Terminal Asphalt Patching: An Innovative Approachby C. Davis Rudolf, III, Virginia Int Terminals, Inc, Norfolk, United States,
George Degaraff, Virginia Int Terminals, Inc, Norfolk, United States,
Abstract: Asphaltic concrete has dominated the terminal industry as the pavement of choice for years. It is readily available and economical to install but requires considerable maintenance expense. In an attempt to reduce this expense Virginia International Terminals sought a means to repair potholes quicker and cheaper. The result was the purchase of a 'ONE SHOT' patching machine which, combined with a dump truck loaded with aggregate, reduced the cost of patching by a factor of 3 while filling the holes 3 times faster. The finished patches, formed with a latex emulsion and aggregate, can be put in service immediately and are more durable than conventional methods.
