Section 3: FPS 21 Design Parameters - Texas Department …

3.1 Introduction. The required analytical method of flexible pavement design is FPS 21. FPS 21 uses a systems approach centered upon deflection measurements from the falling weight deflectometer (FWD). These measurements are then used by the MODULUS computer program to estimate the material properties (modulus) of the pavement layers through a

Asphalt Pavement Construction | Asphalt Institute

The Asphalt Institute recommends a transverse slope of between 1.5 to 3.0% on all pavement surfaces, and an even steeper slope of 3 to 6% on shoulders. Maintaining a slope of at least 1.5% on parking lots will ensure proper surface drainage (no ponding or birdbaths) and minimize infiltration, hydroplaning and the detrimental effects of water.
