Optimization of RAP Material Milling and Recycling Process Based on OWA Operator
Due to the late start of domestic research on milling technology and lack of relevant technical experience,the setting of milling process parameters is often determined according to construction experience in the previous milling process of old asphalt pavements,subjective factors are strong,which affects the quality of RAP material. In order to solve the problem of poor quality of RAP material due to improper milling process,this paper adopts the Ordered Weighted average operator to comprehensively consider the degree of refinement and artificial bone With two indexes of material rate,the optimal milling speed of different mixtures was studied,and the milling process parameters of different asphalt mixtures were optimized. The results show that:① the optimal milling speed of AK-13 is 15m/min;② the optimal milling speed of AK-16 is 12m/min;③ the optimal milling speed of AC-20 is 7m/min.
