[0002] my country's highway construction, especially high-grade highway construction, has developed rapidly, and asphalt pavement is widely used in highway construction. Nowadays, many old asphalt pavements are facing renovation. Common asphalt regeneration technology usually uses a combustion furnace to heat the old asphalt blocks and the regeneration agent together. A large amount of heat will be generated in the combustion furnace to melt the asphalt blocks and mix them with the regeneration agent to achieve the purpose of asphalt regeneration. During the asphalt regeneration process, different batches of asphalt samples need to be tested. The heating method is usually used to bake the asphalt samples to calculate the remaining content. During the detection process, a heating furnace needs to be used in the laboratory to heat the samples. The asphalt regeneration and content detection processes both generate heat. Such a detection process cannot utilize the waste heat generated by the asphalt regeneration furnace, resulting in a certain degree of energy waste.
