透水性沥青混合料路用性能的研究

Study on Performance of the Previous Bituminous Mixture

通过 ４ 种级配类型，介绍了路用透水性沥青混合料的组成成分及其特点，并在其最佳沥青量和空隙率的条件下，对透水性沥青混合料的路用性能，包括高温稳定性、低温抗裂性、疲劳特性及抗滑性能作了试验研究。试验结果显示：采用滴落试验确定透水性沥青混合料的最佳沥青用量是可行的；透水性沥青混合料具有相当强的抗滑性、透水性及抗车辙能力，能很好地满足沥青面层路用性能的要求。

This paper by means of forth grades, introduces the component parts and its characteristics of the pervious bituminous mixture, studies and analyzes the pavement performance of anti rutting, anti cracking and fattgue with the optimum oil content. The test results indicate that it is feasible to define the optimum oil content of the pervious bituminous mixture with the method of drop leaking test,the pervious bitiuminous mixture has strenger ability of the anti rutting and anti cracking and pervious, and it can meet the need of pavement performance of the bituminous surface course.
