Pre-mixed permanent asphalt dispensing system

Abstract

Presented herein is a system for dispensing media within a trench. The system includes a carriage having a chassis supported on one or more wheels, and a hopper supported on the carriage. The hopper is configured to receive media through an opening and output the media through an outlet. The system also includes a churning device at an inner portion of the hopper configured to agitate the media within the hopper. The media exits the hopper into a chute that is configured to deposit the media within the trench. The system can also include at least one liquid dispenser configured to dispense the liquid on the media after the media has been deposited in the trench. In certain embodiments, the system can include at least one tamp configured to compress the media into the trench after deposition of the media and the liquid.

What is claimed is: 
     
         1 . A dispensing system configured to dispense media within a trench, the system comprising:
 a carriage having a chassis supported on one or more wheels;   a media hopper supported on the carriage, the media hopper having a top end and an outlet provided at a bottom end, and being configured to receive media through an opening at the top end and output the media through the outlet;   a churning device attached to an inner portion of the media hopper, wherein the churning device is configured to agitate the media within the hopper;   a chute in communication with the outlet of the media hopper and extending from the bottom end of the media hopper, wherein the chute is configured to deposit the media within the trench; and   at least one liquid dispenser in fluid communication with a reservoir configured to store a liquid, the at least one dispenser being supported by the carriage and in line with the chute, and wherein the at least one liquid dispenser is configured to dispense the liquid on the media after the media has been deposited in the trench.   
     
     
         2 . The dispensing system of  claim 1 , further comprising:
 at least one tamp connected to the carriage and positioned behind the chute, wherein the at least one tamp is configured to compress the media into the trench after deposition of the media and the liquid into the trench.   
     
     
         3 . The dispensing system of  claim 2 , wherein the at least one tamp comprises at least one roller in line with the chute and configured to roll over and compress the media into the trench. 
     
     
         4 . The dispensing system of  claim 1 , wherein the churning device comprises a rotor-type agitator configured to rotate about an axis oriented laterally across at least portion of a width of the hopper. 
     
     
         5 . The dispensing system of  claim 4 , wherein the churning device comprises a three-pronged agitator. 
     
     
         6 . The dispensing system of  claim 4 , wherein the churning device is driven by a motor configured to control to the rotational speed of the rotor-type agitator. 
     
     
         7 . The dispensing system of  claim 1 , wherein the churning device is mechanically driven by the rotation of the one or more wheels. 
     
     
         8 . The dispensing system of  claim 1 , wherein the churning device is positioned at the bottom end of the media hopper above the outlet. 
     
     
         9 . The dispensing system of  claim 1 , wherein the chute is configured to selectively articulate laterally such that the angle of the chute relative to the ground is altered. 
     
     
         10 . The dispensing system of  claim 1 , wherein the carriage comprises a handle and a handle control attached to the handle, the handle control being configured to control the flow of the media out of the chute. 
     
     
         11 . The dispensing system of  claim 1 , wherein the handle control is further configured to control flow of liquid from the at least one liquid dispenser via a flow-regulating valve. 
     
     
         12 . The dispensing system of  claim 1 , wherein the carriage comprises a handle and a handle brake attached to the handle, wherein the handle brake is configured to assist with the braking of the one or more wheels. 
     
     
         13 . The dispensing system of  claim 1 , further comprising:
 a ride height adjustment mechanism configured to adjust the height of the chute relative to the trench.   
     
     
         14 . The dispensing system of  claim 1 , wherein the media comprised water-activated cold patch asphalt. 
     
     
         15 . The dispensing system of  claim 1 , wherein the reservoir is remote from the carriage and connected dispenser via a hose. 
     
     
         16 . The dispensing system of  claim 1 , wherein the reservoir is supported by the carriage. 
     
     
         17 . The dispensing system of  claim 1 , wherein the at least one liquid dispenser comprises a posterior liquid dispenser. 
     
     
         18 . The dispensing system of  claim 17 , wherein the at least one liquid dispenser further comprises an anterior liquid dispenser. 
     
     
         19 . The dispensing system of  claim 1 , wherein the at least one liquid dispenser comprises a flow-regulating valve configured to regulate the flow of the liquid from the reservoir and flow of the water dispensed. 
     
     
         20 . The dispensing system of  claim 1 , wherein the at least one liquid dispenser is adjustable in 360 degrees.
