Purpose and Background
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 that contribute to the long-term functional and structural performance of pavements ranging from parking lots to municipal roadways, airports and major highways are discussed. Through a series of case studies, this webinar presents positive and negative features to give the participant a good understanding of what we can do better to ensure the cost-effective use of transportation investments.
Primary Discussion Topics
- Design impact
- Construction and maintenance features
- Design, specification, and construction factors that contribute to key pavement performances
Learning Outcomes
Upon completion of this course, you will be able to:
- Recognize and use current common pavement design procedures
- Determine common design and construction features important to the performance of both asphalt and concrete pavements
- Design and recognize specification and construction activities that can improve the performance of pavements
- Communicate and promote good road design and construction practices
Webinar Benefits
- 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
- Understand the consequences of poor design, construction, and maintenance practices
- Look for and understand the impact of design and construction decisions on the long-term performance of pavements
- Assist in developing specifications to ensure the performance of pavements
- Identify methods to improve the sustainability and longevity of pavements
