摘要
以Sasobit和Sasobit LM为研究对象,通过测取温拌沥青的粘温曲线及温拌沥青混合料的马歇尔试验对两者的降温效果和路用性能展开研究。结果表明:掺3%的Sasobit(Sasobit LM)能降低沥青混合料的拌合温度与碾压温度10℃(31℃)、9℃(29℃);Sasobit和Sasobit LM均能改善沥青混合料的高温性能,但Sasobit优于Sasobit LM;Sasobit对混合料的低温及水稳定性能有负面影响,而Sasobit LM对低温几乎没有影响,对水稳定性的影响小于前者。
Sasobit and Sasobit LM are the same type warm mix agent but different generation, cooling effect and the road performance properties between them are contrasted. The results show that mixing temperature and rolling temperature are reduced 10℃ and 9℃ when the dosage of Sasobit is 3%, but they are reduced 31℃and 29℃ in the same dosage of Sasobit LM. The high-temperature behavior of asphalt mixture is improved by both Sasobit and Sasobit LM, but Sasobit LM is better than Sasobit. Cryogenic property is more influenced by Sasobit than Sasobit LM. Water stability of asphalt mixture is reduced by both Sasobit and Sasobit LM, Sasobit LM is better than Sasobit.
