Abstract

The paper presents a continuation of research on the effectiveness of weekend street repairs in Warsaw, building upon the results presented in the previous paper entitled: “The effectiveness of weekend road rehabilitations in Warsaw on the basis of deflection basin indices”. The aim of the current study was to analyse the durability of the applied design solutions based on measurements taken at three key stages: in 2016, before the repair; in 2019, three years after the repair; and in 2022, six years after the repair. Diagnostic tests were conducted, and deflection bowl parameters as well as changes in stiffness parameters (E1, E2, E3) of the pavement structure on selected street sections were analysed. The results revealed significant changes over time, enabling evaluation of the long-term effectiveness of the repair technology. Further observations are planned to develop predictive models and draw conclusions regarding the durability of the pavement in the coming years of operation.
