# Pavement Mechanics

## Overall Course Objectives

This course covers advanced analysis, design, and construction topics related to both concrete and asphalt pavements. Its main objective is to elevate and enrich the knowledge level of the students in order that they could understand the basic assumptions and limitations underlying existing state-of-the-practice methods, and also that they would be able to appreciate and critically evaluate new ideas.

Learning Objectives

• Better understand how pavements behave under service conditions
• Identify construction and design parameters that affect performance
• Compute mechanical responses by means of classical plate theory
• Compute mechanical responses by means of layered elasticity theory
• Identify common concrete pavement distress types
• Perform inverse analysis of pavement layer properties
• Employ linear viscoelastic theory for material characterization
• Utilize linear viscoelastic theory for structural modeling
