乳化沥青冷再生面层混合料配合比设计

Design of Mixture Mixing Ratio for Emulsified Bitumen Cold Regenerated Surface

随着沥青路面冷再生技术在国内的逐步深入,该技术相关工程实践也越来越多。该文结合上海某高速公路整治工程的实际情况,介绍了用于高等级路面下面层的乳化沥青冷再生混合料配合比设计流程,并进行了设计流程优化,提出了适用于高速公路下面层的乳化沥青冷再生混合料配合比。

With the progressive deepening of bitumen pavement cold regeneration technology in China,the engineering cases related to this technology are more and more.Combined with the practical condition of an expressway harnessing project in Shanghai,the article introduces the design flow of the mixing ratio of emulsified bitumen cold regenerated mixture used for the lower surface of the high-grade pavement,optimizes the design flow,and puts forward the mixing ratio of emulsified bitumen cold regenerated mixture suitably used for the lower surface of the expressway.
