摘要： A method for evaluating damage-healing characteristics of paving asphalt based on energetics principle includes: obtaining a numerical integral AH of a stored pseudo strain energy required by asphalt to compensate damage-healing to loading times and obtaining local life compensation ΔN of the asphalt benefiting from damage-healing characteristics; calculating an average stored pseudo strain energy QH of the asphalt according to the following formula:

and evaluating the asphalt damage-healing characteristics according to the average stored pseudo strain energy QH of the asphalt. This method is based on the evolution law of the average stored pseudo strain energy required to compensate the damage-healing to explore the damage-healing characteristics of asphalt. As a characteristic index of materials, this energy evaluation index has nothing to do with the damage state and the rest periods, but only depends on the strain load, which improves the testing efficiency.-
