Abstract:"The primary objective of this research study was to evaluate the fracture mechanics properties of HMA concrete for Superpave mixtures. An experimental program was performed on asphalt mixtures with various types of materials. The laboratory testing program was developed by applying the viscoelastic fracture mechanics-based framework that apperared to be capable of describing the whole mechanical properties of HMA according to past research studies at University of Florida. The goals for these experiments are to evaluate the effect of aggregate type, the effect of coarse aggregate gradation adjustment to control mix designs, and the effect of SBS polymer on fracture mechanics properties of HMA mixtures"--Technical report documentation p.
