Approach to Set Stresses Field of Flexible Pavements
Flexible pavements, as one of engineering subject, its stresses field is foundation and take play an important role to its mechanics analysis, life prediction, damage evaluation, and performance estimation. Simple expression of stresses filed in flexible pavement at special conditions (configurations of pavement, material properties, and traffic loading) is given in this research. The work is done by use of numerical analytical methods what 3D finite-element method and function fitting technology. The applicability of the proposed approach is verified using Boussinesq’s solution of semi-infinite elastic solid.
