The Impact of Design, Construction and Maintenance Features on the Long-Term Performance of Pavements

After participating in this course, you will be able to:

• Understand key components and factors necessary for the cost-effective design of flexible and rigid pavements.
• Be able to identify design and construction features that may negatively impact the performance of pavements.
• Assist in developing specifications to ensure the performance of pavements.

Description

This webinar illustrates the impact of design, construction and maintenance features on the long-term performance of flexible and rigid pavements. The primary design, specification and construction factors contributing to pavements' long-term functional and structural performance, ranging from parking lots to municipal roadways, airports and major highways, are discussed.

Through a series of case studies, positive and negative features are presented to give the participant a good understanding of what we can do better to ensure the cost-effective use of transportation investments.

Who Should Attend

• Architects and engineers involved in the design, evaluation and management of pavements
• Roadway agencies
• Pavement maintenance staff
• Construction personnel
