Asphalt modification preparation method of ultrasonic pre-activated matrix asphalt
The invention relates to an asphalt modification preparation method of ultrasonic pre-activated matrix asphalt, and belongs to the technical field of road engineering. The content of the invention is to apply ultrasonic waves to a molten matrix asphalt for a period of time to produce an ultrasonically activated asphalt for further modification. The technical principle of the invention is as follows: ultrasonic waves can decompose macromolecules in molten matrix asphalt and generate free radicals, so that the chemical properties become more active, and the compatibility is enhanced. When the ultrasonic activated matrix asphalt and the modifier are mixed and melted for further modification processing, compared with non-activated matrix asphalt, more obvious chemical reaction or better molecular crosslinking can be generated, so that more satisfactory engineering performance can be obtained. In order to adapt to different engineering characteristics, an asphalt modification technology is always in development and transformation, and as a method for improving the performance of modified asphalt, the technology is necessary to be put forward.
本发明涉及一种超声波预活化基质沥青的沥青改性准备方法,属于道路工程技术领域。发明的内容是对熔融基质沥青施加一段时间的超声波,从而制成用于进一步改性的超声波活化沥青。本发明的技术原理是超声波可使熔融基质沥青中的大分子分解并产生自由基,从而化学性质变得更活跃、相容性增强。将超声波活化基质沥青与改性剂混融做进一步改性加工时,相对于采用未活化基质沥青会产生更显著的化学反应或更好的分子交联,从而可能获得更满意的工程性能。为适应不同的工程特性,沥青改性技术一直处于发展变革中,作为一种提高改性沥青性能的方法,本技术的提出有其必要性。
