摘要
本文简要介绍了国内外高等级公路上曾采用过的半刚性路面结构;论述了半刚性路面的技术经济效益;讨论了半刚性材料的回弹模量;论证了半刚性层底面的弯拉应力的验算应采用抗压回弹模量而不应采用弯拉回弹模量;最后介绍了几种半刚性材料的抗拉强度.
This paper presents briefly the semi-rigid pavement construction on high-class roads used domestially or abroad and discusses the technical economic benefits derived from the semi-rigid pavement construction.Based on the resilient modulus tests of semi-rigid materials in laboratory and field, it is concluded that the tensile stresse in bending at the base of semi-rigid layer should be calculated by the resilient modulus in compression rather than by flexural resilient modulus in tension. Finally, the tensile strength of several semi-rigid materials are given.
