本文就新路基的强度指标问题进行了讨论,认为新路基以弯沉作指标是完全可能的,而且应用起来更方便。文中给出了弯沉指标与其他指标(如模量)之间的关系,可供应用时参考。在新路设计中,土基强度是路面设计的一个重要参数。土基强度定得正确与否,对路面设计有很大的影响。目前,土基强度表 In this paper, the strength of the new roadbed indicators were discussed, that the new subgrade as a deflection indicators is entirely possible, and more convenient to use. The paper gives the relationship between deflection indicator and other indicators (such as modulus), which can be used for reference. In new road design, the strength of earth-based pavement design is an important parameter. Whether the strength of soil foundation is right or not has a great influence on pavement design. At present, the earth-based intensity table
