【摘要】：课题主要通过室内试验和试验路铺筑，对用于解决沥青路面抗滑性能和水稳定性能的SAC13沥青混合料进行了深入研究。重点研究了SAC矿料级配设计与检验方法在级配设计与施工过程中的应用，SAC13沥青混合料的路用性能、压实特性及SAC13沥青混合料的施工等。课题首先结合用以解决高速公路沥青路面抗滑性能不足和水破坏严重现象的骨架密实结构沥青混合料的设计，研究了沥青混合料骨架密实结构的形成标准，建议了判定沥青混合料结构类型的指标，研究了SAC13沥青混合料的强度构成。课题在简单评述SAC开发与应用的基础上，详细介绍了SAC矿料级配设计与检验方法，并通过SAC13级配设计的具体应用，提出了应用VCAAC检验方法的技巧和保证沥青混凝土性能稳定的不同筛孔通过量的误差范围。课题通过试验路的施工，首先证实了SAC矿料级配设计与检验方法简单、灵活，适用性强；在正确的碾压方法下，，SAC13沥青混合料的压实性能良好。其次，通过分析施工中存在的问题，提出了提高施工质量的主要方法。另外，试验段的跟踪观测数据证实了SAC13沥青混合料良好的使用性能。
[Abstract]:The subject is mainly built by indoor test and test road. In this paper, the SAC13 asphalt mixture used to solve the skid resistance and water stability of asphalt pavement is studied. The design and test method of SAC gradation in the process of gradation design and construction is emphatically studied. Yes. SAC13 asphalt mixture road performance, compaction characteristics and SAC13 asphalt mixture construction. Firstly, combining with the design of the framework dense structure asphalt mixture, which is used to solve the problem of insufficient skid resistance and serious water damage of expressway asphalt pavement, the formation standard of the framework dense structure of asphalt mixture is studied. The index of judging the structure type of asphalt mixture is suggested, and the strength composition of SAC13 asphalt mixture is studied. On the basis of a brief review of the development and application of SAC, this paper introduces in detail the design and testing methods of SAC ore gradation, and through the specific application of SAC13 gradation design. The technique of applying VCAAC test method and the error range of different sieve hole throughput to ensure the stability of asphalt concrete performance are put forward. Through the construction of the test road, it is proved that the design and inspection method of SAC ore gradation is simple, flexible and applicable. The compaction performance of SAC13 asphalt mixture is good under the correct rolling method. Secondly, by analyzing the problems existing in the construction, the main methods to improve the construction quality are put forward. In addition, the tracking data of the test section confirmed the good performance of SAC13 asphalt mixture.
