DESIRED PHYSICAL PROPERTIES OF ASPHALT PAVING MIXTURES

Flexible pavements -- whether a highway or airport pavement -- are designed to minimize the amount of distress or deterioration during a specific period of time usually called the service life. Flexible highway pavements which are subjected to various types of axle loads and fluctuating environmental conditions should be designed adequately to achieve the envisioned performance. Surface deflections, vertical strains on the subgrade and tensile strains in the asphalt layers are the critical parameters to be controlled to maximize the service life of the flexible pavement. Each pavement structure displays different behavior and yields varying levels of deflections, vertical and tensile strains depending upon the pavement thickness, subgrade strength, quality of materials used in the pavement layers and traffic loads.
