Component Analysis - Asphalt Institute - Pavement …

The Asphalt Institute ’s component analysis design approach (termed “effective thickness” by the Asphalt Institute) uses relationships between subgrade strength, pavement structure, and traffic (Asphalt Institute, 1983). The existing structural integrity of the pavement is converted to an equivalent thickness of HMA, which is then compared to that required for a new design.

Emphasis has been placed on alternatives to combine sound pavement management principles, accurate distress identification, and a detailed structural analysis for an asphalt overlay design to carry the projected vehicular loading. This edition reflects changes in rehabilitation strategies that took root in the late 1980s and early 1990s.

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.

Structural Design of Asphalt Pavements: Principles and ...

Procedures to perform structural design of pavements are detailed in various design guidelines. Even though the recommendations may be different across the different guidelines, some of the underlying principles are similar. The present paper briefly reviews various pavement design guidelines on structural design of asphalt pavements with reference to the design principles employed.

The overlay design procedure, as outlined in the Asphalt Institute Manual, Asphalt Overlays for Highways and Street Rehabilitation, (5) can also be used for thickness design. The overlay thickness is calculated as the difference between the thickness required by a new pavement to the design traffic ESAL and the effective thickness of the existing pavement.
