This investigation was conducted to develop and demonstrate permeable base course materials using coal combustion products (CCPs) for highways, roadways, and airfield pavements. Three types of CCPs - two high-carbons, high-sulfate flue-gas desulfurization (FGD) by-products, and a variable-carbon fly ash - were evaluated for no-fines or low-fines concrete as a permeable base material. This report summarizes the initial work completed for this two-year project. A total of 56 mixtures were proportioned and manufactured in the laboratory. Mixture proportions for the base course materials were developed using a two-step experimental optimization process. Specimens from each mixture were made using rollercompacted concrete (RCC) technology in accordance with ASTM C 1435 Based on the mixture proportions established in the laboratory, four prototype open-graded base course mixtures containing one source of CCP were manufactured at a commercial ready-mixed concrete plant.
