浅谈矿物纤维在SMA沥青混合料设计和施工中的特点

Elementary Discussion on Characteristics of Mineral Fiber in Design and Construction of SMA Asphalt Mixture

矿物纤维在国内沥青路面工程大规模应用较少,且没有大规模用于间断级配混合料的经验和工程实例。矿物纤维在提高胶结料弹性、强度及韧性以及混合料可再生等诸多方面有很多优势,应用前景广阔。该文在重庆绕城高速公路SMA路面工程中矿物纤维大规模的应用为例,对矿物纤维在SMA沥青混合料设计和施工中的特点进行了详细阐述和特点。其成果可为后续矿物纤维在沥青混合料中研究、应用和推广,提供参考。

The mineral fiber has not been widely used in the asphalt pavement projects of China,and there is no experience and engineering cases of mineral fiber widely used for the gap graded mixture.The mineral fiber has many advantages to improve the elasticity,intensity and tenacity of cementing material,and the renewability of mixture with the wide prospect of application.The article introduces the wide application of mineral fiber in Chongqing Raocheng Expressway SMA Pavement Project,and sets forth the characteristics of mineral fiber in the design and construction of SMA asphalt mixture.Its result can be referred for the study,application and popularization of the mineral fiber in the asphalt mixture in the future.
