Abstract:

The main objective of this research was to evaluate characteristics of milled Recycled Asphalt ; Pavements (RAP) collected from selected milled roadways in Kansas. The RAP was collected from three ; selected milled roadways including K-25 in Grant County, K-25 in Logan County, and US-83 in Scott ; County. The aggregates were extracted from RAP, and tested for characteristics including gradation, specific ; gravity, Fine Aggregate Angularity (FAA), Coarse Aggregate Angularity (CAA), flat and elongation (F&E), ; and Los Angeles Abrasion (LA) values. Binder from each source was extracted from the RAP, and recovered ; for a PG grade testing. The changes in the properties of aggregates after milling from the roadways as ; compared with the original aggregates are discussed. The variability of RAP aggregates was analyzed. In ; addition, the differences between the properties of aggregates extracted by centrifuge and ignition methods ; are compared.
