Abstract:

The objective of this study was to evaluate the influence of production variability on performance test results to determine if mixtures balanced during design could become unbalanced during production. Fourteen currently accepted mixture designs, 10 BMD mixtures and 4 Superpave mixtures (to serve as a comparison between current standards and BMD designs), were recreated in the laboratory. Additionally, the mixes were adjusted to produce coarse and fine gradations and high and low binder contents according to currently accepted tolerance limits to simulate production variability. Two interaction mixtures assessing changes in gradation and binder content were evaluated as well as two critically aged mixtures.
