随着经济的不断发展,高速公路的作用越来越大,所承载的车流大越来越大,为了适应高速公路未来的发展,必须在特定时候对高速公路进行路面拓宽施工。当前利用的主要路面拓宽技术为路面拼接技术,这类技术可以有效降低工程施工量,减少施工费用,还能保证施工质量,最大程度的提高高速公路建设的经济效益。本文主要通过实际案例具体分析路面拓宽技术的应用。 Along with the continuous development of economy, the function of expressway is more and more large and the traffic flow carried by it is bigger and bigger. In order to adapt to the future development of expressway, it is necessary to widen the construction of expressway at a specific time. Currently, the main pavement widening technology is the pavement splicing technology. Such technologies can effectively reduce the construction volume, reduce the construction cost, ensure the construction quality and maximize the economic benefits of the expressway construction. This article mainly analyzes the application of pavement widening technology mainly through actual cases.
