The Alaska Department of Transportation & Public Facilities is on the front line when it comes to promoting new technologies that give them continuous, full coverage asphalt pavement density testing for road paving projects. Continuous testing uses multiple inputs to look for failure zones and has a high probability of detecting defects before they lead […]

Editor’s Note: Read the February issue for findings from the Florida Department of Transportation’s experience with HFSTs over time. High friction surface treatments (HFST) provide enhanced pavement friction in critical safety locations such as horizontal curves and bridge decks. HFSTs are a thin layer of durable, high friction aggregate bonded to an existing pavement surface […]

Typically, standards voted on within the International Organization for Standardization (ISO) don’t impact the asphalt industry directly, according to Ray Brown, Ph.D., director emeritus at the National Center for Asphalt Technology (NCAT) at Auburn University. This truism has changed to some extent with the adoption of ISO 17025 calibration of measurement standards by the American […]

In the past, technology hadn’t paved the way for the successful use of ground tire rubber (GTR) in asphalt mix designs the way it has today. Now we have the means to grind tires “finer.” We can use advanced mixing chemicals that facilitate the use of wet process and dry crumb rubber modified asphalt cements […]
