Research on Hot In-Place Recycling Technology of Asphalt Pavement

At present,a lot of asphalt pavement are in the state of repair and to be repaired.Recycling of asphalt pavement has become one of the main methods for the maintenance and transformation of asphalt pavement.Taking the hot in-place recycling technology as the study object,this paper studies the key technology,such as the survey and evaluation of the original road,the mix ratio design of recycling asphalt mixture,and the performance verification of recycling asphalt mixture.With a certain practical value for engineering,the research results can be effective in guiding the application of hot in-place recycling technology of asphalt pavement.
