Asphalt release agent automated spray system

A method for applying a fluid to a vehicle comprising the steps of:

• (a) providing an automatic vehicle spraying system comprising a frame support;
• a boom having a proximal end and a distal end, wherein the proximal end of the boom is connected to the frame support;
• a spray apparatus positioned below the distal end of the boom;
• a hose array attached to the spray apparatus, wherein the hose array extends along the boom and down the frame support;
• an actuator attached to the frame support and operationally attached to the hose array;
• a vertical sensor positioned at or near the distal end of the boom and a horizontal sensor positioned at or near the frame support, wherein the sensors are able to produce an output signal when a vehicle passes underneath the spray apparatus;
• and a controller able to receive the output signals from the vertical and horizontal sensors, wherein the controller causes the actuator to raise and lower the spray apparatus from the boom;
• (b) detecting a vehicle in position underneath the spray apparatus;
• (c) measuring the distance between the vehicle and the vertical and horizontal sensors;
• (d) comparing the measured distances with preset values;
• (e) lowering the spray apparatus when said measured distances fall within said preset values;
• and
• (f) activating a pump in pumping relation with a fluid reservoir containing said fluid, wherein said fluid reservoir is in fluid communication with the spray apparatus and said fluid is pumped from the fluid reservoir to the spray apparatus.

A method for applying an asphalt release agent to a vehicle comprising the steps:

• (a) detecting a vehicle in position underneath a spray apparatus attached to a boom, wherein said spray apparatus comprises at least one spray nozzle;
• (b) measuring the distance between the vehicle and a vertical and horizontal sensor;
• (c) comparing the measured distances with preset values;
• (d) lowering the spray apparatus from the boom when said measured distances fall within said preset values;
• (e) activating a pump in pumping relation with a fluid reservoir containing asphalt release agent wherein said fluid reservoir is in fluid communication with said at least one spray nozzle, wherein said asphalt release agent is pumped from said fluid reservoir to said at least one spray nozzle;
• and
• (f) stopping said pump and raising the spray apparatus.
