Abstract

To explore the variation of hot mix plant recycling mixture design parameters and quality under the influence of RAP performance, represent index and factor level of RAP performance were determined, the variation of mix proportion design parameters was comprehensively analysised under different indexes and levels based on orthogonal test, and then the pavement performance was studyed. The result showed that: the fineness modulus of RAP had the most significant effect on design parameters, and then followed by asphalt content and aging degree. The aging degree of RAP had the most significant effect on mechanical properties of regeneration mixture. The high temperature properties were improved by a certain degree with a high aging degree, but then the water stability decreased significantly. And the high temperature properties of regeneration mixture decreased as the increasing of fineness modulus of RAP.
