Structural Design of Asphalt Pavements: Principles and ...

Jul 21, 2015  An asphalt pavement is made up of multiple layers, namely subgrade, sub-base, base, surfacing and wearing course. While there are design considerations involved in a pavement from the geometric, functional and drainage aspects, the structural design indicates estimation of appropriate thicknesses of the pavement layers.

The above solution refers to the half-space case or to the full-depth asphalt pavement case. For the layered pavement, a FEM analysis is needed (a commercial software ADINA is used in this study). In the FEM analysis, a block of asphalt concrete of 5×5×3 in3 subjected to a 100 lb load distributed on a 0.5 inch strip is simulated.

Abstract. Pavement design has relied for a very long time on simplified mechanistic methods and experience. The need for long life maintenance structures, the use of new, costly, materials with enhanced characteristics, the need to spend the maintenance euro as effective as possible, the need to quantify risks etc, have given a boost to a renewed interest in the characterization and modeling ...
