摘要:
为了分析沥青指标对排水性沥青混合料路用性能的影响,采用4种有代表性的改性沥青作为排水性沥青混合料的胶结料成型排水性混合料试件进行耐久性、强度性能、高温稳定性以及表面功能特性研究,并将试验结果与沥青指标进行对比分析.研究结果表明:60 ℃绝对粘度越大,排水性沥青混合料的抗老化性能及高温稳定性越好; 复数剪切粘度越大,排水性沥青混合料马歇尔稳定度越大; 粘韧性越大,排水性沥青混合料的劈裂强度和抗压强度越高; 胶结料类型对排水性沥青混合料表面功能特性影响较小.60 ℃绝对粘度、复数剪切粘度及粘韧性应该作为排水性沥青混合料胶结料选择的关键指标.
Abstract:
To analyze the influence of bitumen index on porous asphalt mixture performance, four kinds of representative bitumen were chosen to made different porous asphalt mixture. Durability, strength, high temperature stability and surface function of the four kinds of porous asphalt mixtures were tested, and the test results were compared with the bitumen index. The results show that with the increasing of 60 ℃ absolute viscosity, the high temperature stability and anti-aging property are improved; with the increasing of complex shear viscosity, the Marshall stability is higher; with the increasing of tenacity, the splitting strength and compressive strength are improved. The influence of bitumen on the surface function is minor. So 60 ℃ absolute viscosity, complex shear viscosity and tenacity are the key indexes of bitumen used to make porous asphalt.
