沥青混合料生产配合比调整中的几个问题

一个好的目标配合比只是生产高质量沥青混合料的前提,好的设计能否在生产中落实还取决于生产配合比设计及验证。结合某高速公路车辙专项处治工程对生产配合比调整过程中的几个常见问题,如冷料仓上料速度、振动筛布设、马歇尔试验等进行论述。只有重视了这些环节才能增加试验数据的可信度,提高其数据对于生产过程的控制水平。

Several Issues on Adjustment of Asphalt Mixture Production Proportion

Asphalt mixture production with good quality not only depends on a good objective proportion design,but also decides on production proportion design and adjusting.Through a highway rutrepairing engineer project several issues of production proportion adjustment are discussed such as transporting material through cold material storehouse,vibrant sieve setting and Marshall test.A conclusion is maken that only these steps attached importance can the test data reliability be increased and can the control production run level be improved.
