    Description

    Open pavements allowing water to drain down into the pavement have many advantages, with respect to noise, safety and the environment. Letting water into the pavement, however, is against highway engineering practice. The project has followed an instrumented pavement, with open asphalt and granular material, since 1991, and compared it to two more traditional pavements.
    The structural condition of the three test sections has been measured using the Falling Weight Deflectometer and through measurement of stresses and strains under heavy wheel loads. Measurements have been done at different times of the year to study the seasonal variations. Measured stresses and strains have also been compared to theoretical values, using different mathematical models. A new test series was carried out in the autumn of 1998,
