ACI 325.14R-17

Concrete mixtures intended for pavements have purposes and desired characteristics that are different from other types of mixtures, such as structural or mass concrete. Thus, a guide for designing concrete mixtures specific to paving, such as highways, streets, airfields, and parking lots, is necessary. This guide describes a method for designing mixtures and selecting trial mixture proportions for hydraulic-cement concrete made with and without supplementary cementitious materials, chemical admixtures, and fibers. The guide provides a method that focuses on designing the concrete mixture in the context of pavement structural design, concrete production, construction operations, and the environment in which the pavement will reside. Trial mixture proportions are for concrete consisting of normalweight aggregates and concrete with workability suitable for various types of pavement construction, such as slipform, fixed-form, and laser-guided screeding.
