Design Analysis of Plant Mixed Hot Recycled Asphalt Mixture
In order to improve the performance of hot recycled asphalt pavement and achieve efficient utilization of recycled materials,this arti-cle takes a certain highway project as an example.Firstly,the selection of raw materials is analyzed,different RAP dosages are proposed,and the optimal asphalt dosage is determined.Then,rutting and small beam bending tests are conducted to analyze the changes in road performance of factory mixed hot recycled asphalt mixture.The results show that with the increase of RAP content,the high and low temperature perform-ance of the plant mixed hot recycled asphalt mixture changes significantly.
