摘要
通过对不同离析程度混合料的级配及沥青含量的理论分析,试验研究表明,离析在一定范围内对混合料的性质没有太大影响,当离析超过一定限度时,混合料质量恶化;离析对路面空隙率有直接影响,当空隙率超过一定限度时,对路用性能影响很大。
Through theoretical analysis of graduation of different separation degree mixture and asphalt content, the experimental research indicated that separation had not big influence on the mixture properties at the certain scope, when separation exceeded certain limitation, the mixture quality will deteriorated. Separation had direct influence on road pavement porosity ration, when porosity ration exceeded some limitation, which had bid influence on road performance.
