【摘要】：采用应力吸收层技术可以有效解决沥青面层与混凝土基层之间的层间黏结、裂缝的扩散与传递和路表水下渗等技术问题。把温拌橡胶沥青混合料用于应力吸收层,使得橡胶沥青的拌和与压实温度得到明显降低,达到节约能源,减少拌制气体排放,改善施工现场工作状况的目的,其高温稳定性和低温抗裂性能也得到明显提高。温拌橡胶沥青混合料作为应力吸收层对反射裂缝的抑制作用明显。本文分析了温拌橡胶沥青混合料的材料组成及其特性,研究了适合寒区的应力吸收层温拌橡胶沥青混合料的配合比设计过程,并对应力吸收层温拌橡胶沥青混合料的路用性能进行测试,找到适合寒冷地区温拌橡胶沥青混合料应力吸收层的组成材料,并进行路用性能及评价指标研究。
[Abstract]:The stress absorbing layer technology can effectively solve the pavement and the concrete base layer is bonded between the cracks, diffusion and transfer and road surface water infiltration technology. The warm mix asphalt rubber mixture for stress absorbing layer, the mixing and compaction temperature of asphalt rubber has been significantly reduced, saving energy mixing, reduce emissions, improve the working conditions of the construction site, the high temperature stability and low temperature crack resistance also improved significantly. The warm mix asphalt rubber mixture used as stress absorbing layer inhibits the reflection crack is obvious. This paper analyzes the material composition and characteristics of warm asphalt mixture, was studied suitable for cold stress with the layer of warm mix asphalt rubber mixture ratio design of absorption process, and the stress absorption layer of warm asphalt mixture road performance test, find suitable The material of the stress absorption layer of the warm mixed rubber bitumen mixture in cold area, and the study of road performance and evaluation index.
