RECOMMENDED PERFORMANCE-RELATED SPECIFICATION FOR HOT-MIX ASPHALT CONSTRUCTION: RESULTS OF THE WESTRACK PROJECT

This report presents an overview of the WesTrack accelerated pavement testing experiment; a detailed description of its principal product, a performance-related specification for hot mix asphalt (HMA); and a summary of observations made and lessons learned during the course of this major program. The report will be of particular interest to personnel of state highway agencies, materials suppliers, and paving contractors with responsibility for specification and production of HMA and construction of asphalt pavements, and to others with an interest in accelerated pavement testing and development and implementation of performance-related specifications. The final report is organized as four separate parts in one volume. Part I is a detailed overview of the planning, construction, operation, and data collection of the WesTrack experiment. Part II describes the development, components, and features of the HMA performance-related specification and the software program "HMA Spec." Part III is a description of the WesTrack Database. Part IV presents key observations and lessons learned by the WesTrack team during all phases of the WesTrack project.
