Distribution of stresses and strains in roads

ByBernardo Caicedo

From the age of the Roman empire to the present, construction of road structures has consisted of juxtaposing several layers of materials consisting of particles of different sizes and shapes with bonded or unbonded contacts. The fundamental principle behind mechanistic study of road structures is analysis of stresses and strains affecting the performance of each material. Despite huge advances in modeling materials based on the behavior of each grain and contact, continuum mechanics remains the main tool for designing road structures.
