| 摘 要： | 该文利用冲刷试验仪进行了二灰碎石、水稳碎石等半刚性基层材料的室内抗冲刷试验,并在此基础上确定了半刚性基层材料的预冲刷时间,提出了在扣除预冲刷时间对试验结果的影响后,可利用7 min内的单位时间冲刷率,作为评价半刚性基层材料抗冲刷性能的指标。

| Abstract: | The brushing tester is utilized to carry out the indoor anti-bushing experiment of the semi -rigid base material such as lime ash-flying and cement stabilized crushed stones.On this basis, the article determines the time of pre-brushing of the semi-rigid base material,and puts forward that the unit time brushing rate in 7 minutes can be used as the index to evaluate the anti-brushing performance of the semi-rigid base material excluding the influence of pre-brushing time on the experimental result. |
