Overview

Introduction

• Focus of concrete pavement design:

SLAB THICKNESS

• Does slab thickness solve all concrete

pavement performance problems?

Comprehensive Concrete Pavement Design

• More than just slab thickness

• Direct consideration of other design

elements, e.g.,

– Joint spacing

– Load transfer

– Shoulder design

• Design pavement as a system

Overall Course Objectives

• Recognize effect of design features on

performance

• Select appropriate design features

• Identify construction practices critical to

performance

Focus is on jointed plain

concrete pavements
