Aasho Road Test Findings Applied to Flexible Pavements in Virginia
The method for design of flexible pavements presented is based on the AASHO Road Test model equation and a theoretical equation for pavement deflection, and is recommended for use in Virginia. The independent variables evaluated are (1) the thicknesses of the layers of the pavement, (2) strength equivalencies of the materials in each layer of the pavement, (3)subgrade support value including the soil resiliency and the environmental conditions affecting it, and (4) traffic. The dependent variable is the Dynaflect deflections measured during the spring seasons of 1967 and 1968. The thickness equivalencies of the materials used in the construction of flexible pavements in Virginia have been determined. A soil classification map of Virginia has been prepared from data obtained from 200 projects covering the entire state. This map shows five soil classifications based on resiliency, the AASHO soil classification, and the texture of the soils. It was found that no relationship exists between the data obtained with the dynaflect and pavement roughness data. A design method for Virginia in the form of a nomogram is proposed as a design and maintenance tool. Two additional methods for design are given. (Author)
