浅析集料材质特性和加工特征对沥青混凝土的影响因素

Analysis of influence factors of aggregate material and processing characteristics on asphalt concrete

集料的质量主要取决于加工石料的岩石,应用于沥青路面的常用集料有石灰岩、玄武岩、凝灰岩、花岗岩等,岩石材质特性不同,对沥青混凝土有不同的影响因素。石料生产设备对石料加工质量有主要影响,目前业内常用的破碎机种类有圆锥破碎机、颚式破碎机、反击式破碎机、碎石整形机等,每种碎石机类型有不同的加工特征,就产出最佳石料形状的效能而言,反击式破碎机最优。

The quality of aggregate mainly depends on the rock,and the commonly used aggregates in asphalt pavement are limestone,basalt,tuff,granite and so on.The stone production equipment has a major impact on the quality of stone processing.At present,the main types of crushers commonly used are cone crusher,jaw crusher,impact crusher,stone shaping machine and so on.Each type of stone crusher has different processing characteristics.Among the above,the impact crusher ranks first in terms of the efficiency of producing the best stone shape.
