A 2.388 mile section of four lane highway in Louisville, Kentucky, was selected for an experimental fly ash concrete pavement installation. The project was divided into three sections: a control section and two experimental sections containing 94 and 140 lb of fly ash per cubic yard, respectively. The solid volume of fly ash in excess of that required to replace one sack of cement was considered as fine aggregate. The water was adjusted to provide slump of approximately 2 1/2 inches and an air-entraining admixture was proportioned at the mixer to provide an air content of approximately 4.5 percent. Early strengths for concrete placed in the experimental sections were lower than those for concrete placed in the control section. On the basis of limited 3 month age compressive strength tests, a gain in strength at later ages was achieved through the use of fly ash. No reduction in water requirement was gained through the addition of fly ash.
