1. O uso de redes neurais artificiais como ferramenta para auxiliar na determinação da vida útil de pavimentos flexíveis / Using artificial neural networks as a tool to assist in the evaluation of the remaining life of flexible pavements
Este trabalho apresenta um procedimento para auxiliar na determinação da vida útil de pavimentos flexíveis através da determinação de tensões e deformações causadas pela solicitação de um eixo padrão na estrutura de pavimentos flexíveis utilizando Redes Neurais Artificiais. Para treinamento e validação das redes foram utilizadas bacias de def

2. Um procedimento de retroanálise para pavimentos flexíveis baseado na teoria do ponto inerte e em modelagem matemática / A backcalculation procedure for flexible pavements based on inertial point theory and in mathematical modeling
A backcalculation procedure for flexible pavements is introduced based on inertial point theory for subgrade backcalculation readapted to theoretical deflection basins obtained with the load to Benkelman beam test. Beside subgrade backcalculation, it was developed a factorial mathematical model to obtain equivalent resilient modulus from the layers presents

3. Comportamento mecânico de agregado reciclado de resíduo sólido da construção civil em camadas de base e sub-base de pavimentos. / Mechanical behavior of recycled aggregate of construction and demolition waste in base and sub base layers of pavements.
Construction and demolition waste (CDW) is generated in significant amounts in medium and large size cities in Brazil and are usually disposed of illegally. For the thousands of kilometers of unpaved urban roads, the recycled aggregate of CDW is an alternative to conventional paving materials. This dissertation analyses the mechanical behavior of the recycle

4. Estudo de gradientes térmicos e deformações em "whitetopping" ultradelgado. / Thermal gradients and deformations in ultra-thin witetopping.
In this work, several factors affecting behavior and performance of ultra-thin whitetopping were evaluated taking advantage of a full scale experimental pavement, restored by applying such technique. Temperatures and thermal gradients in concrete thin slabs were evaluated by almost one year, comprising al the seasons. Load tests were carried out to allow str
