Abstract(s)Predicting pavement evolution is a fundamental component in pavement maintenance and rehabilitation management work. However, it is very complex to carry out due to several drawbacks, namely a common use of inadequate quality control procedures or a lack of reproducibility of quality control data. This paper describes the main conclusions of a study on the influence of construction quality control data on pavement evolution. It was possible to develop a methodology for this purpose based on stiffness modulus evolution, which will also allow for the assessment of the pavement’s design. The study involved the establishment of a statistical analysis procedure in order to analyse construction quality variability data, and the use of deflection tests, stiffness modulus tests, back-analysis of FWD data and the development of a procedure to correct the effect of temperature within the pavement on stiffness modulus. Results analysis showed that control quality data variability has an important influence on pavements’ evolution prediction. It is expected that the integration of the proposed methodology on quality control plans will improve the data accuracy and all the decisions based on it.
