Thermal spray polymer modified asphalt waterproof adhesive layer paving structure of cement concrete bridge surface and construction method

Abstract

The invention relates to a thermal spray polymer modified asphalt waterproof adhesive layer paving structure of a cement concrete bridge surface and a construction method. The structure is characterized in that a waterproof adhesive system is arranged on a concrete bridge panel, and an asphalt concrete bridge surface paving layer is also paved on the waterproof adhesive system, wherein the waterproof system consists of a waterproof adhesive layer, an asphalt water sealing band, an antiseptic asphalt layer and a prefabricated drainage groove. The paving layer for paving the asphalt concrete bridge surface consists of a lower paving layer of modified asphalt building mastic macadam SMA-16 and an upper paving layer of modified asphalt building mastic macadam SMA-13. The construction method comprises the following steps: treating the bridge panel, spraying the waterproof adhesive layer, spreading an antisticking crushed stone layer, grinding the waterproof adhesive layer, sticking the asphalt water sealing band, painting the antiseptic asphalt layer and mounting the prefabricated drainage groove. The paving structure disclosed by the invention has very high high-temperature deformation resistance, antifatigue, aging resistance, water damage resistance and low temperature cracking resistance capacity, and has favourable construction workability, so that the structure has a higher industry use value.

Description

technical field [0001] The invention relates to a pavement structure and a construction method in the field of cement concrete bridges, in particular to a pavement structure and a construction method of a thermal spray polymer modified asphalt waterproof bonding layer on a cement concrete bridge deck. Background technique [0002] Bridge deck pavement is a very important link in the bridge construction process. This is because the bridge deck pavement is directly provided to users, which directly affects the safety and comfort of driving. At the same time, the bridge deck pavement also plays an important role in protecting the bridge structure. play an important role. However, with the rapid development of my country's economy, there are a large number of heavy-duty and overloaded vehicles, and the bridge deck pavement is the most prone and earliest part of the bridge to be damaged during the use of the bridge. [0003] Asphalt concrete bridge deck pavement has been widely ...

AI Technical Summary

Problems solved by technology

[0015] The purpose of the present invention is to overcome the defects existing in the existing asphalt concrete bridge deck pavement, and provide a new cement concrete bridge deck thermal spray polymer modified asphalt waterproof bonding layer pavement structure and construction method, the technology to be solved The problem is that the pavement structure must have high high temperature deformation resistance, fatigue resistance, aging resistance, water damage resistance and low temperature cracking resistance, and has good construction workability, so it is more suitable for practical use, and has Industrial use value
