国省道沥青路面设计中存在的问题及改进策略分析

近些年我国国民经济飞速发展,交通运输行业也取得了很大的进步,耐久高效的运输条件在很大程度上推动我国综合实力的不断提升,而路面设计是道路工程建设过程中最为重要的一项内容,路面结构一旦受到破坏就会严重威胁到整个道路工程的使用安全性和寿命,特别是随着车辆载重和交通量的持续不断增长,想要不断延长路面和道路工程使用寿命就对路面设计工作提出了更大的挑战,要求在具体设计过程中要结合实际情况合理设计路面结构和混合料配比,并保证施工原材料质量符合工程建设实际要求。就我国目前情况来看,沥青路面是综合性能比较高的一种路面形式,本文就国省道沥青路面设计中存在的问题及改进策略进行简要分析。

Analysis on Problems and Improvement Strategies in Designing National Highway Asphalt Pavement

In recent years,China's national economy has developed rapidly,and the transportation industry has made great progress.Durable and efficient transportation conditions have promoted the continuous improvement of China's comprehensive strength.The pavement design is the most important content in the road engineering construction process.Once the pavement structure is damaged,it will seriously threaten the safety and life of the entire road project.Especially with the continuous increase of vehicle load and traffic volume,continuously extending the service life of pavement and road engineering poses greater challenges to pavement design.It is required to reasonably design the pavement structure and the mix ratio in the specific design process in accordance with the actual situation,and ensure that the quality of the construction raw materials meets the actual requirements of the project construction.As far as the current situation in China is concerned,asphalt pavement is a kind of pavement with relatively high comprehensive performance.This article briefly analyzes the problems and improvement strategies in the design of national and provincial highway asphalt pavement.
