本文简要讨论了路面结构非破损评价的基本方法及其在路面管理中的重要性,并分析了应变指标在柔性路面设计中的作用及国际上一些现行设计方法对应变指标的考虑。由此提出了反算沥青路面面层底部拉应变的基本设想,并推导出应变计算的基本公式。文中还论述了误差产生的原因及补偿方法。
This paper briefly discusses the basic methods of non-destructive evaluation of pavement structures and their importance in pavement management. It also analyzes the role of strain indexes in flexible pavement design and some international design considerations for strain indices. Based on this, the basic assumption of calculating the tensile strain at the bottom of asphalt pavement is put forward, and the basic formula of strain calculation is deduced. The article also discusses the error causes and compensation methods.
