摘要
路面材料复合介电常数模型是雷达检测路面结构体系含水量、孔隙率、压实度等指标的基础和关键。分析了相关文献的研究成果,剖析了复合介电常数模型的研究现状,讨论了各种模型的优缺点、局限性和适用范围等,论证了进一步研究路面材料复合介电常数模型的必要性。
Composite dielectric constant model of pavement material is the basis and key of detection of water content, void ratio, compactness and other indices of pavement structural system with radar. This paper analyzes the studying result of related literatures and the studying situation of composite dielectric constant model, discusses the advantages and disadvantages, limitations and application scopes of various models, and demonstrates the necessity of further study on the composite dielectric constant model of pavement material.
