Structural Design
Pavement Structure
HMA pavements are flexible pavements. Flexible pavements are so named because the total pavement structure deflects, or flexes, under loading. A flexible pavement structure is typically composed of several layers of material. Each layer receives the loads from the...
Pavement Response
How a pavement responds to applied stresses is the combined result of loading, environment, subgrade and pavement material characteristics. This section presents the typical stresses and deformations experienced by an HMA pavement structure under load. Stress The...
Structural Design Methods
The goal of structural design is to determine the number, material composition and thickness of the different layers within a pavement structure required to accommodate a given loading regime. This includes the surface course as well as any underlying base or subbase...
Perpetual Pavements
Advancements in milling, recycling and HMA technology over the last few decades have created HMA pavements that perform better, longer and with lower life-cycle costs than was previously possible. Today’s HMA pavements can be designed to last in perpetuity. A...
