Problems solved by technology

[0008] 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 its low-temperature cracking resistance is poor

Abstract

The invention belongs to the technical field of compositions of asphalt materials and particularly relates to aryl ether polymer alloy. The polymer alloy comprises the following components: polyarylene sulfide, polystyrene and a hydrogenated styrene-butadiene-styrene block copolymer containing filling oil. The polymer alloy is excellent in high-temperature rutting resistance, excellent low-temperature cracking resistance, excellent in tensile property and high in bonding strength with a steel plate.

Description

technical field [0001] The invention belongs to the technical field of aryl ether compositions, and in particular relates to an aryl ether polymer alloy and a preparation method thereof. Background technique [0002] Bridges are an important part of my country's transportation and the infrastructure of my country's national economic construction, which plays a huge role in promoting the development of the national economy. With the rapid development of my country's national economy, bridge construction has also achieved unprecedented development, and highway bridges are also constantly developing in the direction of large bearing capacity, high technology, large span, and high quality ("Talking about the status quo and development trend of bridge construction technology" , Gao Feng et al., Big Science and Technology, No. 6, 2014, pages 187-188, published on May 26, 2014). [0003] Since the completion of the Nanpu Bridge in the late 1980s, the construction of long-span bridg...
