The project is carried out according to the following research steps:
- Gathering current experiences and theoretical considerations – elements used in all stages of the project,
- Analysis of measurement data collected from operating systems – aimed at identyfying the standard axle load spectrum for self-calibration purposes,
- Modeling of the road pavement-axle load sensor system – at both laboratory and real-life scales, using the finite element method,
- Laboratory-scale testing of the road pavement-axle load sensor system – to calculate mechanical parameters and material constants for the development of system models,
- Modeling of dynamic loads exerted by the vehicle wheel on the sensor,
- Full-scale testing of the road pavement-axle load sensor system – enabling the measurement of pavement smoothness and stiffness modulus curves for mineral-asphalt mixtures,
- Computer simulations using numerical and mathematical models,
- Evaluation of solutions through full-scale testing,
- Implementation – in the form of new methods for verifying measurement data and weighing accuracy in HS-WIM systems, as well as new self-calibration algorithms for the systems, accompanied by appropriate guidelines provided to road administration.
