采用大马歇尔法进行AC-25混合料设计探讨

Discussion on AC-25 Mixture Design by New Marshell Method

对于AC-25C型沥青混合料,目前主要采用的是小马歇尔设计方法。论述采用小马歇尔设计方法进行AC-25C混合料设计的不足,并通过室内试验,分析采用大马歇尔设计法进行AC-25C型混合料设计的可行性和必要性,提出采用大马歇尔设计法进行AC-25C混合料设计的相应技术要求。

Old Marshall design method is mainly adopted for AC-25C type asphalt mixture.This paper demonstrates the disadvantages in old Marshall design method,via lab experiments,it analyzes feasibility and necessity in adopting new Marshall method in AC-25C type mixture design,and gives relevant technical requests about adopting new Marshall methods in AC-25 mixture design.
