Abstract

Embodiments of the present invention are generally related to an emulsion tack coat applicator and methods of utilizing the same. More specifically, embodiments of the present invention relate to hand truck-type applicator for emulsion tack coat applications and methods of using the same. In one embodiment of the present invention, a tack coat applicator comprising a hand truck comprising a substantially frame having a handle section at a first end and a set of wheels separated by an axle at a second end, and a platform extending substantially perpendicular to the rigid proximate the wheels; and bucket having a voluminous storage portion for storing tack coat material, removeably positioned on the platform, the bucket comprising an output for dispensing the tack coat material.

Claims

1. A tack coat applicator comprising:

a hand truck comprising a substantially rigid frame having a handle section at a first end and a set of wheels separated by an axle at a second end, and a platform extending substantially perpendicular to the rigid frame proximate the wheels;

a bucket disposed against the hand truck frame, the bucket having a rear sidewall substantially parallel to the frame between the set of wheels and the handle section, the bucket having a voluminous storage portion for storing tack coat material, removeably positioned on the platform, the bucket comprising an output in the rear sidewall of the bucket for dispensing the tack coat material, the output comprising a valve and nozzle assembly extending from the rear sidewall of the bucket through a rear of the hand truck, the output positioned between an operator and the bucket; and

whereby applying a pulling force on the tack coat applicator allows the operator to be positioned ahead of the output to avoid stepping in or around applied tack coat material, reducing operator fatigue and tack coat smudge.

2. The tack coat applicator of claim 1, wherein the valve comprises one of a ball valve, a butterfly valve, globe valve, gate valve, diaphragm valve, a pneumatic valve, a solenoid valve, or combinations thereof.

3. The tack coat applicator of claim 1, wherein the nozzle outputs the tack coat at an application rate of between about 0.02 gallons/yd² to about 0.30 gallons/yd².

4. The tack coat applicator of claim 3, wherein the nozzle outputs the tack coat at an application rate of between about 0.03 gallons/yd² to about 0.20 gallons/yd².

5. The tack coat applicator of claim 1, wherein the hand truck further comprises a saddle portion having at least one support plate positioned parallel to the platform, the support plate having an aperture therethrough for supporting the bucket.

6. The tack coat applicator of claim 5, wherein the saddle portion comprises at least a plurality of support plates.

7. The tack coat applicator of claim 1, wherein the bucket further comprises a handle.

8. The tack coat applicator of claim 7, wherein the handle is removeably affixed to a cross bar of the hand truck via a spring link.

9. The tack coat applicator of claim 1, wherein the bucket further comprises a removable lid.

10. The tack coat applicator of claim 1, wherein the bucket further comprises a second port for access to the voluminous storage portion therein.

11. A tack coat applicator comprising:

a hand truck comprising a substantially rigid frame having a handle section at a first end and a set of wheels separated by an axle at a second end, a platform extending substantially perpendicular to the rigid frame proximate the wheels, and a saddle portion having at least one support plate positioned parallel to the platform, having an aperture therethrough for supporting a bucket;

the bucket disposed against the hand truck frame, the bucket having a rear sidewall substantially parallel to the frame between the set of wheels and the handle section, the bucket comprising a voluminous storage portion for storing tack coat material, removeably positioned on the platform, a handle, and an output in the rear sidewall of the bucket, the output comprising a valve and nozzle assembly extending from the rear sidewall of the bucket through a rear of the hand truck, the output positioned between an operator and the bucket; and

whereby applying a pulling force on the tack coat applicator allows the operator to be positioned ahead of the output to avoid stepping in or around applied tack coat material, reducing operator fatigue and tack coat smudge.

12. The tack coat applicator of claim 11, wherein the nozzle outputs the tack coat at an application rate of between about 0.02 gallons/yd² to about 0.30 gallons/yd².

13. The tack coat applicator of claim 12, wherein the nozzle outputs the tack coat at an application rate of between about 0.03 gallons/yd² to about 0.20 gallons/yd².

14. The tack coat applicator of claim 11, wherein the saddle portion comprises at least a plurality of support plates.

15. The tack coat applicator of claim 11, wherein the handle is removeably affixed to a cross bar of the hand truck via a spring link.

16. The tack coat applicator of claim 11, wherein the bucket further comprises a removable lid.

17. The tack coat applicator of claim 16, wherein the bucket further comprises a second port for access to the voluminous storage portion therein.

18. The tack coat applicator of claim 17, further comprising a pressurized control system for maintaining substantially constant pressure within the voluminous storage portion of the bucket via the second port.

19. An emulsion tack coat applicator comprising:

a hand truck comprising;

a substantially frame having a handle section at a first end and a set of wheels separated by an axle at a second end;

a platform extending substantially perpendicular to the rigid proximate the wheels; and

a saddle portion having a plurality of support plates positioned parallel to the platform, each support plate having an aperture therethrough for supporting a bucket disposed against the hand truck frame, the bucket having a rear sidewall substantially parallel to the frame between the set of wheels and the handle section, the bucket, and at least one support panel positioned between the plurality of support plates forming a sidewall; and

the bucket, removeably positioned on the platform, comprising;

a voluminous storage portion for storing tack coat material;

a rotatable handle, removeably affixed to a cross bar of the hand truck via a spring link; and

an output in the rear sidewall of the bucket, the output comprising a valve and nozzle assembly extending from the rear sidewall of the bucket through a rear of the hand truck, wherein the nozzle outputs the tack coat at an application rate of between about 0.02 gallons/yd² to about 0.30 gallons/yd², the output positioned between an operator and the bucket; and

whereby applying a pulling force on the tack coat applicator allows the operator to be positioned ahead of the output to avoid stepping in or around applied tack coat material, reducing operator fatigue and tack coat smudge.
