Pavement Analysis and Design
Yang H. Huang
2ndPublisher: Prentice HallFormat: Hardcover
Focusing on mechanistic-empirical design procedures, this volume presents a comprehensive exploration of the structural analysis and design of highway pavements. Although the current Pavement Design Guide adopted by the American Association of State Highway and Transportation Officials (AASHTO) is mainly empirical, a new guide based on mechanistic-empirical procedures will be published and implemented in the very near future. This book will provide the fundamental background to a full understanding of these sophisticated procedures. The accompanying CD contains a Windows software called KENPAVE, which can be run on any personal computer with Windows 95 or higher. In addition to several input and graphics programs, KENPAVE consists of two well-known computer programs for pavement analysis and design: *The KENLAYER program for flexible pavements can be applied to a multilayered system under stationary or moving multiple wheel loads with each layer being linear elastic, nonlinear elastic, or viscoelastic.*The KENSLABS program for rigid pavements can be applied to multiple slabs fully or partially supported on a liquid, solid, or layered foundation with moment or shear transfer across joints. Both programs can perform damage analysis by dividing a year into a number of periods, each subjected to different combinations of singleand multiple-axle loads. Structural and geotechnical engineers can also benefit from this book by applying KENPAVE to the design of raft foundations. In addition to vertical loads, the foundation slab can be subjected to moments in two directions, such as those imposed by retaining walls, and the contours of positive and negative moments can be plotted. This information will be useful to determine the length and amount of reinforcements required.
