This paper summarizes the findings of a six-year study of moisture damage of asphalt mixtures, which was conducted at The University of Texas at Austin. The objectives of the study were to define the nature and severity of moisture damage in asphalt pavement mixtures, develop techniques to identify mixtures that are moisture susceptible, and develop recommendations to eliminate or minimize the problem. While this study has primarily focused on problems and mixtures in Texas, additional mixtures and experience from other areas in North America were considered. The study involved laboratory investigations, including the evaluation of mixtures subsequently used in construction, a field evaluation of methods of treating asphalt mixtures with hydrated lime, and an evaluation of actual pavement mixtures that exhibited moisture damage.

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.

The premier guide for understanding the causes and treatments for moisture damage of HMA (hot mix asphalt), this manual helps technicians learn test methods to evaluate damage potential, treatments to prevent moisture damage, and best practices to minimize moisture damage in HMA pavements.

An excellent overview of the field, covering in detail a wide range of different types of constituent materials, such as polymers, metals and metal oxides. It discusses their production and synthetic routes, as well as applications in several areas, including catalysis, drug delivery and environmental science. A must-have for scientists in academia and industry, as well as a valuable resource for both newcomers and more established researchers working in the field.
