灌注式半柔性路面应用效果研究

Research on Application Effect of Pouring Semi-Flexible Pavement

课题组通过对灌注式半柔性路面灌浆材料的实验研究,开发出适合山东气候的专用灌浆料,自主研发的制浆设备能够连续生产极大提高了施工效率,对路面结构进行了优化,更适合半柔性路面结构受力情况。课题组通过材料、设备与路面结构一体化设计研究成果,依托邹魏路改扩建工程重载交通平交路口进行了试验路应用,通过1年多的使用情况观测半柔性路面结构抗车辙性能显著,路面抗滑与渗水等全部路用性能指标满足设计要求,服役效果非常理想,不仅节约了沥青等不可再生资源用量而且减少全寿命周期的养护费用,有效降低了重复建设对环境的破坏作用,半柔性路面是一种较理想的环保耐久型路面结构。

The research team developed a special grouting material suitable for Shandong’s climate through experimental research on perfusion semi-flexible pavement grouting materials. The self-developed grouting equipment can produce continuous production, which greatly improves the construction efficiency, optimizes the pavement structure, and is more suitable for the stress of semi-flexible pavement structure. Based on the research results of the integrated design of materials, equipment and pavement structure, the research team carried out test road applications at the heavy-duty traffic level crossing of the Zouwei Road Reconstruction and Extension Project. All road performance indicators such as skid resistance and water seepage meet the design requirements, and the service effect is very satisfactory. It not only saves the amount of non-renewable resources such as asphalt, but also reduces the maintenance cost of the whole life cycle, effectively reducing the destructive ef-fect of repeated construction on the environment, and is semi-flexible. The pavement is an ideal en-vironment-friendly and durable pavement structure.
