摘要
半刚性基层材料以其强度高、原材料来源广、修建成本低等优势成为我国公路建设中的主导路面基层类型。但现行的半刚性基层材料组成设计指标、材料结构单一,致使所设计的基层抗裂、抗冲刷能力不足,降低了其应用效果。为此,长安大学开展"公路半刚性基层材料结构理论、多指标控制设计方法及工程应用"研究,发现半刚性基层材料性能改善的有效途径在于改进材料的组成设计。本篇对该项目成果进行介绍,以进一步推广使用。
The notes from the editor The semi-rigid material is known for its high durability, abundant supply, and low cost, and it is the main material for road building in our country.However,the current designing guideline and raw materials used are somewhat lacking diversity.Ineffectiveness in cracking-resistance and flood resistance lower the overall performance.To solve this, Changan University conducts project ＂Constructional application of Semi-rigid material and multi-level designing system＂, and discovers that the most crucial step of refining the material is to reform the mixture.The following chapter is designated to honor the key establishments.
