| 摘要： | This research aimed to evaluate the effect of variability in the RAP Statistical inferenceson the recycled binder limits by examining extensively the rheological properties of recycled binders from different RAP sources. RAP stockpiles from different geographical regions were selected and the recycled binder extracted from RAP was characterized using the Dynamic Shear Rheometer and binder limits determined to identify differences among the stockpiles. Statistical inferences were derived from the rheological properties of the different RAP binders and the binder limits obtained for different stockpiles were used to develop draft specifications to select the optimum amount of recycled materials based on the variability between and within stockpiles. Blending charts were developed for selected virgin binders and RAP binder samples and the RAP binder limits were derived. Also the report describes the procedures for developing blending charts and deriving RAP binder limits. |
