沥青混凝土路面的平整度控制

Control of Evenness of Bituminous Pavement

准确控制基准面(线),按规定操作摊铺机,合理安排碾压工序,做好纵横接头及桥涵两头的处理,严格控制混合料的油石比及矿粉含量,可以达到提高沥青混凝土路面平整度的目的。

To improve the evenness of bituminous pavement, we should do this way: controlling precisely the ref-erence plane (line) ,operating the spreader according to the rules, arranging properly the rolling procedure, han-dlling well the vertical and horizontal joints and both ends of bridges and culverts, controlling strictly the ratio of bituminous and stone and the contents of mineral powder of the mixture.
