Abstract
Flexible pavements are built from the soil up, and the quality and characteristics of each layer have a significant impact on performance. Soft soils and thin base layers can require thicker asphalt. Properly preparing and constructing asphalt bases can be a cost-effective way to achieve a perpetual pavement. In this session we will explore the impact of subgrade and base layers and how you can optimize pavement design for maximum performance.
