Overview
Today, asphalt and concrete receive equal consideration by engineers. Improvements in pavement technology have largely eliminated the ruts that once plagued asphalt and cracks that spoiled concrete. Choosing a material is a matter of economics that considers life span, maintenance requirements, and road closure time.
Learn the pros and cons of choosing each material; design considerations of each; cost factors, including an example of a life cycle cost analysis; construction techniques and limitations; and maintenance and troubleshooting each material.
Learning Objectives:
• You will be able to review what a designer needs to know about concrete and asphalt.
• You will be able to discuss mixtures and production.
• You will be able to describe general design principles.
• You will be able to explain placement options and what not-to-do.
