Asphalt overlay treatment method of extreme-cold region cement concrete pavement
The invention discloses an asphalt overlay treatment method of an extreme-cold region cement concrete pavement, which includes the following steps: 1) inspecting damages which occur in the extreme-cold region cement concrete pavement, designing corresponding treatment schemes on the basis of the damages and performing corresponding treatment; 2) after the damages are treated, milling the original cement concrete pavement and trimming and cleaning old pavement; 3) spraying bonding asphalt layer, and leveling the bonding asphalt layer with asphalt sand in preset thickness; (4) paving a glass fiber grating and paving coarse granular asphalt concrete in preset thickness on the glass fiber grating; and (5) paving SBS modified asphalt in preset thickness on the coarse granular asphalt concrete. The method is carried out with common equipment, so that the method is low in maintaining and repairing cost, is convenient in repairing, can save time and labor intensity, is good in repairing effect and has good economic and social benefit.
