摘　　要： 各种各样的改性剂在高等级路面中被广泛应用,因而改性剂优选成为一个问题。采用二级模糊综合评判的方法对此进行了研究。针对中国南方高温、多雨的特点,对基质沥青混合料、路孚8000改性沥青混合料、TPS改性沥青混合料和SBS改性沥青混合料进行了路用性能试验,包括高温稳定性、低温抗裂性、水稳定性和抗疲劳性能试验;并应用模糊综合评判的方法进行性能评价,得到了定量的综合路用性能排序。结果显示模糊综合评判是优选改性剂的有效方法。 Kinds of additives are used in the surface course of highway. Thus the choice of ;additives has been a problem.The comprehensive judgment method in fuzzy mathematics was applied to resolve this problem. In connection with the climate of high tempcrature, heavy rains of south of china, the pavement performance tests of substrate bitumen mixes, Luft 8000, TPS and SBS modified asphalt mixes, including high temperature stability, low temperature performance, water stabilily and anti-fatigue performance, are carried out. Performanccs of these asphah mixtures with additives were assessed by the method of fuzzy comprehensive evaluation. Then quantificational sequence of comprehensive pavement performance could be showed.Result indicates that fuzzy comprehensive evaluation is an available means of the choice of additivos.
