Abstract

Huge accumulations of Recycled asphalt pavement (RAP), scarcity of bitumen obtained from natural resources, RAP causing environmental pollution, and increased construction of flexible pavement all over the world led the researchers to reuse the improved aged bitumen by modifiers. Hence, in this research, the reclaimed aged asphalt improved by ABS (5% weight of virgin bitumen) was partially replaced by virgin bitumen (10 to 60% with an increment of 10%) used in the asphalt mix, and mechanical properties such as stability, flow, rutting resistance, fatigue life, Indirect Tensile strength, and resilient modulus were investigated. The research concluded that the aged reclaimed asphalt containing 5% ABS can be partially replaced up to 30% by conventional virgin bitumen, exhibiting better performance without compromising the mechanical properties of the asphalt mix.
含丙烯腈-丁二烯-苯乙烯(ABS)再生沥青混合料的力学性能
再生沥青路面(RAP)的大量积累、天然资源沥青的稀缺、RAP造成的环境污染以及世界各地柔性路面建设的增加,促使研究人员通过改性剂对改性后的老化沥青进行再利用。因此,本研究将ABS(原沥青重量的5%)改性的再生老化沥青部分替换为原沥青(10% ~ 60%,增量10%)用于沥青混合料中,对其稳定性、流动性、抗车辙性、疲劳寿命、间接拉伸强度、弹性模量等力学性能进行了研究。研究得出结论,含有5% ABS的老化再生沥青可以部分取代30%的传统原始沥青,在不影响沥青混合料机械性能的情况下表现出更好的性能。
