Book Description
Moisture induced damage in asphalt concrete pavements, better known as stripping, is one of primary causes of distresses in the asphalt pavement layers. AASHTO T283 has historically been used to detect moisture damage potential of asphalt mixes. This method is established for the Marshall mix design process. However, the current hot mix asphalt design calls for the use of Superpave mix design procedure using the Superpave Gyratory Compactor (SGC). The differences in the mix design methods will most likely introduce significant differences in stripping test results. Therefore, to improve the AASHTO T283 test procedure and to develop the new criterion for the Superpave HMA specimens, this project was conducted to evaluate the applicability of AASHTO T283 to the Superpave mixes. A structured laboratory test program was conducted in this research to study the effects of the various factors on the HMA specimen's susceptibility to moisture damage. A complete factorial experimental program for two aggregate sources with virgin asphalt binder was conducted together with a partial factorial experimental program for the other two aggregate sources with polymer modified asphalt binders. In the data analysis, the effects of different factors on dry tensile strength, freeze-thaw conditioned tensile strength, and tensile strength ratio (TSR) were investigated in this report. The effects of all the factors investigated in this research are summarized in this report. The recommendations for the proposed stripping test procedure for Superpave HMA are given at the end of the report.

Book Description
This synthesis will be of interest to pavement designers, construction engineers, maintenance engineers, and others interested in avoiding or limiting moisture damage in asphalt concrete. Information is provided on physical and chemical explanations for moisture damage in asphalt concrete, along with a discussion of current practices and test methods for determining or reducing the susceptibility of various asphalt concrete components and mixtures to such damage. Moisture damage in asphalt concrete is a nationwide problem which often necessitates premature replacement of highway pavement surfaces. This report of the Transportation Research Board describes the underlying physical and chemical phenomena responsible for such damage. Current test methods used to determine the susceptibility of asphalt concretes, or their constituents, to moisture damage are described and evaluated. Additionally, current practices for minimizing the potential for moisture damage are examined.

Book Description
This volume highlights the latest advances, innovations, and applications in the field of asphalt pavement technology, as presented by leading international researchers and engineers at the 5th International Symposium on Asphalt Pavements & Environment (ISAP 2019 APE Symposium), held in Padua, Italy on September 11-13, 2019. It covers a diverse range of topics concerning materials and technologies for asphalt pavements, designed for sustainability and environmental compatibility: sustainable pavement materials, marginal materials for asphalt pavements, pavement structures, testing methods and performance, maintenance and management methods, urban heat island mitigation, energy harvesting, and Life Cycle Assessment. The contributions, which were selected by means of a rigorous international peer-review process, present a wealth of exciting ideas that will open novel research directions and foster multidisciplinary collaboration among different specialists.

Book Description
The final product of the Strategic Highway Research Program (SHRP) Asphalt Research Program is the SUPERPAVE (registered trademark) mix design system for new construction and overlays. This system employs a series of new performance-based specifications, test methods, and practices for material selection, accelerated performance testing, and mix design. This report documents these new specifications and procedures in a format suitable for eventual American Association of State Highway and Transportation Officials (AASHTO) standardization.
