摘 要:介绍了一种加铺2cm混凝土超薄层修复旧混凝土路面的技术。分析了旧路面加铺超薄混凝土层的可行性，研究了加铺混凝土层的技术路线及材料配比，探讨了施工工艺对混凝土流动性和力学性能的影响。工程实践表明，采用自密实早强型聚丙烯纤维细石混凝土超薄罩面修补技术，养护7d后即可开放交通。经过一年多的使用观察发现，路面无开裂和明显的磨损现象，达到了设计的预期目的。 

Abstract: A kind of 2cm ultra-thin concrete overlay on old concrete pavement technology is introduced. The possibility of ultra-thin overlay is analyzed theoretically, and the technical routine and mixture ratio of ultra-thin overlay concrete are studied. The influence of the construction technology on concrete liquidity and mechanical properties are discussed. The road can be opened for traffic after curing 7d in the engineering project by using the early strength and self-compacting type polypropylene fiber fine stone concrete paving technology. After more than a year of use observation, there is no cracking and obvious wear phenomenon on the concrete pavement, therefore, the technology achieves the expected aim of design.
