沥青玛碲脂碎石混合料强度形成与设计要点相关性分析

从沥青玛碲脂碎石混合料强度形成、关键的体积指标、工程算例三方面分析论证了沥青玛碲脂碎石混合料的强度形成机理和设计要点的相关性，指出提高SMA混合料高温稳定性在设计过程中应采取的措施。最重要一点SMA与其他混合料设计的主要区别是沥青？昆合料压实后粗集料的骨架空隙率必须小于或等于捣实状态下粗集料的骨架间隙率。

Correlation analysis on the correlation between strength growth of SMA mixture and the main points of its design

This paper discusses the correlation between the mechanism of strength - forming of SMA mixture and the main points of its design, which is based on the analysis on strength growth, the Key word index of volume, and calculation of engineering cases, and then put forwards to some measures to be taken in the process of design for improving the stability of SMA mixture at high temperature. It is important that the distinguishing in mix design for SMA and other mixtures is that the voids ratio of compacted coarse aggregates must be equal to or less than that of compacting coarse aggregates.
