A NOMOGRAPHIC DESIGN METHOD FOR ASPHALT STABILIZED PAVEMENT LAYERS

This paper presents a design method for selecting the necessary thickness of each layer in a pavement structure which would insure adequate resistance to a large number of applications of vehicle loads. The method is applicable to the design of cohesive pavement materials, i.e., those which have tensile strength, and is composed of a series of design charts or nomographs for a simulated three layer pavement structure. Linear elastic layered theory was used in the development of the design nomographs which relate the tensile stresses and strains in the bottom fibers of the upper two pavement layers and the vertical strain in the top of the subgrade layer to the moduli of elasticity and thicknesses of the various pavement layers. Procedures for proper application of the nomographs to the structural design of asphalt stabilized pavement layers are presented including a method of selection of design thicknesses. Characterization techniques are also provided for estimating limiting design criteria for each of the proposed materials in the three pavement layers. The design method presented in this paper involves a practical interpretation of layered theory and emphasizes the contribution of each individual layer to the behavior of the total pavement structure. The solutions obtained from the design nomographs can be used by agencies which have limited access to computer facilities. Therefore state, city and county traffic departments can utilize these nomographs for the design of facilities with expectancy of high truck traffic. /Author/
