Abstract

A vehicle for transporting and dispensing materials required for filling and repairing cracks in roadways and highways and the like is disclosed. The vehicle comprises a tank for carrying asphalt mix or emulsion or the like liquid crack-filling material, a hose connected to the tank for moving the crack-filling material from the tank to a dispensing area adjacent the vehicle, a manually directable applicator wand connected to the hose for manually directing crack-filling material from the tank into cracks in the roadway, a hopper for carrying sand, rock chips, or other substantially dry structural material for covering the liquid crack-filler material and binding therewith to form a substantially firm roadway surface, a conveyor interconnected with the hopper for moving sand or other structural filler material therefrom to the dispensing area adjacent the vehicle, and controls for driving the vehicle positioned on the vehicle immediately adjacent the dispensing area such that the dispensing area is clearly viewable by an operator at the driving control position.

Claims

1. a vehicle for transporting and dispensing materials required for filling and repairing cracks in roadways and highways or similar, said vehicle comprising:

a. a storage tank for asphalt mix or emulsion or the like liquid crack-filling material;

b. hose means leading from said tank to a dispensing area adjacent said vehicle;

c. manually directable applicator wands connected to said hose for manually directing crack-filling material from said tank into cracks in the roadway;

d. a hopper for carrying sand, rock chips, or other substantially dry structural material for covering the liquid crack-filler material and binding therewith to form in the aggregate substantially firm roadway surface;

e. a said dispensing platform attached to said vehicle adjacent said dispensing area;

f. a conveyor interconnected with said hopper for moving sand or other structural filler material therefrom to said dispensing area adjacent said vehicle; and

g. controls for driving said vehicle positioned on said vehicle immediately adjacent said dispensing area such that said dispensing area is clearly viewable by an operator at said driving control position.

2. The vehicle for transporting and dispensing materials required for filing and repairing cracks in roadways and highways or similar as in claim 1, further comprising a pivotable boom connected to said vehicle for providing overhead support to said hose and applicator wand a distance ahead of said sanddispensing platform in the direction of motion of the vehicle so that a sand shoveler can apply sand to the filled cracks behind the crack-dispensing operator.

3. A vehicle for transporting and dispensing materials required for filling and repairing cracks in roadways and highways or similar as in claim 1, wherein

said sand shoveling platform is positioned for receiving sand or other materials from said conveyor at a height between 11/2 feet and 21/2 feet from the roadway surface in the dispensing area such that the sand shovelers need not stretch or stoop to reach the sand or material received by sand-shoveling platform while shoveling the sand on filled cracks.

4. The vehicle for transporting and dispensing materials required for filling and repairing cracks in roadways and highways or similar as in claim 1 and wherein the hopper is positioned on said vehicle separate from said dispensing area;

and said conveyor is a continuous belt conveyor extending from said hopper to said sand dispensing area.

5. The vehicle for transporting and dispensing materials required for filling and repairing cracks in roadways and highways or similar as in claim 1 where the sand hopper is separate from said dispensing area and said conveyor is an auger in a pipe having an inlet in said hopper and an outlet positioned at said dispensing area.
