and milling / planing treatment; the high-viscosity modified emulsified asphalt adhesion layer is paved on the upper surface, undergoing the disease treatment and milling / planing treatment, of the original cement concrete asphalt; and the modifiedasphalt thin overlay layer is paved on the upper surface of the high-viscosity modified emulsified asphalt adhesion layer. Compared with the prior art, the structure has the beneficial effect of sufficiently utilizing the existing road edge stones and manhole covers without enhancing the elevations of the road edge stones and manhole covers, has the advantages of saving the raw materials, decreasing the working procedures, reducing the cost, improving the environment, improving the road quality, prolonging the road life and improving the driving comfort, and is capable of decreasing the bridgeload when using white and black asphalt concrete pavements on the bridge surfaces so as to prolong the service life of the bridge surface.

Description

【Technical field】 [0001] The invention relates to the technical field of white-and-black asphalt concrete pavement, in particular to a white-and-black pavement structure using high-viscosity modified asphalt. 【Background technique】 [0002] The traditional white-and-black asphalt concrete pavement structure is as follows: After the original cement concrete pavement surface is treated and milled and roughened, the emulsified asphalt bonding layer is spread, and the medium-grained asphalt concrete layer is laid on the surface of the emulsified asphalt bonding layer. Sprinkle the emulsified asphalt bonding layer on the surface of the medium-grained asphalt concrete layer, and then lay the fine-grained asphalt concrete surface layer on the surface of the emulsified asphalt bonding layer. Before the asphalt concrete pavement is laid, the elevation of curbstones and manhole covers will be raised, and most of them will be replaced. There are many construction procedures. It consu...
