What are the testing procedures and methods used to classify soils, concrete mixes, and bituminous asphalt mixtures? Developed by expert Don Parnell, PE, the objective of the present online course is to outline common in-situ and laboratory tests used to distinguish the characteristics, properties, and gradations of various soil, concrete, and bituminous materials encountered in road construction.
