摘要
根据由不同马歇尔击实次数成型得到的密实度比随击实次数变化所形成的密实曲线,与旋转压实一次成型得到的密实曲线作比较,以此分析温拌沥青混合料和热拌沥青混合料的压实特性。由马歇尔击实和旋转压实密实曲线、密实度斜率和密实度能量指数的分析结果表明:温拌沥青混合料用旋转压实法成型时能够体现出比热拌沥青混合料更好的可压实性,而马歇尔击实成型时则得到与之相反的结果。
According to the compaction curve forms from the density ratio change with the compaction times change by the different number of Marshall compaction,compared with gyratory compacting densification curve,so that analyze the compaction characteristics of warm mix asphalt and hot mix asphalt. The analysis results of Marshall and gyratory compacting densification curve,the slope of densification curve and the densification energy index show that： using the gyratory compaction molding the warm mix asphalt can reflect better compactibility than the hot mix asphalt,and Marshall compaction molding got the opposite result.
