| 摘 要： | 在不同条件下对广西地区常见各类岩石轧制碎石测试其强度变化，认为仅用碎石的压碎值或芯样抗压强度不能反映其合格性，提出增加碎石的软化系数，CBR值指标评价其路用合格性。

| Abstract: | This paper discusses the measurement and variation of strength of typical crushed rocks under different conditions in Guangxi. It was found that crush value and compression strength of cored sample in the current specifications were not sufficient for quality material. Additional procedures, measuring softening coefficient and CBR value, were developed for the evaluation of crushed rocks for highway base course. |

| Keywords: | crushed rock crush value softening coefficient CBR value |
