The 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 performa
