The asphalt content in reclaimed asphalt pavement has a great influence on the pavement performance of recycled asphalt mixture. However, few people have studied the distribution of asphalt content and its effect on the performance of reclaimed asphalt pavement. In this paper, the above problems are studied by means of SEM analysis, combustion test and other scientific means, and it is pointed out that the adherence rate of fine aggregate is an important index to measure the distribution of reclaimed asphalt pavement, and has a significant effect on the pavement performance of recycled asphalt mixture. In addition, this paper also analyzes the factors that have an important effect on the adherence rate of fine aggregates.
