ACI 325.14R-17 PDF Download

ACI 325.14R-17 is a guide that specifically focuses on the design and proportioning of concrete mixtures for pavements. It addresses the unique requirements and desired characteristics of concrete used in highways, streets, airfields, and parking lots. The guide provides a comprehensive method for designing concrete mixtures, taking into consideration factors such as pavement structural design, concrete production, construction operations, and the environmental conditions where the pavement will be located.

The guide offers trial mixture proportions for different types of pavement construction, including slipform, fixed-form, and laser-guided screeding. It evaluates the performance potential of the proportions in terms of various aspects such as mixing, transporting, placing, screeding and consolidating, finishing, texturing, and time-of-setting. Additionally, it considers important hardened concrete performance parameters such as strength, durability, abrasion resistance, skid resistance, smoothness, and dimensional and shape stability.

The standard also includes methods for checking material compatibility in specific construction environments and optimizing aggregate grading. However, it does not cover special concrete pavement mixtures like pervious concrete or roller-compacted concrete.

It is worth noting that this is a dual-unit document, although inch-pound and SI units may not be exact equivalents. Therefore, it is recommended to use one system independently of the other.
