摘要
A hot recycling heating method for old asphalt mixture, includes the steps of: mixing old asphalt mixture with hot asphalt, with the temperature of the hot asphalt being higher than the temperature of the old asphalt mixture, but not higher than the standard temperature of heating aspha and heating the old asphalt mixture by heat exchange between the hot asphalt and the old asphalt mixture. The method is essentially described as mixing the old asphalt mixture with the hot asphalt to result in a new mixture of the old asphalt mixture and the hot asphalt, thus the purpose of heating the old asphalt mixture by a gapless heat exchange environment between the hot asphalt and the old asphalt is reached; in addition, the method revolutionizes the traditional recycling heating modes for old asphalt, significantly reduces the degree of degradation in the performance of the old asphalt mixture during a heating process, improves the pavement performance of the old asphalt mixture, greatly reduces generation and emission of asphalt fumes during a heating process, and avoids or reduces pollution and damage to the natural environment.
