MS-2型微表处在路面抗滑性能处治中的适用性研究

摘要

For further research on the relationship between texture depth and asphalt content of Micro-surfacing pavement,the paper selected 6 representative insufficient anti-sliding performance index sec-tions,measured the texture depth and anti-sliding performance before and after the treatment,re-searched the applicability of the Micro-surfacing mixture to anti-sliding performance treatment.The results show that texture depth have a good correlation with aggregate gradation and asphalt content;texture depth and anti-sliding performance index had no obvious relationship;Micro-surfacing mixture can only improve the anti-sliding performance of pavement temporary,but cannot have a long-term effect.%为深入研究微表处路面构造与级配及沥青含量的关系，选取抗滑性能指数不足的代表性路段6处，在路面采取微表处处治前后，现场分别实测路面构造深度和抗滑性能指数，研究微表处在路面抗滑性能不足处治中的适用性。得出构造深度与集料级配和沥青含量有很好的相关性；构造深度与抗滑性能指数没有明显的关系；微表处只能暂时提高路面的抗滑性能，不能起到长效作用。
