Structural evaluation of flexible pavements using non-destructive tests ; Caracterização Estrutural de Pavimentos Flexíveis através de Métodos de Auscultação Não Destrutivos
Tese de doutoramento em Engenharia Civil apresentada à Faculdade de Ciências e Tecnologia da Universidade de Coimbra ; The aim of this work is to contribute to the improvement of the methodologies used in structural pavement evaluation, concerning in particular the backcalculation of layer moduli based on Falling Weight Deflectometer (FWD) together with Ground Penetrating Radar (GPR) test results. The main aspects that are dealt with are the application of GPR to pavement evaluation, the use of FWD data together with layer thickness data obtained from GPR and the improvement of the efficiency of the backcalculation of pavement layer moduli using Artificial Neural Networks (ANN). The advantages in using the GPR equipment, as well as the difficulties that occur during testing and data interpretation are addressed. Procedures to overcome some of the problems associated with this technology and to improve the reliability of GPR use are also recommended. A methodology for structural pavement evaluation using artificial neural networks, based on both FWD and GPR test results is presented. The sensitivity of the proposed method to variations in pavement thickness or to variations in deflections is also addressed. An application of the proposed method to a runway pavement evaluation is presented. The analysis of the results showed the suitability and advantages of the proposed methodology for structural pavement evaluation. From the experience gathered some recommendations for use of ANN in pavement structural evaluation were drawn, in view of obtaining reliable results. ; O objectivo do presente trabalho é o de contribuir para o aperfeiçoamento das técnicas de ensaio e metodologias de análise para a caracterização estrutural de pavimentos, em particular no que se refere à interpretação de resultados de ensaios de carga com deflectómetro de impacto (FWD) conjuntamente com os do radar (GPR). Os principais aspectos abordados são a aplicação do equipamento radar para pavimentos, a utilização resultados obtidos com o ...
