Abstract

This paper reports the results of research performed in the development and use of high volumes of Class C and Class F fly ash in concrete mixes for roadway paving projects.

Mix proportions were developed for paving roadway concrete with 20 and 50% Class C fly ash and 40% Class F fly ash replacements for Portland cement. These mixes were used to demonstrate their potential for highway paving work. Actual application test results are presented including fresh concrete data, compressive strength, flexural strength, tensile strength, and freezing and thawing durability data.

The test results indicate that high volumes of Class C and Class F fly ash can be used to produce high-quality pavements in concrete with excellent performance.
