4. Concrete mixtures with 35% to 55% fly ash to total cementitious material ratio exhibited excellent resistance to water permeability at 91 day age. 5. The resistance to chloride ion permeability increased as the concrete aged. At the age of one year, all the fly ash mixtures showed very low chloride ion permeability. 6. Air content had little effect on air, water and chloride ion permeability of concrete, within the test limits. Figure 4–18: Sussex Corporate Center boulevard entrance paved with high-volume fly ash concrete High-Volume Fly Ash Concrete - Pilot Projects Several pilot projects were completed as part of the research work to demonstrate and better understand the actual performance of We Energies coal combustion products. All the pilot projects were very successful, and have been in service for several years. The following are examples of such projects. Sussex Corporate Center Pilot Pavements at the Sussex Corporate Center, village of Sussex, Wisconsin, were constructed using high-volume fly ash concrete in 1995. Concrete pavements do not require major maintenance for 30 to 50 years, while asphalt pavements typically last only 10-15 years, after which they are generally milled and surfaced or replaced.

Tax Incremental Financing (TIF) was used as a means of encouraging investment on this project. If asphalt pavement is constructed using TIF and it needs replacement in 10 or 15 years, that work will not be funded by most TIF districts. Since the decision to construct concrete pavement using TIF funds was made, there was no reason to worry about finding alternate financing for future pavement maintenance (29). The Sussex Corporate Center is a 221-acre business park development for small light-industrial business offices and includes approximately 20 commercial parcels. High-volume fly ash concrete was used for paving approximately 4,220 linear feet of dual 28-foot lane divided concrete boulevard and 4210 linear feet of 36-foot wide concrete pavements placed for the corporate center roadways. 9-inch thick concrete pavements were placed over a 6-inch crushed limestone base course. Concrete Pavement Mixture The concrete mixture was designed for a minimum of 4,000 psi compressive strength at 28 days. ASTM C618, Class C fly ash from Pleasant Prairie Power Plant was used on the project. Table 4-24 gives the mixture design for the concrete pavement. Table 4-24: Sussex Corporate Center Concrete Mixture Proportions Material Description Cement Type 1 Class C Fly Ash Sand Stone (#1 and #2) Water (total) Air Entrainment Water Reducer Quantity Per Cubic Yard 360 lbs. 214 lbs. 1,410 lbs. 1,800 lbs. ± 21 gal. 20 oz. As needed for workability The fly ash used met the standards of ASTM C618 and the cement met ASTM C150 Type 1 standards. Table 4-25 is a comparison between the Wisconsin Department of Transportation pavement specification and this paving mixture containing 40% fly ash. 89 We Energies Coal Combustion Products Utilization Handbook
