Study on Compaction Characteristics of Foam Asphalt Cold Recycling Mixture under the Influence of Multiple Factors
Considering the compaction quality of foam asphalt cold recycling pavement directly affects pavement perfor-mance and durability.by measuring the change of void ratio and freeze-thaw splitting strength ratio of foam as-phalt cold recycled mixture under the influence of different factors(mixing time,mixing temperature,mold-ing temperature,different recycled materials),this paper on the compaction characteristics of foam asphalt cold recycled pavement.The results show that the best mixing time of foam asphalt cold recycling mixture is 1.5 min;Properly increasing the mixing and forming temperature is beneficial for improving the quality of the mixture forming;The specimen with 100%RBP has the best molding quality,while the specimen with RAP∶RBP=63∶37 has a slight decrease in volume and strength indicators compared to the former.
