Abstract
In the construction of asphalt pavement recycling technology, hot air circulating type heating method is one of the more widely used methods. Therefore, the research on the heating effect of this method in mobile asphalt pavement maintenance equipment is of great significance to improve the heat utilization rate of the equipment and optimize the hot air system structure of the equipment. This paper takes an area of the heating wall as the research object, and uses the contact temperature measuring method to test the heating effect in different areas and depths.The results show that there is almost no temperature change after the effective depth of hot air heating for asphalt pavement heating is 30mm and 50mm, and the temperature measuring method by indirectly monitoring smoke and air temperature to heat asphalt pavement is not very accurate, so a more direct and accurate contact temperature measuring method can be explored.
