Asphaltic Concrete Overlays of Rigid and Flexible Pavements
This study represents the development of a mechanistic approach to asphaltic concrete overlay thickness selection for overlays of flexible, rigid, and composite pavements. The procedure utilizes a deflection analysis to determine pavement rehabilitation needs. Design guides for selecting the overlay thicknesses are presented. Tolerable deflection-traffic load relationships and the deflection attenuation properties of asphaltic concrete have been developed, representing the subgrade support conditions and properties of materials used in Louisiana. All deflection measurements on asphaltic concrete have been corrected for the effect of temperature. Deflection measurements taken before and after overlay were also adjusted to minimize the effects of seasonal subgrade moisture variation.
