摘要
半刚性基层材料的抗冲刷性能是评价路面路用性能的一项重要指标,对整个路面特别是沥青路面的强度、使用质量和使用寿命都有十分重要的影响。针对半刚性基层材料常见的冲刷病害,在分析其形成机理的基础上,在室内利用冲刷试验仪研究抗冲刷性能的影响因素,提出了利用10 min内冲刷速率作为半刚性基层材料抗冲刷性能的评价指标。
In order to study the anti-brushing performance which is an important index affecting on the strenghth,performance and life of asphalt pavement are studied.The brushing mechanism of semi-rigid base course is analyzed.The effects of some factors on anti-brushing performance are analyzed by using a special device in the laboratory.With the result, the author put forward the main factor of anti-brushing performance which are influnenced by differing style material and differing gradation type.The rate of brushing in 10 minutes can be used to evaluate anti-brushing performance of semi-rigid base course.
