Calculation of Shear Rate on Asphalt Binder in The Superpave Gyratory Compactor
Asphalt Superpave Superpave gyratory compactor Viscosity Mixing Compaction
2009/10/12
Most modified asphalt binders show pseudoplastic characteristics and their viscosity values depend on shear rate. The calculation of compaction temperatures for Superpave gyratory compactors (SGCs) de...
Reinforcing Effects of Carbon Black on Asphalt Binder for Pavement
Asphalt binder Reinforcement Carbon black SHRP
2009/7/24
Carbon black, used as a reinforcing filler for rubber materials, was evaluated for asphalt binders in pavements. Carbon black added to straight asphalt within 20 wt% caused an increase in the elastic...
Mechanism of Asphalt Binder Aging by Ultraviolet Irradiation and Aging Resistance by Adding Carbon Black
Asphalt binder Ultraviolet irradiation Aging Carbon black Carbonyl group
2009/7/24
The components of asphalt binders were separately irradiated with ultraviolet (UV) rays to examine the aging mechanism. The results confirmed that saturates are converted to resins and asphaltenes, r...
