SBS改性和博尼维纤维加强沥青混合料路用性能试验研究

采用了SBS改性和博尼维纤维加强沥青混合料两种措施,制作了普通密级配沥青混凝土、SBS改性沥青混凝土、普通沥青混凝土掺加纤维及SBS改性沥青混凝土掺加纤维等4种沥青混合料。通过室内对这4种沥青混合料的高温稳定性、低温抗裂性能、抗老化性及水稳定性的测定,对改性沥青及纤维加强的效果与路用性能指标进行了全面的试验研究,得出了SBS改性沥青及纤维加强的作用效果。

Research on Pavement Performance of Modified Asphalt Concrete

The asphalt modified by SBS and the concrete reinforced by fibers are adopted,four types of asphalt concretes are made,which are the general asphalt concrete,SBS modified asphalt concrete,the general asphalt concrete reinforced by Bonifibers and SBS modified asphalt concrete reinforced by Bonifibers.The stability under high temperature,the anti-crack ability under low temperature,the anti-aging ability and the water resistance are tested for the four types of asphalt concretes in lab.The effect of modified asphalt and fiber reinforcement on the road performance is comprehensively researched by testing.The effect of asphalt modified by SBS and concrete reinforced by fibers is concluded.
