In all applications, however, the desired end result is to have consistent material gradation behind the machine. The team at BOMAG Americas, Ridgeway, South Carolina, has incorporated extra breaker bar assemblies and an additional variable-position […]

Researchers at the National Center for Asphalt Technology (NCAT) at Auburn University in Alabama study failed as well as successful experimental sections on their pavement test track. The latest three-year research cycle at the track includes a special focus group of pavement sections they hope will fail. The reason: they learn as much from evaluating […]
