Concrete pavement lifting structure and method

Abstract

In order to solve the problems of driving comfort and potential safety hazards caused by damage of a concrete pavement in the prior art, the embodiment of the invention provides a concrete pavement lifting structure and method. The concrete pavement lifting structure comprises a high-viscosity asphalt sealing layer, a high-viscosity asphalt mortar layer, a warm mixing modified SMA-10 layer and a bonding layer. The method comprises the following steps: if the concrete pavement has crack diseases, performing treatment; if no crack disease exists, performing shot blasting and bone exposing treatment on the concrete pavement; paving a high-viscosity asphalt sealing layer on the concrete pavement subjected to shot blasting and bone exposing treatment on the concrete pavement; and sequentially and additionally laying a high-viscosity asphalt mortar layer and a warm-mixing modified SMA-10 layer on a high-viscosity asphalt sealing layer, laying a bonding layer between the laid high-viscosity asphalt mortar layer and the laid warm-mixing modified SMA-10 layer, re-marking marking lines after compaction, milling and planing an asphalt concrete surface layer at the lap joint, and re-laying 1-2 layers of warm-mixing modified SMA-13. According to the embodiment of the invention, the concrete pavement is changed into the asphalt pavement, so that the structural quality of the concrete pavement is improved.

Description

technical field [0001] The invention relates to a concrete pavement lifting structure and method. Background technique [0002] The concrete pavement of the tunnel has been worn for many years, resulting in low friction, and vehicles are prone to slipping and causing traffic accidents. The concrete pavement of the tunnel has been damaged due to the increase of traffic volume along the line, the collision of vehicles and years of wear and tear, and the concrete spalled in some sections of the road and pits appeared. Concrete pavement has poor flatness, strong bumpy feeling, poor driving comfort and high driving noise, which is a great hazard to driving safety. Contents of the invention [0003] In order to solve the problems of driving comfort and safety hazards caused by the destruction of the concrete pavement existing in the prior art, the embodiments of the present invention provide a concrete pavement lifting structure and method. [0004] Embodiments of the present ...
