Study on Properties of Cold Reclaimed Asphalt Mixture Based on Water Foaming Technology
In order to further study the advantages of foamed asphalt regeneration technology in RAP treatment and further evaluate the pavement performance of cold recycled foamed asphalt mixture scientifi-cally.Based on the engineering practice,the waste asphalt is recycled,and the cold reclaimed asphalt mix-ture is prepared by asphalt foaming technology,which is paved in the layer below the pavement structure.According to the characteristics of strength formation of foam asphalt mixture,the suitable foaming condi-tions of asphalt were analyzed,and the gradation design of cold reclaimed foam asphalt mixture was carried out.Through the study on the physical and mechanical properties of the foamed asphalt mixture and its practical properties,the results show that the foamed asphalt mixture has better mechanical strength and wa-ter stability,greater economic benefits,and guiding significance for engineering practice.
