Problems solved by technology

[0005] 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 asphalt material compositions, and in particular relates to a polymer alloy used for steel bridge deck pavement. The polymer alloy includes the following components: polyarylene sulfide, acrylonitrile-butadiene-styrene copolymer, grafting initiator and asphalt. The polymer alloy has excellent high-temperature anti-rutting performance, excellent low-temperature cracking resistance, excellent tensile performance, and high bonding strength with a steel plate.

Description

technical field [0001] The invention belongs to the technical field of asphalt material compositions, and in particular relates to a polymer alloy for steel bridge deck pavement and a preparation method thereof. Background technique [0002] With the rapid growth of my country's infrastructure investment, bridge construction has entered a new era, and more and more, larger and longer bridges will be built, which provides a broad space for steel structure bridges ( "Application and Prospect of Steel Structure Bridges in China", Zhang Yi, Theoretical Research on Urban Construction, Issue 35, 2013, Page 35, published on January 16, 2014). Compared with ordinary reinforced concrete structures, steel structures have the advantages of homogeneity, high strength, fast construction speed, good seismic performance and relatively high recovery rate, and steel structures are stronger than ordinary stone bricks, and have super good Considering these factors, if the steel structure is li...
