| Abstract: | Rubber asphalt is becoming an important and effective material in pavement maintenance because of its better high temperature,fatigue-resistant and anti-cracking performance,but rubber asphalt is little used in project of Guangdong.Based on the maintenance project of Huihe expressway in Guangdong,the application of rubber asphalt is discussed in this paper in aspects of original material,mix proportion design,construction technology,and construction quality detection and so on.Stress absorbing layer with rubber asphalt of AR-SAMI and rubber asphalt covering of AR-AC13C is analyzed and concluded at last.The results and experiences can be used for similar projects in Guangdong. |
