Evaluation of Pyrolized Carbon Black From Scrap Tires as an Additive in Hot Mix Asphalt
The main objective of this study is to evaluate the viability of using Pyrolized Carbon Black (CBp) derived from waste tires as a reinforcing agent in asphalt mixtures.  
Commercial Carbon Black (CB) has been previously shown to reduce the rutting resistance, the...

Review of Fine Aggregate Angularity Requirements in Superpave
Superpave aggregate qualification includes the fine aggregate angularity (FAA).  The numerical value of the FAA is the mineral aggregate of the loosely packed fine
aggregate.  Use of FAA has been predicated on the philosophy that...

Using Pyrolized Carbon Black (PCB) from Waste Tires in Asphalt Pavements (Part I: Limestone Aggregate) - Final Report
This study presents the viability of using PCB as an additive in hot mix asphalt concrete.  Different ratios of PCB (5%, 10%, 15%, 20% by weight of asphalt) were
blended with two grades of asphalt (AC-10 & AC-20).  The complete behaviors of the PCB modified...
