Open Graded Friction Courses for HMA Pavements

A laboratory study was conducted to evaluate Open Graded Friction Course (OGFC) mixtures meeting current Mississippi specifications. In addition, materials included a second 12.5 mm gradation and an asphalt rubber binder. The additional 12.5mm gradation was selected to evaluate application of the asphalt rubber binder. Specifically, the asphalt rubber OGFC was included for its potential of noise reduction. Factors in the study included gravel and gravel/limestone aggregate combinations, three gradations, and two asphalt binders, PG 76-22 and Ground Tire rubber (GTR) PG 76-22. Laboratory tests were conducted to evaluate the effect of design mixtures relative to aggregate type, gradation, and binder type. Tests included two permeability tests, MT-84 and White falling head test; Stripping, MT-63; sound absorption, ASTM E1050; dynamic modulus, AASHTO TP 62; and interface bond strength, direct shear.
