Application of Stress Absorbing Layer in Project

Abstract:

To study the anti-cracking mechanism of stress absorbing layer. This paper, which determines the parameter of the sand asphalt mix design of AC-5 and proceeds the mix design, is based on Xinyang freeway (The bid section 1 of Huazhuang-Xincai section). Asphalt content is tested by ignition oven asphalt content test.Screening aggregate recovered from ignition oven asphalt content test .Using roughness, thickness, compaction in field evaluation.The results show that the positive S model of aggregate gradation and reasonable construction temperature and construction technology are contributed to anti-cracking of stress absorbing layer.The impermeable SBS modified asphalt stress absorbing layer could prevent the base and subgrade from eroding.
