Abstract
Systems and methods for cleaning asphalt contact surfaces are provided. One such system includes a means for determining a dilution ratio appropriate to a particular asphalt contact surface, a nozzle proximate to the asphalt contact surface, and a pump in fluid communication with the nozzle. The pump is configured to deliver to the nozzle a mixture of water and said cleaning compound with the appropriate dilution ratio. One such method includes the steps of: pumping a cleaning mixture with a dilution ratio appropriate to a particular asphalt contact surface; supplying said pumped cleaning mixture to at least one nozzle proximate to the asphalt contact surface; and spraying the asphalt contact surface through the nozzle with the pumped mixture.
