架路面换铺OGFC应用研究

为提高既有城市高架路面排水能力，以及雨天行车安全性与效率，通过配合比设计，并以实体工程项目为载体，研究将高架道路常规性沥青路面换铺成排水性能佳、行车噪声低、舒适性强的排水沥青路面。研究结果表明，采用OGFC-13所换铺高架路面的各项路面性能指标良好，达到了标准和设计要求。研究成果可为同类高架路面换铺施工提供参考与借鉴。

Study on Application of OGFC to Replace Viaduct Pavement

In order to improve the drainage capacity of the existing urban viaduct pavement, as well as the safety and the efficiency of elevated traffic in rainy days, through the mix ratio design and taking a real project as the carrier, the replacement of the conventional asphalt pavement of the elevated road with the excellent drainage performance, low driving noise and strong comfort of drainage asphalt pavement is studied. The results show that the pavement performance indexes of the viaduct pavement replaced by OGFC-13 are good, and meet the requirements of standard and design. The research results can provide the reference for the replacement construction of the similar viaduct pavements.
