Perpetual Pavements with Dr. Charles Gurganus, TTI
A Perpetual Pavement is a long-lasting, thick hot mix asphalt (HMA) pavement structure with an intended service life over 50 years without major structural rehabilitation. Although a Perpetual Pavement requires surface maintenance over its lifespan, the goal is to construct a pavement strong enough to resist structural distress and durable enough to withstand traffic and environmental damage. In this webinar, Dr. Charles Gurganus of the Texas A&M Transportation Institute will share the results of a study conducted on several existing structures; the results of which indicate excellent long-term performance is not only possible but is occurring. Existing sections show little to no structural distress with surfaces lasting upwards of 12 years before their first maintenance.
