Available in PDF, EPUB and Kindle. Book excerpt: Currently, asphalt mixtures are designed using volumetric concepts to determine optimum asphalt content levels with no means of verifying mixture performance prior to field production and placement. A new design methodology called Balanced Mixture Design (BMD) promotes the use of evaluating and design asphalt mixture using rutting and fatigue cracking methods and criteria to achieve an optimum asphalt content that will result in an asphalt mixture performing well in rutting and fatigue cracking scenarios -thereby "balancing" the asphalt mixture performance. A study was conducted using approved New York State Department of Transportation (NYSDOT) approved asphalt mixtures within this BMD procedure. The approved asphalt mixtures were previously designed using volumetric concepts, allowing for a comparison between performance-based design procedures (BMD) and volumetric procedures. The study showed that of the eleven (11) asphalt mixtures evaluated, six (6) of the asphalt mixtures were found to not meet the BMD fatigue cracking based minimum asphalt content. None of the approved asphalt mixtures failed the rutting performance criteria. The data generated in the study also enabled for the recommendation of performance criteria for the High Temperature IDT Strength test for rutting and IDEAL-CT Index test for fatigue cracking.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainability is a cornerstone of today0́9s engineering world. Warm mix asphalt (WMA) and reclaimed asphalt pavement (RAP) are the most prominent sustainable materials in asphalt concrete pavements. WMA is a not a new concept, however new innovations and increased usage of WMA has been spurred by the increased focus on sustainable infrastructure systems. WMA enables reduced production temperatures through the use of wax, water, or other chemical packages. The effects of reduced production temperatures include fuel use and emissions reductions, improved compaction, and possible RAP concentration increases. RAP is the primary recycled product of the aged asphalt concrete pavements and its use leads to reductions in virgin aggregate and asphalt demand. However, significant performance issues can stem from the individual integration of WMA or RAP materials in asphalt concrete. In particular, WMA technologies can increase moisture and rutting susceptibility while RAP significantly increases the stiffness of the resulting mixture. Consequently, quality performance of sustainable asphalt pavements may require the combined use of WMA and RAP to produce mixtures with sufficient stiffness and moisture and fracture resistance. This study evaluates the potential of WMA technologies and their integration with RAP. Initially, an extensive literature review was completed to understand the advantages, disadvantages, and past field and lab performance of WMA and RAP mixtures. Rotational viscometer and bending beam rheometer tests were then used to evaluate Sasobit, Evotherm M1, and Advera WMA modified and unmodified binders. Finally, virgin and 45% RAP mixtures were designed and tested to examine the rutting, moisture, and fracture resistance of WMA and HMA mixtures. The results of this experiment provided several key observations. First, viscosity reductions may not be the primary cause for the availability of reduced production temperatures for WMA technologies. Second, WMA additive properties have a significant effect upon fracture, moisture, and rutting resistance. Furthermore, the addition of RAP to WMA mixtures improved the rutting and moisture sensitivity performance as characterized in the Hamburg and Tensile Strength Ratio testing procedures.

Book excerpt: In this research, a systematic performance tests of asphalt mixtures of different types of gradations with various asphalt contents have been carried out to analyze the following characteristics of the asphalt mixture:1)high temperature rutting. 2)low temperature cracking resistance. 3)moisture stability. 4)fatigue resistance. 5)skid resistance. combined with previous studies, a system of proportioning design method of asphalt mixture is established to suit for applying in various climate areas of China. A recommended optimal proportions of asphalt mixture for each of the climate areas is also presented in this study. While the high-temperature rutting is taken as the control factor for the climate area where yearly extreme low temperature is higher than -21.5 o C and the average maximum temperature in July is higher than 30 o C. The low-temperature cracking is considered as the main control factor for the climate areas where yearly extreme low temperature is lower than -21.5 o C and the average maximum temperature in July is lower than 30 o C. For the rest of climate areas, both low-temperature cracking and high-temperature rutting of asphalt mixture are designed as the control factors.

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.
