SYNTHESIS REPORT: D-CRACKING IN PORTLAND CEMENT CONCRETE PAVEMENTS

A comprehensive literature review was conducted to determine the mechanisms and testing procedures for D-cracking in portland cement concrete pavements. Beneficiation procedures were also investigated. The three general responses to freezing in the aggregate/paste system included elastic accommodation, high internal pressure, and high external pressure. It was found that the critical aggregate parameters influencing D-cracking were degree of saturation, maximum particle size, permeability, porosity, and pore size distribution. Evaluation of present laboratory testing procedures indicated that the ASTM C666, VPI slow-cool, Mercury Porosimetry, and Iowa Pore Index Tests correlated the best with field performance of concrete with respect to D-cracking.
