• Abstract:
  The Virginia Department of Transportation (VDOT) initiated efforts to implement balanced mix design (BMD) in 2017, using 11 mixtures from a well-documented previous study in a benchmarking effort to select performance-related tests to use within the BMD framework and develop criteria for those tests. When these mixtures were produced and paved in 2015, sampling for extensive characterization was performed, and mixture locations were documented, providing important information to assess the in-service performance of the mixtures. The field projects associated with these benchmarking mixtures reached 8 years in service in 2023, providing the opportunity to assess performance and evaluate the suitability of the initial BMD cracking test criteria for design and production of 9.5-mm and 12.5-mm surface mixtures having A and D binder designations. The purpose of this study was to validate the suitability of the initial BMD cracking test criteria for design and reheated production specimens determined from the laboratory benchmark testing of 11 surface mixtures placed in 2015. Pavement condition surveys, falling weight deflectometer testing, field visits, and core testing were conducted to assess the mixture properties and pavement conditions after 8 years in service. Results were analyzed relative to the initial mixture properties and results of BMD benchmark testing to validate VDOT’s initial BMD cracking criteria.
