摘要:
In recent years, Chinese social and economic development is rapid, people's living standards are gradually improved, a large number of motor vehicles are increasing, and road traffic problems are gradually prominent, so the government has increased the attention to road engineering construction. The construction of municipal roads and bridges has become the catalyst of urban development, which directly affects the rapid development of the city. The construction technology of road and bridge expansion joint is the key process of bridge deck pavement control. Construction quality will not only affect the image of the whole project, but also affect the service life of highway bridges and highway driving safety. This paper discusses the effect and significance of expansion joint on the construction quality of road and bridge engineering, analyzes how to improve the construction quality of expansion joint combined with the construction classification of devices, puts forward the construction quality control strategy of expansion joint, and optimizes its construction quality.
