| 摘 要： | 基层是沥青路面主要的承重层,其强度标准是路面结构层设计的关键。半刚性基层材料的无侧限抗压强度与CBR值往往是不成正比的,CBR值反映的是基层材料在有侧限情况下的承载比。目前,我国对基层材料配合比设计中只采用7 d无侧限抗压强度指标,在一些情况下不能反映路面基层实际的承载力,CBR值的应用将对正确选择原材料和水泥掺量的设计具有重要意义。 |
| 关 键 词： | CBR值 无侧限抗压强度 强度标准 配合比设计 |

| Abstract: | Road base course is the main supporting course of the semi-rigid base bitumen pavement,the strength design standard is the key factor to the pavement structure design.There is not so definite correlation between the CBR value and the unconfined compressive strength of the road base materials.Compared with the unconfined compressive strength,the CBR value reflects the bearing capacity of the road base material in the real situation.The unconfined compressive strength currently serve as the design factor of t... |
| Keywords: | CBR value unconfined compressive strength strength standard mixing proportion design |
