为了确定改性沥青应力吸收层混合料合理的旋转压实次数,采用自主研制的应力吸收层特种改性沥青结合料,进行旋转压实试验,分析旋转压实次数、油石比对混合料密实度的影响,结果表明:旋转压实次数和油石比对混合料密实度均有显著性影响,但油石比是混合料密实度的最显著性影响因素;旋转压实次数在35~55之间时密实度存在一个“递变”区域,结合应力吸收层材料特性及性能要求,确定旋转压实次数为50次。
In order to determine the reasonable rotational compaction times of the modified asphalt stress-absorbing layer mixture, the self-developed stress-absorbing layer special modified asphalt binder was used to conduct the rotary compaction test. The rotational compaction times, The results show that the number of rotary compaction and the ratio of stone to oil have a significant effect on the compaction of the mixture, but the ratio of stone to oil is the most significant factor affecting the compaction of the mixture. When the number of rotary compaction is between 35 and 55 Density There is a “transition ” area, combined with the stress absorbing layer material properties and performance requirements, to determine the number of rotary compaction 50 times.
