Pavement Manual: Concrete Mix Design

The mix design is used to establish the proper proportioning of components (hydraulic cement, aggregates, water, pozzolans, and admixtures) in the mixture to achieve the specified properties. Significant concrete properties are strength, air content, slump, and the coefficient of thermal expansion (COTE).
