Abstract

The invention discloses a functional steel bridge deck pavement system with snow melting and deicing functions. The pavement system comprises an anti-rust layer, a waterproof layer, a first coupling layer, an elastic concrete layer, a second coupling layer and a snow melting and deicing functional layer which are sequentially arranged from bottom to top and laid on a steel bridge deck. The anti-rust layer is 0.1-0.2 mm thick and made of zinc-rich epoxy resin. The waterproof layer is 2-4 mm thick and made of epoxy resin waterproof paint. The coupling layers are both 30-50 microns thick and made of silane coupling agent. The elastic concrete layer is 40-50 mm thick and made of epoxy resin rubber concrete. The snow melting and deicing functional layer is 10-20 mm thick and is an epoxy rubber functional layer doped with magnetite powder. The improved pavement system can prevent use of snow melting agents, pipelines or cables do not need to be paved, the three modes including strain ice breaking, strain heat release and microwave radiation heating are used together to achieve efficient snow melting and deicing, construction is convenient, the cost is low, maintenance and repair are easy, and energy conservation and environmental protection are achieved.

Description

technical field [0001] The invention relates to the technical field of bridge pavement, in particular to a functional steel bridge deck pavement system for melting snow and ice. Background technique [0002] In recent years, my country has intensified its efforts to build long-span steel bridges across rivers and seas. At present, my country's steel production capacity and steel prices have fallen, which is a good opportunity to promote the construction of steel structure bridges and improve the quality of highway bridge construction. The construction of steel structure bridges has become an industry consensus. Bridge deck pavement is an important part that affects the quality of steel bridge engineering, and directly affects the traffic capacity of the bridge and the safety of driving. [0003] At present, four kinds of pavement materials are basically used in the paving of steel bridges in the world: pouring asphalt concrete, roller compacted asphalt mastic concrete, modif...
