随着新型沥青混合料的出现和现代交通对集料要求的提高,常规的马歇尔设计中经常出现密度和稳定度随沥青用量的增加没有明显峰值、空隙率偏小或过大、矿料间歇率偏低等异常现象。通过室内马歇尔试验,分析了这些异常现象产生的原因,并提出了适当的处理措施,以适应现阶段马歇尔试验设计的需要。
With the advent of new asphalt mixtures and the increasing demand for aggregate from modern traffic, the conventional density and stability of Marshall designs have no obvious peak with the increase of asphalt content, the void ratio is too small or too large, Low and other anomalies. Through the indoor Marshall test, the causes of these anomalies were analyzed, and the appropriate treatment measures were put forward to meet the needs of Marshall test design at the present stage.
