Abstract:Highway structures ranging in age from 4 to 12 years and constructed from concretes incorporating high-range water reducers were surveyed for extent of surface scaling. Core samples were obtained from selected areas. Samples were subjected to petrographic analysis and linear traverse measurements. Air-void systems were characterized using standard ASTM C 457 parameters, chord distribution analysis, "Philleo" factors, and modal chord lengths. Statistical models relating degree of surface scaling to various combinations of parameters were tested. A three-parameter linear model incorporating spacing factor, water-to-cement ratio, and alteration of air voids in near-surface regions was found to yield the highest level of correlation with observed scaling.
