| Abstract: | A new testing procedure to estimate the low-temperature stiffness of the reclaimed asphalt pavement(RAP) binder was developed.In the testing procedure,the SuperpaveTM Bending Beam Rheometer(BBR) with special modifications and binder blending charts by Asphalt Institute were utilized.Modifications involved the development of a new kind of sample mold and different testing parameters were made to BBR testing procedure to capture the rheological properties of bitumen mortars produced by mixing fresh binder wit... |
