LTPP Data Analysis: Effectiveness of Maintenance and Rehabilitation Options

Various maintenance and rehabilitation options are employed by highway agencies to restore pavement condition and extend pavement life. For specific climate conditions and traffic levels, the performance of the restored pavement will depend on the type of maintenance or rehabilitation option, but also on the existing pavement condition when these measures are applied. However, these relationships are not well documented. Without this information, the selection of appropriate maintenance or rehabilitation options that will ensure long-term performance is a difficult task. Research is needed to identify the existing pavement conditions that influence the effectiveness of the different maintenance and rehabilitation options and to determine the relative performance of these options. The data available from the Long Term Pavement Performance (LTPP) studies are expected to provide such information.
