摘要为提高常温拌合乳化沥青混合料的工作性能和路用性能,采用拌合试验、劈裂试验及间接拉伸疲劳试验研究了水固化型聚氨酯预聚体改性乳化沥青混合料的拌合和易性及力学性能。试验表明,水固化型聚氨酯预聚体改性乳化沥青混合料具有良好的拌合和易性,以及优于SBR改性乳化沥青混合料的拌和效果,同时水固化型聚氨酯预聚体的加入也有利于乳化沥青破乳后混合料早期强度的形成,从而提高乳化沥青混合料的早期劈裂强度及水稳定性。此外,为使该沥青混合料具有良好的抗疲劳性能,推荐聚氨酯预聚体改性材料的掺量为总用水量的40%~50%。研究表明,临界应变能密度与抗疲劳评价指标具有显著的相关性,在有限的试验条件下,可以通过综合力学性能评价指标(临界应变能密度)可以快速分析乳化沥青混合料的抗裂能力及抗疲劳性能,有利于指导室内评价研究。

Abstract: In order to improve the working performance and road performance of emulsified asphalt mixture at room temperature,the mixing test, splitting test and indirect tensile fatigue test were used to study the mixing workability and mechanical properties of the water-curable polyurethane prepolymer modified emulsified asphalt mixture. Tests show that the water-curable polyurethane prepolymer modified emulsified asphalt mixture has good mixing, and better mixing effect than the SBR modified emulsified asphalt mixture. At the same time, the addition of water-curable polyurethane prepolymer is also conducive to the formation of early strength of emulsified asphalt mixture after demulsification, the early splitting strength and water stability of emulsified asphalt mixture are improved. In order to make it have good anti-fatigue performance, it is recommended that the amount of polyurethane prepolymer modified material is 40wt%—50wt% of the quality of asphalt. The research shows that the critical strain energy density has a significant correlation with the anti-fatigue evaluation index. Under the limited test environment, the comprehensive mechanical performance evaluation index critical strain energy density can quickly analyze the crack resistance of emulsified asphalt ability and anti-fatigue performance, it is helpful to guide indoor evaluation research.
