DART Field Validation and Prototype Refinement

The National Cooperative Highway Research Program (NCHRP) Innovations Deserving Exploratory Analysis (IDEA) Final Report 193: DART Field Validation and Prototype Refinement documents a study to validate a field-ready prototype of the Duomorph Asphalt Rheology Tester (DART) as a low-cost and easy-to-use asphalt binder testing device. The DART system has the potential to provide a cost-effective way to monitor the uniformity or specification compliance of asphalt binder samples at various points along its supply chain. In this study, the research team performed validation tests to determine the effectiveness of the DART in production environments such as a paving job site, a field laboratory, and a binder production facility.
