Abstract

The sustainability of pavement slabs was analyzed using finite element models with Abaqus and EverFE to establish both surface and deep stress zones and the delimitation of damage. The stress results of finite element models with these two tools were verified with the results of the Westergaard analytical model. It was found that, in the case of load located at the edge of the slab -where the main stress is higher- the EverFE model is better verified with the analytical model while, in the load cases located at the corner and interior the slab -where stresses are lower-, Abaqus model is closer to the results of the analytical model, concluding that both tools are powerful and reliable for the analysis of stresses in pavement slabs. This type of analysis with a sustainable focus leads not only to better decision making in the design, management and construction of pavement slabs, but also to better conservation alternatives for these structures.
