Embodiment Construction

[0034] Below, the present invention will be further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of not conflicting, the various embodiments described below or the technical features can be combined arbitrarily to form new embodiments. .

[0035] like figure 1 As shown, a construction method based on cement pavement directly laying asphalt, including

[0036] Step 1. Lifting and milling of the old cement concrete pavement: when the old concrete pavement is 10CM-15CM lower than the completed road surface elevation, use a milling machine to mechanically roughen the road surface, and the old concrete pavement is lower than the completed road surface elevation by more than 15CM When pouring C30 concrete to upgrade the road surface, after the initial setting of the concrete road surface, use a milling machine to mechanically roughen the road surface. When the old concrete road surface is les...

Abstract

The invention provides a construction method for directly paving asphalt based on a cement pavement. The construction method comprises the following steps: 1, lifting and milling an old cement concrete pavement; 2, performing disease treatment on the old cement concrete pavement, the mud concrete pavement diseases comprise pavement cracks, plate settlement and hole pit repairing, and when multiple mud concrete pavement disease types exist in unit plates, performing treatment according to a patching method and a full-depth patch method; and 3, laying asphalt concrete on the repaired old cement concrete pavement. The problems that after asphalt is directly laid on an original cement concrete pavement, the asphalt concrete pavement arches, and a new asphalt concrete pavement cracks due to original concrete expansion joints are solved, and the laid asphalt pavement is longer in service life and higher in stability.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to a construction method for directly laying asphalt on a cement road surface. Background technique [0002] At present, the previously laid cement pavement can be seen everywhere in China. After a long period of use and maintenance, these cement pavements are generally complete, but the road surface has serious ups and downs, and traces of repair can be seen everywhere. At the same time, the road surface is uneven due to cracks, potholes and plates. Settlement, large-area cracks, cracks, and road settlement caused by poor quality control of road construction materials during concrete pavement construction. When asphalt concrete paving is required above this type of cement original road, it is mainly due to the existence of cracks on the original road surface. The cracks, potholes, and plate settlement and misplacement problems. The existence of such problems can easily le...
