Patent number: 11352755Abstract: A spraying system for a road construction machine includes an emulsion fluid delivery system including an emulsion fluid supply, an emulsion pump, at least one spray bar with one or more nozzles, and flow conduits arranged to convey emulsion through the emulsion fluid delivery system. The spraying system may include a cleaning fluid tank containing a cleaning fluid, where the cleaning fluid tank is fluidly coupled to the emulsion fluid delivery system during a cleaning process. The spraying system may also include a flow monitoring system configured to monitor the amount of cleaning fluid delivered from the cleaning fluid tank to the emulsion fluid delivery system, where the flow monitoring system is configured to provide an indication regarding the amount of cleaning fluid delivered to the emulsion fluid delivery system during the cleaning process.Type: GrantFiled: May 29, 2019Date of Patent: June 7, 2022Assignee: Caterpillar SARLInventors: Chad M. Thiesse, Andrea Fontana

Patent number: 10787773Abstract: A paving system may include a paving machine, including a paving material delivery assembly, including a hopper, a conveyor assembly, an auger, and a screed. The paving machine may also include an emulsion fluid delivery assembly including a plurality of spray bars, wherein each spray bar includes one or more nozzles. The paving system may also include a controller and a display interface. The controller may be configured to receive inputs from the display interface indicative of a mass and an area of emulsion fluid delivered from one active nozzle in order to calibrate the emulsion fluid delivery assembly.Type: GrantFiled: May 29, 2019Date of Patent: September 29, 2020Assignee: Caterpillar SARLInventors: Chad M. Thiesse, Andrea Fontana
