Theses and Dissertations
This study was initiated to evaluate the impact of aging and High Polymer Modified Asphalt (HPMA) binders containing a bio-based-oil softening agent (SA) on the rutting, cracking, and durability of asphalt mixtures. One control asphalt binder (PG 52-34), Styrene-Butadiene-Styrene (SBS) polymer modifier, and corn-oil SA were used to produce four asphalt mixtures including a control prepared using PG 52-34 binder and three modified mixtures were produced by blending PG 52-34 binder with different dosages of SBS and SA. The mixtures were tested using the Dynamic Complex Modulus (|E*|), Hamburg Wheel Tracking Device (HWTD), Flow Number (FN), Indirect Tension Cracking Test …
