Anti-icing spray system
First Claim
1. A method of applying an anti-icing solution to a roadway comprising:
- providing a plurality of spaced apart spray nozzles defining a system length, wherein said plurality of spray nozzles are coupled to a plurality of spray valves;
supplying a pressurized anti-icing solution to each of said plurality of spray valves from a source of said anti-icing solution positioned upstream of said plurality of said spray valves; and
opening said plurality of spray valves for a plurality of predetermined time periods, wherein said predetermined time periods of at least some of said plurality of spray valves are greater than said predetermined time periods of at least some other of said plurality of spray valves.

Abstract
A method of applying an anti-icing solution to a roadway includes providing a plurality of spaced apart spray nozzles defining a system length. The plurality of spray nozzles are coupled to a plurality of spray valves. The method further includes supplying a pressurized anti-icing solution to each of the plurality of spray valves from a source of the anti-icing solution positioned upstream of the plurality of said spray valves. The method also includes opening the plurality of spray valves for a plurality of predetermined time periods, wherein the predetermined time periods of at least some of the plurality of spray valves are greater than the predetermined time periods of at least some other of the plurality of spray valves positioned upstream therefrom. In another aspect, an anti-icing assembly includes an anti-icing solution source, a valve in fluid communication with the anti-icing solution source, a nozzle connected to the valve, and a pressure detecting device coupled between the nozzle and the valve.
