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。
SBS modified and Bonifiber fiber reinforced asphalt mixture were used to prepare four kinds of asphalt, including ordinary dense graded asphalt, SBS modified asphalt concrete, common asphalt concrete mixed fiber and SBS modified asphalt concrete mixed fiber Mixture. Through the indoor tests on the high temperature stability, low temperature crack resistance, aging resistance and water stability of the four kinds of asphalt mixtures, the comprehensive experimental research on the effect of the modified asphalt and the fiber reinforcement and the road performance indexes was carried out. Obtained SBS modified asphalt and fiber to enhance the effect.
