2016-4-10 Long Life Asphalt Pavement (LLAP) is a relatively new methodology that has formed from historical theories regarding limiting strain criterions in the base layer of deep lift asphalt pavements. The theory of such Long Life Asphalt Pavement (LLAP) ‘perpetual’ pavements is based on the concept of a Fatigue Endurance Limit (FEL) which ...

HOW LONG WILL AN ASPHALT PAVEMENT LAST? It depends on many things, namely: type of subgrade, rainfall, frost penetration, temperature differences, terrain, type and quantity of traffic, pavement design, materials, specifications, and construction. ... Again it is reasonable to expect 20 years service life of this pavement providing the criteria ...

2010-9-28 Perpetual Pavement is a three-layer pavement design, which should provide pavement life spans of up to five decades, with follow-up asphalt overlays as a sacrificial friction course to continue smoothness. Perpetual Pavements use multiple layers of engineered, durable asphalt to produce a safe, smooth, long-lasting road, APA says.

Construction quality is crucial to the long-term pavement performance. Construction factors such as surface preparation, placement, joint construction and compaction/consolidation have an overwhelming effect on pavement performance, which cannot be ignored or compensated for in mix or structural design. Other construction considerations such as plant operations, mix transport and quality ...
