排水沥青路面(PAC路面)因良好的排水、降噪和抗滑安全性能,运用前景广阔。在施工过程和质量控制中除了遵照一般的沥青路面要求和准则外,排水沥青路面施工还要高度重视沥青混合料改性剂的添加、拌和温度、摊铺碾压温度等关键环节的控制。文章通过对宁杭高速公路排水沥青路面施工技术要求的介绍和总结,可为排水沥青路面的推广起到积极作用。
Drainage of asphalt pavement (PAC pavement) due to good drainage, noise reduction and anti-slip safety performance, the use of promising. In the construction process and quality control in addition to follow the general asphalt pavement requirements and guidelines, the construction of drainage asphalt pavement should pay great attention to the asphalt mixture modifier addition, mixing temperature, paving temperature and other key aspects of the control. The article introduces and summarizes the technical requirements for drainage asphalt pavement of Ninghang Expressway, which can play an active role in the promotion of drainage asphalt pavement.
