The newly revised and updated Second Edition of Pavement Design and Materials offers a comprehensive treatment of pavement materials, structural analysis, design, evaluation, and economic analysis of asphalt and portland concrete pavements.
Written by two highly qualified engineering professors with a wealth of experience in the field, Pavement Design and Materials provides readers with: - State-of-the-art techniques for material characterization, including a linear viscoelasticity primer - Methods and software for the analysis of flexible and ridgid pavements including the AASHTOWare Pavement ME Design - State-of-the-art pavement evaluation techniques including moduli backcalculation methods - Pavement economic analysis techniques including the most up-to-date user cost relationships.
The book companion website provides: - Solved examples in each chapter and the electronic files associated with them - An instructor solutions manual for the problems provided at the end of each chapter - PowerPoint presentations by chapter to facilitate lecture delivery
Pavement Design and Materials is an essential up-to-date textbook on the subject for upper-level undergraduate and graduate level courses on pavement materials and pavement design. It is also a valuable reference for practicing professional engineers involved in the various aspects of roadway pavement material selection and structural design.
