Office of Preconstruction, Construction, and PavementsApplied Pavement Technology, Inc.Yu, TomFederal Highway AdministrationThe variability of a concrete paving mixture can have a significant impact on the performance of the concrete pavement and impact its overall service life. Mixture variability can lead to inconsistent workability, poor consolidation, built-in roughness, and areas of weaker, less durable concrete, all of which can negatively affect pavement performance (Fick et al. 2012). Well-defined and implemented field control of concrete paving mixtures is extremely important to produce, deliver, and place a consistent concrete pavement mixture that meets design criteria and increases the chance of achieving durability goals. This Tech Brief summarizes guidance on the concrete-making process from batching through placement on grade.88
