摘要
OGFC-13型排水沥青铺面能够大幅提高雨天行车的舒适性和安全性,是实现海绵城市理念的功能性路面。现对OGFC-13沥青混合料的原材料、配合比设计、路用性能试验和施工环节关键要点进行研究,通过已建高架的验证和新建高架路的工后检测,证明了采用RST高黏度改性剂的排水沥青混合料,具有良好的高低温、抗水损性能,以及优异的抗飞散能力,能够抵抗路面早期破坏,提高耐久性和在高架中服役的寿命。对排水路面在高架快速路上的应用研究具备指导意义。
OGFC-13 porous asphalt pavement can significantly improve the comfort and safety of driving in rain,and is a functional pavement that can realize the concept of sponge city.This paper investigated the raw materials,mix design,road performance tests and key points of construction of OGFC-13 asphalt mixture.The verification of the built elevated road and post-work tests of the new elevated road showed that the porous asphalt mixture with RST high-viscosity modifier had good high and low temperature performance,water damage resistance,and excellent anti-flutter ability.The mixture could resist early damage of the pavement and improved the durability and service life of the elevated road,which had guiding significance for the application of porous pavement in elevated expressways.
