| 摘 要： | 通过对两种风化石粒料进行的CBR试验研究，分析了粒料的级配密实度、粒径小于0．075mm含量、粒径大于4.75mm的粗集粒含量和最大粒径与CBR值的关系，结果表明风化碎石粒料的CBR值与它的级配、密实度、小于0．075mm集料含量、大于4．75mm的集料含量和最大粒径有很大的相关性。

| Abstract: | Based on the trial study on two materials taken from weathered rock, the density of material gradation, and the content of grain size less than 0. 0075 mm, the content of grain size more than 4. 75 mm, and the relationship between the maximum size and CBR values are discussed in this article. The test results have shown that the CBR value of these weathered materials has a close correlation with the gradation of aggregates, the content of grain size less than 0. 0075 mm, the content of grain size more than 4.75 mm, and the maximum size. |
