- Abstract:
- In order to study the influence of different foam asphalt content and content of milling material fromasphalt pavement ( RAP ) on splitting strength of the foam asphalt recycled mix, two different milling materialfrom asphalt pavement which will be called RAP, and RAP, were chosen. The old material volume which is respectively 0%,20%,40%,60%,80% and the foam asphalt content which is 2%,2.5%,3% ,3.5% ,4%were mixed, and mixed foamed asphalt recycled mix , molded piece, determined dry and wet splitting strength( ITS) and residual spliting strength ratio ( TSR ). The results showed when old material content proportionwas a certain condition, the foam asphalt content of mixture reached an optimum value. As the RAP contentincreased gradually, optimum asphalt content of foamed asphalt recycled mix was reduced gradually, and thevalue changed from 3.5% when RAP was0 to 2% when RAP was 80%. As the RAP content increased, drand wet ITS of foamed asphalt recycled mix decreased, but TSR increased.
