2 Project Partnership within FHWA Brad Neitzke, Federal Lands Highway Richard Duval, FHWA Turner Fairbank Highway Research Center
3 HMA Progression of Specifications 1960 s Federal Specifications Broadband gradation requirements Asphalt content by weight during mixing Asphalt cement by certification Methods of manufacture 3
4 HMA Progression of Specifications 1970 s Federal Specifications Gradation target values and tolerances Asphalt content target and tolerance Density Limited asphalt cement testing (primarily certification) 4
5 HMA Progression of Specifications 1980 s Federal Specifications Gradation with target value and tolerance Asphalt content with target value and tolerance Density Thickness Asphalt cement testing limited certification Statistical acceptance Pay lots and pay factors 5
6 HMA Progression of Specifications 1990 s Federal Specifications Gradation with target value and tolerance Asphalt content with target value and tolerance Density Asphalt binder testing (Performance Grades) Smoothness measurement with pay adjustments (Profilograph) Contractor testing with agency verification Statistical acceptance Pay lots and pay factors 6
7 HMA Progression of Specifications 2000 s Federal Specifications Asphalt mixture volumetrics (VMA, Air Voids, VFA) Asphalt content with target value and tolerance Minimum VMA Density Asphalt binder testing (Performance Grades) Smoothness measurement with pay adjustments (Inertial Profilers) Contractor testing with agency verification Statistical acceptance Pay lots and pay factors 7
8 Additional Mixture Tests Immersion Compression Tensile Strength Ratio Hamburg Wheel Track Testing Asphalt Pavement Analyzer TSRST 8
9 Performance Specifications Can we Optimize and Improve Performance? Determine how volumetrics relate to performance and pavement life? Develop quality adjusted pay factors that reflect as-constructed pavement life? 9 9
