Problems solved by technology

[0006] At present, poured asphalt concrete + SMA and double-layer epoxy asphalt concrete are the main pavement methods for bridge deck pavement. The cast asphalt concrete + SMA pavement system has excellent low temperature and fatigue performance, but the high temperature rutting resistance is not ideal; Epoxy asphalt concrete has excellent high temperature performance, but poor low temperature crack resistance

Abstract

The invention belongs to the technical field of compositions of high polymer materials, and particularly relates to a polymer alloy for steel bridge deck pavement. The polymer alloy comprises the following components: polyarylene sulfide, an acrylonitrile-butadiene-styrene copolymer, a grafting initiator and asphalt. The polymer alloy has the advantages of excellent high-temperature rutting resistance, excellent low-temperature cracking resistance, excellent tensile property and high bonding strength with a steel plate.

Description

technical field [0001] This application belongs to the divisional application of 201910311772.X. [0002] The invention belongs to the technical field of polymer material compositions, in particular to a polymer alloy used for steel bridge deck paving and a preparation method thereof. Background technique [0003] With the rapid growth of infrastructure investment in my country, bridge construction has entered a new era, and more and more, larger and longer bridges will be built, which provides a broad world for steel structure bridges ( "Application and Prospect of Steel Structure Bridges in China", Zhang Yi, Urban Construction Theory Research, No. 35, 2013, p. 35, published on January 16, 2014). Compared with the ordinary reinforced concrete structure, the steel structure has the advantages of uniformity, high strength, fast construction speed, good seismic performance and relatively high recovery rate. Considering these factors, if the weight of the steel structure is li...
