摘要
针对采用普通SMA级配设计橡胶粉改性沥青混合料不能满足对SMA沥青混凝土空隙率要求的问题,通过大量室内试验,比较了采用普通SMA级配和间断级配的橡胶粉改性沥青混凝土的物理性能,提出了橡胶粉改性沥青混合料的设计方法。
The RMAC designed with nomal SMA gradation can＇ t satisfy the requirement of air void for SMA by specfications. In this paper, the auther compares the physical performance difference between CRMAC designed with normal gradation and gap gradation from a lot of lab experiment, putting forward the design method of RMAC.
