摘　　要：沥青混合料试验室现有搅拌装置存在诸多缺点,无法完成MA沥青混合料的试验研究。为满足MA沥青混合料试验的要求,采用正交试验的方法,以沥青混凝土拌合物宏观和微观均匀度作为测定指标,通过安排少量的多因素试验,确定了最优的搅拌装置结构参数及最优搅拌温度,并找到了影响搅拌质量的首要参数,制造出试验样机,填补了同类试验设备的空白,解决了MA沥青混合料无相关试验设备的难题。There are many disadvantages on laboratory stirring device for asphalt mixture,which have led to failure of MA asphalt mixture experimental study.In order to meet test requirements for MA asphalt mixture,by adopting the method of orthogonal test,by using macro and micro uniformity index of asphalt concrete mixture as the testing index targets,through a small amount of multi-fac-tors test,both optimal stirring device structure parameters and optimal mixing temperature have been determined,the primary param-eters influencing stirring quality have been found,so a test prototype device has been produced,which has filled up the blankness of similar test equipment,and resolved the problem of shortage of the relative test equipment for MA asphalt mixture.
