Laboratory

The Sustainable Asphalt Materials (SAM) Laboratory was initiated in 2017, located in Room 146 of Science Laboratory Building (old engineering building).

Address: 6041 USA Dr N., Mobile AL, 36608

The SAM laboratory are adequate for performing all asphalt binders, aggregates, and asphalt mixture testing, including:
