Pavement Repair Automationby Leland D. Smithson, Iowa Dep of Transportation, United States,
Abstract: Faced with aging and decaying road systems, continual downsizing of government staffs and increasing budget shortfalls, roadway maintenance needs some help. That help is on the way. It's coming in the form of improved materials and automated pavement repair equipment, both are end products of the Strategic Highway Research Program (SHRP) research. SHRP has been a concerted research effort to produce major innovations for increasing the productivity and safety of the maintenance of our nation's roads and streets. SHRP started maintenance equipment research by conducting a survey of existing equipment of selected surface repairs. These repairs included spall repair, joint resealing, and crack sealing in concrete pavements and pothole repair and crack sealing in asphalt pavements. The H-105 study recommended equipment development in three separate areas: automated equipment for filling and sealing transverse cracks and joints in asphalt and concrete pavements; and automated equipment for filling and sealing lingitudinal cracks and joints in asphalt and concrete pavements.
