Session Title
Pavement Underdrain to Achieve Longer Life Pavement Structure
Track Title
Pavements
Event Description/Abstract
Drainage as the key to pavement performance has been suggested since the early design of modern pavement structures. In fact, the three parameters for pavement performance are drainage, drainage and drainage. Drainage is so important to the performance of pavement that many state DOTs mandate a pavement underdrain system for routes with medium to high truck traffic. In the current evolution of pavement underdrain design, the speed of water removal from the soil foundation is the key issue. In a recent field investigation, some pavement sections with an underdrain system are not immune to pavement structural deterioration. It was determined that proper construction of the underdrain system is the key to ensuring that water will not accumulate in the soil foundation. This presentation will explore the requirements, design, construction, and performance of the underdrain system.
