Green renovation and upgrading construction method of cement concrete pavement

Abstract

The invention relates to an environment-friendly rebuilding and upgrading construction method for a cement concrete pavement. The environment-friendly rebuilding and upgrading construction method comprises the following steps of (1) investigation, analysis and detection, (2) treatment of subgrade subsidence disengagement, (3) treatment of broken plates, (4) treatment of strip belt deep cracks, (5) subgrade pavement reinforcement and acceptance and the like. The environment-friendly rebuilding and upgrading construction method has the advantages of being environmentally friendly, convenient to construct, low in cost and the like.

Description

technical field [0001] The invention relates to a construction method for reconstruction of cement concrete pavement, which is suitable for the construction of disease treatment of cement concrete pavement. Background technique [0002] With the continuous advancement of modernization, the practicality of automobiles has become more and more common, and the axle loads of automobiles have become increasingly heavy and due to reasons such as design and construction, the early design standards of the old cement concrete pavement were low, and a large number of old cement, Damage to the concrete pavement: local staggering, pockmarked surface, enlarged joint width, loud driving noise, etc., which seriously affect the use function of the road. Unlike the repair of asphalt pavement, the repair of cement and concrete pavement is relatively difficult. [0003] The traditional restoration of cement and concrete pavement generally has the following measures: 1. Add new cement concrete...

[0002] With the continuous advancement of modernization, the practicality of automobiles has become more and more common, and the axle loads of automobiles have become increasingly heavy and due to reasons such as design and construction, the early design standards of the old cement concrete pavement were low, and a large number of old cement, Damage to the concrete pavement: local staggering, pockmarked surface, enlarged joint width, loud driving noise, etc., which seriously affect the use function of the road

Unlike the repair of asphalt pavement, the repair of cement and concrete pavement is relatively difficult

[0003] The traditional restoration of cement and concrete pavement generally has the following measures: 1. Add new cement concrete surface directly on top of the original concrete pavement. The cracks in the pavement are also not dealt with, and the problem of cooperation between the old and new cement concrete pavement is not solved; 2. Directly add Paving the asphalt concrete surface layer, the process is simple and practical, the disadvantage is that there is no good friction between the old and new pavement structural layers, the pavement is easily damaged by various factors, and the pavement cracks are not treated, and the reflective cracks on the pavement cannot be effectively prevented ; 3. Destroying the original road surface and re-constructing, the construction period is long, the cost is high, the original cement concrete road surface is wasted, and the existing traffic transportation is greatly affected
