Abstract

The invention relates to an elastic-plastic body material for filling bridge gaps. The elastic-plastic body material is characterized by comprising a cementing material and crushed stone in a mass ratio of 4:1 to 3:1, wherein the cementing material comprises the following components in percentage by weight: 70%-80% of petroleum asphalt, 3%-6% of SBS (Thermoplastic Styrene-butadiene Rubber), 5%-10% of anti-rut agent, 5%-10% of talcum powder and 5%-15% of petroleum resin. The cementing material and the crushed stone are mixed and stirred to be an elastic-plastic body under normal temperature and normal pressure. The materials are easy to acquire, the material structure is simple, the manufacturing cost is low, and the integrated performance is excellent.

Description

technical field [0001] The invention relates to an elastic-plastic body material for filling gaps in bridges. Background technique [0002] With the increasing development of transportation, roads, bridges, and vehicle traffic increase, and the driving speed increases, research, design, and construction units have higher and higher requirements for bridge expansion joints. As a bridge as a whole, the bridge expansion device has become a very important part of highway traffic, and its functions in terms of load-bearing, expansion, waterproof, and driving comfort will directly affect the overall effect of the bridge. [0003] At present, the elastic body expansion devices used in bridges are divided into zinc iron sheet expansion joints and TST crushed stone elastic expansion joints. The elastic body expansion device is a simple expansion joint device. The TST crushed stone elastic expansion joint device can be used when it is within the range. After the special elastic-plast...
