• Abstract:
  Research has shown that pavement subdrainage systems can increase the life of pavements by removing water that is detrimental to the pavement structure. The Mississippi Department of Transportation (MDOT) began including pavement subdrainage systems in the construction of major highways in the mid to late 1990's. The objectives of this study were to evaluate the performance of current MDOT subdrainage systems and to evaluate maintenance procedures and inspection schedules for existing edge drains and outlets. Research findings show the subsurface drainage systems instrumented in this study to be functioning efficiently. Research findings also indicate that no statewide inspection or maintenance schedules for pavement subdrainage systems are currently being followed by MDOT maintenance personnel.
