Analysis of the trend in evolution of multilevel mechanical properties of solvent-based cold mixed liquid asphalt and mixture

This paper primarily analyzes the change in performance of liquid asphalt and its mixture in each stage and proposes suggestions for fabricating liquid asphalt mixtures in cold weather. The results of GPC and SEM can explain the reasons for the increase in viscosity and strength of liquid asphalt after curing. In addition, the generalized time-temperature equivalence principle is used to predict the performance changes of liquid asphalt, asphalt mortar, asphalt mastic and asphalt mixtures under different curing conditions. The results show that increasing the filler content improves the deformation resistance of liquid asphalt mixtures. The low-temperature performance of liquid asphalt mixtures is outstanding. During construction in cold weather, liquid asphalt or its mixtures can be used after curing at 60 ~& nbsp;110 C for 1 ~& nbsp;10 h. These parameters can ensure the strength of cold mixed liquid asphalt mixtures in low-temperature environments, and roads repaired with this asphalt can be rapidly opened to traffic.
