宁高高速公路路面改造方案设计研究

Research on the Design of Pavement Reconstruction in Ninggao Highway

依托宁高高速公路路面大修改造工程,考虑路面结构耐久性要求、原工程路面病害情况及施工过程中节能环保控制.制定出系统的路面大修改造措施及改造后路面结构方案,提出了以高模量沥青混合料和乳化沥青厂拌冷再生作为中下面层的新型路面结构形式。另外,研究表明通过对于乳化沥青厂拌冷再生的施工控制研究,能有效提高冷再生混合料的路用性能。

By considering the factors: pavement structure durability,energy conservation and environmental protection,and the pavement disease situation,the article make the systemic measurements of pavement renewal and reformation.It also put forward a new pavement structure,which take the EME and cold plant-mixed recycled asphalt mixtures with Emulsion Asphalt as middle and lower layer.The result of project shows that it can be effectively to improve the performance by the construction control of cold plant-mixed recycled asphalt mixtures with Emulsion Asphalt.
