Asphalt Mixture Quality Assurance Volumetric Properties and Laboratory Performance Related Tests: A Comparative Analysis
Many state departments of transportation are moving towards the assessment of laboratory performance related tests for asphalt mixture acceptance and mixture design. In the transition from volumetric to laboratory performance tests, the established criteria for volumetric quality acceptance needs to be evaluated against laboratory performance related properties. This study compares the volumetric and laboratory performance related properties for 27 asphalt mixtures that were placed in the field and the abilities of volumetric properties and laboratory performance related tests in predict performance. It was found that nearly all the mixtures passed the quality assurance volumetric specification, while several mixtures showed insufficient performance, as predicted by the Illinois Flexibility Index Test and Hamburg Wheel Track Test. This suggests that acceptable quality assurance volumetric factors may not guarantee satisfactory in-service performance. No specific trends were found using the asphalt mixture Glover-Rowe parameter, the Simplified Viscoelastic Continuum Damage DR and Saap parameters. However, all parameters were able to identify asphalt mixtures that may have a higher risk of deficient in-service performance. Finally, control charts were implemented and found useful to visually compare variability in properties and deviations from desired volumetric and performance related mixture attributes.
