摘要
•Various preheating levels of Hot In-place Recycling (HIR) were simulated by temperature and heating time in laboratory.•Effect of preheating to the recycled asphalt mixture was evaluated through performance tests.•Workability of recycled material was assessed by gyratory compacter attached program.•Bond strength between recycled layer and aged materials was tested through self-developed direct shear tester.
