压碎值是评价集料抵抗压碎性能的指标。现行规范只对粒径(9.5~13.2 mm)集料的试验方法、步骤和评价指标有所说明,并未提及其它粒径和沥青混合料。结合我国道路实际情况,提出了 SMA 沥青混合料压碎值的方法、步骤和评价指标。通过对高温压碎值和常温压碎值比较,得出 SMA 沥青混合料和单粒径集料压碎值的相关分析,供读者参考。
壓碎值是評價集料牴抗壓碎性能的指標。現行規範隻對粒徑(9.5~13.2 mm)集料的試驗方法、步驟和評價指標有所說明,併未提及其它粒徑和瀝青混閤料。結閤我國道路實際情況,提齣瞭 SMA 瀝青混閤料壓碎值的方法、步驟和評價指標。通過對高溫壓碎值和常溫壓碎值比較,得齣 SMA 瀝青混閤料和單粒徑集料壓碎值的相關分析,供讀者參攷。

Crushing value is the evaluation index of crushing resistance for aggregate.Whereas the current specification generally applies to test methods for the aggregate whose diameter is between 9.5 mm and 13.2 mm,not to other diameter and asphalt mixture.According to the current situation of road in our country,test methods,steps and evaluation index of crushing value for SMA asphalt mixture are put forward.Compared with the crushing value of aggregate in high and normal temperature,correlation analysis on crushing value of SMA and single diameter aggregate is concluded for reference.
