This book was released on 2019 with total page 175 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation integrates and assesses in-service hot mix asphalt pavement data from several typically available but disconnected data sources to inform pavement policy and specification development. This in-service pavement data approach captures connected pavement data from different stages of pavement projects (e.g. mix design, construction, performance after completion) to better understand the relationship between actual in-service performance and mix design, structural design, and construction variables. The dissertation addresses the following research question: what is the value of the in-service pavement data approach in developing hot mix asphalt pavement policy and specifications? To test this question, the dissertation applies this approach using data from 2007 to 2017 to investigate several current Washington State Department of Transportation (WSDOT) research questions. Using the in-service pavement data approach, WSDOT pavement performance questions regarding (1) 3/8-inch versus 1/2-inch nominal maximum aggregate size (NMAS) mixtures, (2) the influence of elevated in-place density mixtures and other mixture characteristics, and (3) high-reclaimed asphalt pavement (RAP) (> 20%) versus up-to-20%-RAP mixtures are analyzed. High level findings include: (1) there is no statistical evidence to suggest a difference in performance between 3/8-inch and 1/2-inch NMAS mixtures; however, the cracking/rutting performance of 3/8-inch NMAS mixtures may be trending higher for older mixtures (ages 9-10); (2) there is no field evidence to suggest an apparent trend between elevated density and increased cracking/rutting performance; however, fine-graded mixture cracking performance may be trending higher than coarse-graded mixtures for older contracts (ages 8-10) and no contracts with a density of 94% or higher perform poorly ([less than or equal to] 50 cracking/rutting condition value); and (3) there is no statistical evidence to suggest a difference in performance between high-RAP (> 20%) and up-to-20%-RAP mixtures. Ultimately, the in-service pavement data approach is a repeatable framework that can be used to better understand the relationship between actual in-service performance and mix design, structural design, and construction variables. Additionally, it is generalizable to any field with large data sets on in-service pavements (e.g. airfields, highways, etc.). Towards this end, the in-service pavement data approach and high-level findings of the WSDOT case studies may be applicable to the U.S. Air Force pavement program.

Download or read book Quantifying the Impacts of Warm Mix Asphalt on Constructability and Performance written by and published by . This book was released on 2012 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: Joint efforts by the federal government and HMA industry to minimize cost and the environmental impacts of asphalt pavement construction have resulted in development of warm mix asphalt (WMA). This technology has gained such interest due to the potential to deliver pavements at lower temperatures, allowing for reduced energy consumption and emissions. In order to be effective WMA must meet the specified values of in-place density at reduced temperatures during construction and demonstrate sufficient resistance to pavement distresses while in-service. The overall objective of this research was to promote effective use of WMA through development of a procedure to recommend additive specific mixing and compaction temperature ranges that will provide adequate workability during construction, and an acceptable level of in-service performance. To pursue this objective an experiment was designed to evaluate the effects of various WMA technologies on the workability and performance properties of asphalt binders and mixtures using existing standards and new test methods developed during the study. The new test methods were pursued to better define the role of asphalt binder as a lubricant during compaction and to properly account for the effects of reduced production temperatures on asphalt binder performance and potential for moisture damage. Results found that use of WMA impacts both construction and performance properties. To account for these factors an evaluation framework to select appropriate production temperatures for WMA was introduced that is based on evaluation of mixture volumetrics, compactability, resistance to moisture damage, and rutting performance. Furthermore, to facilitate the mixture design and temperature selection process surrogate test methods to evaluate workability and performance properties of the asphalt binder as well as the integrity of the bond at the asphalt/binder aggregate interface were proposed and verified through relationships with mixture performance.

This book was released on 2011 with total page 111 pages. Available in PDF, EPUB and Kindle. Book excerpt: TRB's National Cooperative Highway Research Program (NCHRP) Report 691: Mix Design Practices for Warm-Mix Asphalt explores a mix design method tailored to the unique material properties of warm mix asphalt technologies. Warm mix asphalt (WMA) refers to asphalt concrete mixtures that are produced at temperatures approximately 50°F (28°C) or more cooler than typically used in the production of hot mix asphalt (HMA). The goal of WMA is to produce mixtures with similar strength, durability, and performance characteristics as HMA using substantially reduced production temperatures. There are important environmental and health benefits associated with reduced production temperatures including lower greenhouse gas emissions, lower fuel consumption, and reduced exposure of workers to asphalt fumes. Lower production temperatures can also potentially improve pavement performance by reducing binder aging, providing added time for mixture compaction, and allowing improved compaction during cold weather paving. Appendices to NCHRP Report 691 include the following. Appendices A, B, and D are included in the printed and PDF version of the report. Appendices C and E are available only online.

Download or read book Denver Metropolitan Area Asphalt Pavement Mix Design Recommendations written by Colorado Asphalt Pavement Association. Metro Mix Design Task Force and published by . This book was released on 1994 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: It has been estimated that over 60 asphalt mix designs are being specified by the various local governments and design consultants in the Denver metropolitan area. As material batches are ordered for delivery to these various agencies, the producers are required to constantly change their mixing formulations and plant operations. This constantly changing process results in inefficiencies in production time and cost to the buyer, as well as variability in the process. The problem is intensified when towns and communities order small amounts of material for a local street project. In March, 1994 a Government Forum was held in conjunction with the annual meeting of the Colorado Asphalt Pavement Association. At this forum, a decision was made to organize a Task Force to address this problem and provide recommendations for asphalt paving materials in the Denver Metropolitan area. This report presents the recommendations of that Task Force. The recommendations include gradation, asphalt cement type, additives, RAP, voids, and laboratory design properties. Four standard mixes were identified.
