由于重型车辆日益增多,要求沥青路面具有更高的承载和抗磨能力,具有在重荷载和高剪切力下抗变形能力,抗滑性能;要求沥青材料具有良好的低温塑性、抗老化性、耐久性;对沥青含蜡量、粘附性等提出了更高的要求。为了适应公路交通运输的发展,近年来改性沥青的发展非常迅速。 Due to the increasing number of heavy vehicles, asphalt pavement is required to have higher bearing and wear resistance, anti-deformation ability and anti-skid performance under heavy load and high shear force. Asphalt materials are required to have good low temperature plasticity, aging resistance, Durability; asphalt content, adhesion, etc. put forward higher requirements. In order to adapt to the development of highway transportation, the development of modified asphalt has been very rapid in recent years.
