Description

This webinar examines the basic design principles of flexible (asphalt-surfaced) and rigid (concrete-surfaced) pavements to give participants a good understanding of "what matters" to ensure the maximum pavement life possible. Constructing a pavement is less precise than factory manufacturing, where the input materials and processes are strictly controlled to produce the desired final product. While processes and procedures are in place for quality control and quality assurance, changes and variations in the materials, weather conditions, contractor operations, etc., can significantly impact the pavement's life. Case studies of "cause" and "effect" are presented in a sequence of construction commencing at the subgrade and working towards the pavement surface to illustrate the impact of poor quality construction and inspection on pavement performance. 

Frequently, construction inspectors are not fully aware of the consequences of poor construction practices and are reluctant to "get into an argument" with construction personnel. Pavements typically do not fail catastrophically, and construction defects may take years to manifest themselves in distress and deterioration. The cost to "repair" the defects may be much higher than the original cost of construction, and the repairs themselves may contribute to further pavement distress. By understanding and identifying poor practices and ways of improving them, we can contribute to a sustainable infrastructure system.
