摘要
透水性沥青混凝土具有其独特的环保、抗滑、安全、耐久等特点。这种沥青混合料是具有20%左右的空隙率、设计沥青用量为4.5%左右的间断级配沥青混凝土。由于它有透水性,路面水分可迅速排泄,能预防路面湿滑,从而减少交通事故。结合厦门市疏港路高架桥透水性沥青路面实际施工实例,研究探讨了透水性沥青路面的施工技术,具有一定的指导价值。
The permeable asphalt concrete has its distinctive characteristics of environmental protection, slip resistance, safety and durability. This kind of asphalt mixture is the gap graded asphalt concrete with about 20% void ratio and about 4.5% design asphalt dosage. The pavement water content can be rapidly discharged able to prevent the pavement from the moisture and slip because of its permeability so as to decrease the traffic accidents. According to the practical construction of the permeable asphalt pavement of Shugang Elevated Bridge in Xiamen, the article studies and discusses the construction technology of permeable asphalt pavement, which can be referred for the similar projects.
