Roller Compacted No-Fines Concrete Containing We Energies Fly Ash for Road Base Course Many problems associated with pavement failure are due to the pressure of water under rigid surface pavements. When high pressure from heavy traffic is applied on pavements in the presence of water, pumping occurs. Pumping causes erosion of the pavement base, as fines along with water are pumped out. The continued effect of pumping is a loss of support, leading to pavement failure. An open-graded permeable base is used to avoid such problems. The open-graded permeable base pavement system consists of a permeable base, separator layer and edge drainage. Permeable bases can be treated or untreated with cementitious binders. A demonstration project was designed to use an off-spec ASTM C618, Class F fly ash in the open-graded concrete base course and an ASTM C618 Class C fly ash in the concrete pavement for an internal road at the Port Washington Power Plant located in Port Washington, Wisconsin. The roadway cross section (see Figures 4-25 and 4-26) consisted of an initial layer of filter fabric installed to prevent fines from the subgrade moving up and blocking drainage in the base course, topped by a 6” thick layer of opengraded concrete base course and a 10 in. thick, high-volume fly ash concrete pavement. This pavement was designed in compliance with Wisconsin DOT standards, with the exception of using high-volume fly ash in the open-graded base, and concrete pavement. Underdrains, manholes and storm sewer piping were also installed as part of this project, to ensure proper functioning of the pavement system (32). The properties of fly ash and cement used in this project are shown on Table 4-41. The ASTM C618, Class F fly ash used on the project is offspecification with a very high LOI. The mixture proportions for the open-graded base course were composed of 160 lb./cu. yd. cement, 125 lb./cu. yd. fly ash, 81 lb./cu. yd. water, 2600 lb./cu. yd. ¾ in. coarse aggregate and no fine aggregate. The mixture proportions for high-volume fly ash concrete pavement included 300 lb./cu. yd. cement, 300 lb./cu. yd. Class C fly ash, 221 lb./cu. yd. water, 1200 lb./cu. yd. sand, 966 lb./cu. yd. ¾” aggregate and 966 lb./cu. yd. 1½” coarse aggregate. The water to cementitious materials ratio was maintained at about 0.37. We Energies 108 Coal Combustion Products Utilization Handbook
