| Abstract: | Heating technology is the key of asphalt pavement HIR（Hot In-Place Recycling）,and heating process directly impacts the quality of construction.The asphalt pavement HIR,based on the hot air circulation heating mode,uses one dimensional unsteady heat conduction model to establish heat transfer temperature field,and then researches the heating level and the control of traveling velocity in asphalt pavement HIR.The results of field temperature measurements confirmed the direct relationship between heating level and traveling velocity.By the temperature measurement in real time and field direct it can effectively guide construction、improve operation efficiency、increase the fuel utilization and reduce cost. |
