Resumen de Bearing capacity assessment of recycled asphalt pavements
Full-depth cold in place recycling technology was used for the rehabilitation of a heavily trafficked highway asphalt pavement. For the evaluation of the bearing capacity of the foamed asphalt treated recycled pavement, the NTUA Laboratory of Highway Engineering undertook research on the subject, including continuous monitoring of the pavement performance through detailed analysis. The trial field investigation was based primarily on non-destructive tests using the falling weight deflectometer (FWD) along several trial subsections of a rehabilitated pavement. According to the data analysis, the FWD was proven a useful tool for reliable assessment of the bearing capacity of recycled pavement. Deflection indicators give useful information about the structural condition of the recycled pavement, but more precise results are drawn with backanalysis and strain response analysis of the in-situ collected data. The distress in the body of the recycled layer is lower than expected, indicating adequate bearing capacity of the recycled pavement.
