The bad influence of internal and external factors will destroy the engineering quality of road and bridge, and reduce the service life. Reasonable application of reinforcement technology is helpful to improve the stability and security of road and bridge engineering and prolong service life. The reasonable application of reinforcement technique of the road and bridge engineering can promote the improvement of the bridge bearing capacity and stress, and it is benefit for promoting the overall capacity of bridge engineering. This paper mainly introduces several kinds of bridge reinforcement technology, and takes the application of reinforcement technology of pasting carbon fiber as the example to analyze the important effect of bridge reinforcement technology in the bridge engineering.%内外部诸多因素的不良影响都会造成路桥工程实际质量以及使用寿命大打折扣。合理应用加固技术有利于提升路桥工程稳定性以及安全性，延长使用寿命。路桥工程合理应用加固技术，可以促进路桥承载力以及应力的改善，有利于路桥工程提升整体通行能力。本文重点介绍几种路桥加固技术，并以其中粘贴碳纤维加固技术应用为例，分析路桥加固技术在路桥工程中的重要作用。
