Rosphalt 50 design means extra delivery, paving, compaction considerations on Tappan Zee Bridge

The automated asphalt extraction is an innovative, efficient, quick and safe solvent-based extraction of asphalt binder from asphalt mixtures, to characterize and control the quality of asphalt mixtures by measuring asphalt content and studying the aggregate gradations. This method is used for quality control and assurance, acceptance criteria, and research activities. The PaveAnalyzer is designed […]

Minimal Impact of Operator Variables when using the Automated Extraction Machine (PaveAnalyzer) for asphalt binder and filler extraction from Asphalt Mixtures (Preliminary Results)

WisDOT has implemented an approach known as “regressed air voids” as they work to improve pavement durability and cracking resistance by increasing the amount of binder in their asphalt mixtures.

Cargill partners with NCAT, MnROAD to demonstrate reliability of performance-based evaluations of high RAP mixes.

Illinois Flexibility Index Test (I-FIT) is an asphalt cracking test developed at the Illinois Center of Transportation. Here’s how to perform I-FIT.

If you want to reduce the variability of your gyratory specimen test results, you must improve the uniformity of the asphalt specimens you produce. Here are a few basic tips for compacting better asphalt specimens.

Having lab equipment in proper calibration gives you a better chance at proper measurements and testing results. Dan Ridolfi of Lastrada Partners, El Dorado Hills, California, stated the calibration and maintenance of lab equipment is just as important as the calibration and maintenance of the asphalt and aggregate equipment at the plant. “A producer never […]
