【 摘 要 】

A large amount of reclaimed asphalt pavements are produced every year, recycling and utilization of them as soon as possible can not only reduce the exploitation of natural aggregate resources and protect the natural ecological environment, but also help to solve the problem of reclaimed asphalt pavements. However, the complexity of structures and the lack of research on performance index have led to few successful applications about reclaimed asphalt pavements. In this paper the microstructure of reclaimed asphalt pavement was studied based on the X-ray CT scanning technology, by which the key factor in the evaluation of reclaimed asphalt pavement was found through analyzing the micrographs by VG Studio MAX image processing tool. The microstructure and evaluation index of reclaimed asphalt pavement provide a good foundation for application.
