AR-OGFC沥青混合料在景区道路中的应用

Application of AR-OGFC Asphalt Mixture in Scenic Road Pavement

景区对环境静谧性和行车安全性的要求使得排水路面成为景区道路的必要选择。为充分发挥大空隙橡胶沥青混合料(AR-OGFC)良好的降噪、抗滑和耐久性能,针对橡胶沥青的制备方法及配合比设计方法进行了室内试验,并将其应用于广州市白江湖森林公园园区路面改善工程中。试验结果表明,以5.6%和5.7%的油石比设计出的排水橡胶沥青混合料具有良好的水稳定性和高温稳定性。试验路段检测结果表明,AR-OGFC沥青混合料具有良好的路用性能,能显著提升景区环境氛围。

The requirements of quiet environment and traffic safety in scenic areas makes the drainage pavement become a necessary choice. In order to give full play to the good performance of noise reduction,anti-skid and durability of AR-OGFC,the asphalt rubber and mixture were tested indoors and applied to the road pavement improvement project in Guangzhou Baijiang Lake Forest Park. The test results show that the drainage rubber asphalt mixture designed with a ratio of 5. 6% and 5. 7% of oil to stone has good water stability and high temperature stability. Test results of test section show that AR-OGFC asphalt mixture has good road performance,can significantly enhance the scenic environment atmosphere.
