Book Description
Moisture is a major source of degradation of hot mix asphalt (HMA) used in highway pavements. Moisture damage occurs when there is a loss of bond either at the asphalt-aggregate interface or within the asphalt mastic. The presence of moisture may strip asphalt binder from the aggregate (adhesive failure) and/or weaken the asphalt mastic (cohesive failure) resulting in pavement cracking and deformation. Bond strength is determined via a direct tensile test utilizing the Pneumatic Adhesion Tensile Testing Instrument (PATTI). The usefulness of the direct tensile test is determined for asphalt binders and mastics and the influence of moisture on tensile strength of asphalt binders and mastics and between asphalt and aggregate pairs is evaluated. The results of the experiments verify that moisture degrades the bond strength of asphalt binders, mastics, and between asphalt and aggregate. Results from the direct tensile test experiments are then linked to moisture diffusion simulations and bond strength degradation as a function of the amount of moisture at the asphalt-aggregate interface is established. Based on this relationship, the amount of damage that occurs over time in regards to the amount of moisture at the interface is quantified. Finally, limit-state based reliability analysis concepts are introduced to formulate a performance criterion for moisture-induced damage of asphalt-aggregate systems. The moisture-induced damage parameter is an integral part of a larger framework developed for predicting moisture-induced damage in asphalt mixtures.

Book Description
This book gathers the proceedings of an international conference held at Empa (Swiss Federal Laboratories for materials Science and Technology) in Dübendorf, Switzerland, in July 2020. The conference series was established by the International Society of Maintenance and Rehabilitation of Transport Infrastructure (iSMARTi) for promoting and discussing state-of-the-art design, maintenance, rehabilitation and management of pavements. The inaugural conference was held at Mackenzie Presbyterian University in Sao Paulo, Brazil, in 2000. The series has steadily grown over the past 20 years, with installments hosted in various countries all over the world. The respective contributions share the latest insights from research and practice in the maintenance and rehabilitation of pavements, and discuss advanced materials, technologies and solutions for achieving an even more sustainable and environmentally friendly infrastructure.

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.
