Asphalt Pavement Alliance webinar: Designing a Perpetual Pavement
August 25, 2021 @ 11:00 am - 12:30 pm| Free
Pavement engineers have been producing long-lasting asphalt pavements since the 1930s. Research has shown that well-constructed and adequately designed flexible pavements can perform well for extended periods of time. Many of these pavements were the products of full-depth or deep strength asphalt pavement designs, and both design philosophies have been shown to provide adequate strength over extended life cycles. This is possible because both types of design rely on the construction of a sound base as a working platform and to spread traffic loads in addition to a thick asphalt structure designed to reduce the tensile strains at the bottom of the asphalt as well as the compressive strains at the top of the subgrade. This webinar will discuss material selection and mixture design to optimize Perpetual Pavement performance, discuss current Perpetual design practices, and present best practices for construction of high quality, high performance pavements.
By the end of this presentation attendees will be able to:
1. List the chief advantages of Perpetual Pavements
2. Describe the functions of the various material layers in Perpetual Pavements
3. Discuss the principle design features of Perpetual Pavements
