Hot-mix asphalt mixture, construction compaction workability evaluation method and application of hot-mix asphalt mixture
The invention provides a hot-mix asphalt mixture, a construction compaction workability evaluation method and application thereof, the hot-mix asphalt mixture comprises asphalt, aggregate, mineral powder and fiber, and the passing rates (%) of each grade of sieve pores (mm) 16, 13.2, 9.5, 4.75, 2.36, 1.18, 0.6, 0.3, 0.15 and 0.075 in the grading composition are respectively 100%, 95%-100%, 62.5%-75%, 27%-34%, 19.5%-26%, 16%-19%, 14%-16%, 13%-15%, 10%-13% and 8%-12%. The fiber mixing amount of the hot mix asphalt mixture is 0.3%-0.4%, and the asphalt-aggregate ratio of the hot mix asphalt mixture is 6.0%-6.4%. The prepared hot-mix asphalt mixture has excellent construction compaction workability, when the hot-mix asphalt mixture is applied to airport pavement repair, the airport pavement repair work can be completed in consideration of efficiency and quality in the environment of short airport time and fast temperature drop at night, the effect is excellent, and the hot-mix asphalt mixture is worthy of popularization.
本发明提供了一种热拌沥青混合料、施工压实和易性的评价方法及其应用，其中热拌沥青混合料包括沥青、集料、矿粉以及纤维，其级配组成中各级筛孔(mm)16、13.2、9.5、4.75、2.36、1.18、0.6、0.3、0.15、0.075的通过率(％)分别为：100％、95％～100％、62.5％～75％、27％～34％、19.5％～26％、16％～19％、14％～16％、13％～15％、10％～13％、8％～12％。所述热拌沥青混合料的纤维掺量为0.3％～0.4％，所述热拌沥青混合料的油石比为6.0％～6.4％。本发明制得的热拌沥青混合料具备优良的施工压实和易性，应用于机场道面修复时，能够在夜间机场时长短、温降快的环境下兼顾效率与质量地完成机场路面修复工作，效果优良，值得推广。
