Book Description
Seven flexible pavements ranging from interstate to state route are selected. Three different approaches are employed. The first two use the resilient modulus of the material to estimate its structural coefficient. In the first approach, cored specimens are obtained from each of the pavement sections and the resilient moduli of in-service 301 and 446/448 materials are determined in the laboratory. The second approach backcalculates layer elastic modulus from measured pavement deflection. The third approach determines the structural coefficient from the AASHTO flexible pavement performance equation based on traffic and serviceability history data.

Book Description
Structural Behavior of Asphalt Pavements provides engineers and researchers with a detailed guide to the structural behavioral dynamics of asphalt pavement including: pavement temperature distribution, mechanistic response of pavement structure under the application of heavy vehicles, distress mechanism of pavement, and pavement deterioration performance and dynamic equations. An authoritative guide for understanding the key mechanisms for creating longer lasting pavements, Structural Behavior of Asphalt Pavements describes the intrinsic consistency between macroscopic performance and microscopic response, structure and material, as well as global and local performances, and demonstrates the process of pavement analyses and designs, approaching science from empirical analyses. - Analyzes the external and internal factors influencing pavement temperature field, and provide a review of existing pavement temperature prediction models - Introduces a "Bridge Principle through which pavement performance and fatigue properties are consolidated - Defines the intrinsic consistency between macroscopic performance and microscopic response, structure and material, as well as global and local performance - Summaries the mechanistic response of pavement structure under the application of heavy vehicle, distress mechanism of pavement, pavement deterioration performance and dynamic equations, and life cycle analysis of pavement

Book Description
In this study, a rational overlay design method for flexible pavements in Arizona has been developed which includes roughness, fatigue and plastic deformation models. The method is incorporated in a microcomputer program which is also capable of analyzing the economics of other rehabilitation alternatives. During the development of the method, twenty in-service pavement sites were selected from Arizona highways covering various geographical and environmental regions, soil types, pavement conditions and traffic volumes. nondestructive tests (NDT) were performed on these sites using the Falling Weight Deflectometer at three stress levels as well as the Dynaflect. The pavement layers and subgrade moduli were backcalculated from NDT data using both static and dynamic analyses. The moduli of asphaltic layers were further adjusted for temperature. Statistical analysis was performed and the stress sensitivity was found to be small. Cone Penetration tests were further performed to verify the subgrade moduli. Asphalt concrete cores, base and subbase samples and undisturbed subgrade materials. In addition, base and subbase gradation as well as soil classification and Atterberg limits were obtained. The study expanded the data base for material properties in Arizona. This volume is the first in a three volume set. Volume II provides field testing procedure and workstation development and Volume III is a computer user guide.
