Non-linear analysis; fatigue and permanent deformation; backcalculation of layer moduli; mechanistic empirical design methods; theories of pavement behavior; application of theory to the analysis and design of airport and highway pavement systems including rehabilitation design and computer applications; development of improved design and rehabilitation practices and procedures.

Prerequisite: CE 574.

Textbooks:. Yoder and Witczak, Principles of Pavement Design.

Reference: Library and Web.

Goals:

This course was designed for graduate students with background in pavement design, it is intended to advance them to new pavement design concepts and failure theories; structural sub-systems and rational procedures for design; probabilistic distress models using mechanistic parameters; computer simulation and field verification; performance prediction; optimal design strategy.

Prerequisites by Topic:

1. Asphalt concrete design and evaluation.

2. Basic methods of pavement design.

3. Basic understanding of statistical concepts.

Topics:

1. Initial considerations in the pavement design process: general considerations; roadbed soils; base and subbase materials; paving materials; drainage design; measures of pavement performance; vehicle, traffic and environmental considerations; variability and reliability in pavement design (8 classes)

2. Modeling of pavement behavior. Empirical and Mechanistic pavement models. Rutting, Fatigue and thermal cracking , and pavement roughness models. (7 classes)

3. Flexible pavement design: basic principles, AASHTO 2002 and other design methods including pavement shoulder (8 classes)

4. Rigid pavement design: basic principles; AASHTO 2002 and other methods including shoulder and composite pavements (8 classes)

5. Overlay design: flexible, rigid, composite and combinations (6 classes)

6. Pavement response analysis (including performance). Layered systems, linear , nonlinear, viscoelastic and combination analysis. (8 classes)

Computer Usage: All the homeworks require the use of PC software such as Mechpave, ELSYM5, VESYS, WESDEF, PCA, Deflect, Predict, Temperd, etc.
