A review of the literature together with filed experience gained in Texas has resulted in a modification of the Federal Highway Administrtion design method for open-graded asphalt friction courses. The extension of this procedure involved the development of design curves for synthetic aggregate mixtures over a range of air void contents. Field surveys were made in four districts of the Texas Highway Department where open-graded bituminous mixes have been placed as trial sections and/or contract jobs. Data collected include a) freeze-thaw of field cores, b) Mays Ride Meter measurements, c) texture measurements by two methods, d) water outflow measurements, e) frictional performance, f) construction guides, and g) types of expected or observed distress with suggestions for remedial action. /Author/
