摘　　要：简要阐述了CGFC新型路面结构、性能原理和发展概况,通过现有信息资料总结与分析,结合工程实例,简要介绍了OGFC路面施工技术要点。采用高粘度沥青保证OGFC路面应有的大空隙率,提高其排水降噪能力和抗滑性能,同时也提高了抗变形的能力,解决了OGFC路面大空隙率与功能耐久性的矛盾,并延长路面使用寿命。Briefly elaborated the new OGFC road surface structure, the performance principle and the development status. The existing information summary and analysis, combined with the project instance briefly introduced the main technical points of the OGFC road surface construction. The Usage of high viscosity asphalt guaranteed the great percentage of voids which the OGFC road surface should have, thus enhanced its water draining, noise reducing abilities and the anti - slippery performance, simultaneously improved the anti - distortion ability. It solved the contradiction between the great voids percentage and the function durability of the OGFC road surface, and lengthened the road＇s service life.
