Book Description
The focus of this project is on the evaluation of the sensitivity of HMA performance to aggregate properties measured using conventional and image analysis methods. Wavelet image analysis is used to measure texture. Image analysis methods based on the changes in the gradient on a particle boundary, and the difference between a particle radius in a certain direction and that of an equivalent ellipse are used to quantify angularity. Form is quantified by a method that evaluates the changes in particle radii with a fixed incremental change in the central angle. Researchers measured the performance of HMA mixes with different aggregates using the asphalt pavement analyzer (APA), Hamburg wheel tracking device (HW), and dynamic modulus test (DM).

Book Description
In recent years, with the rapid development of the world transportation industry, the proportion of asphalt pavement in road engineering is increasing. Therefore, while the demand for asphalt and asphalt mixture is increasing, the quality requirements for materials are also improving. In particular, new materials and new technologies are constantly emerging, and the application technology, theory, and technical specifications of asphalt materials have made great progress.

Book Description
This textbook lays out the state of the art for modeling of asphalt concrete as the major structural component of flexible pavements. The text adopts a pedagogy in which a scientific approach, based on materials science and continuum mechanics, predicts the performance of any configuration of flexible roadways subjected to cyclic loadings. The authors incorporate state-of the-art computational mechanics to predict the evolution of material properties, stresses and strains, and roadway deterioration. Designed specifically for both students and practitioners, the book presents fundamentally complex concepts in a clear and concise way that aids the roadway design community to assimilate the tools for designing sustainable roadways using both traditional and innovative technologies.
