PATCH MASTER METHOD


PATCH MASTER


SPECIFICATIONS FOR ASPHALT PAVEMENT POTHOLE REPAIR

1. Clear the pothole of all foreign and loose material.

2. Lower the Patch Master heating unit parallel with the pavement repair. Heat the pavement until the asphalt surrounding the hole is soft enough to scarify and taper.

3. Add a rejuvenator (Pavement Savers, Inc. 540T) to the existing asphalt at the rate of 1/10 gallon per square yard before the new asphalt is placed.

4. Place the new asphalt material by hydraulically auguring it from the Patch Master’s heated storage compartment, molding it to the existing asphalt.

5. Compact with an approved compactor or roller.

*NOTE: A. In freezing temperatures if the hole is filled with ice, lower the Patch Master heating unit over the hole, keeping it at about a 30 degree angle. This will create a draft and allow the vapors to escape, loosen the ice faster, and remove the chunk.

B. After the ice is loosened, broom most of the water out and remove the balance with a backpack blower or an air compressor, and then follow steps 1 thru 5.

SPECIFICATIONS FOR REPAIRING AN ALLIGATED AREA IN ASPHALT PAVEMENT OVER A STABLE BASE

1. Clear the area of all loose and foreign material.

2. Lower the Patch Master heating unit parallel with the pavement and heat until the asphalt is loose enough to scarify.

3. Apply a rejuvenator (Pavement Savers, Inc. 540T) to the scarified area at the rate of 1.03 gallon per square yard.

4. Add the new asphalt that is needed.

5. Compact with an approved compactor or roller.

NOTE: Depending on the size of the repair, sometimes it is recommended to reheat the repair after the rejuvenator and new asphalt has been placed.

This can be accomplished by lowering the Patch Master heating unit over the repair at about a 30 degree angle using short on and off cycles of the heating wall to prevent the combustion of the volatiles.

SPECIFICATIONS FOR REPAIRING A UTILITY CUT IN ASPAHLT AND

ASPHALT OVER CONCRETE ROADS USING CONVENTIONAL BACKFILL


1. Backfill the opening with an acceptable material compacted to 95 % in six inch layers, bringing it to the bottom of the pavement or a minimum of four inches, whichever is greater.

2. Clear all loose and foreign material off the vertical edges of the pavement, apply a bond coat on the asphalt portion before placing the asphalt.

3. Place the asphalt (hot or cold mix). If the pavement is more than four inches thick the asphalt should be installed in lifts no more than four inches at a time.

4. At this time the repair shall be left to settle (30-90 days).

5. After the settling period the repair may be completed by the Patch Master Method.

a. Clear the repair of all loose and foreign material.

b. Lower the Patch Master heating unit parallel with the repair and heat the existing asphalt repair and three inches beyond the edges.

c. Scarify the softened asphalt and remove if necessary to a minimum depth of 1 1/2 inches.

*d. Apply a rejuvenator (Pavement Savers, Inc. 540T) to the remaining asphalt at the rate of .03 gallon per square yard.

e. Place the new asphalt material by hydraulically auguring it from the Patch Master’s heated storage compartment, molding it to the existing asphalt.

f. Compact with an approved compactor or roller.

*NOTE: If cold mix asphalt was used for the base material, after the material has been removed to a depth of one and a half inches, reheat the existing asphalt burning off the cutback a thickness of at least one inch. Do not apply the rejuvenator.

SPECIFICATIONS FOR REPAIRING A UTILITY CUT IN ASPHALT AND

ASPHALT OVER CONCRETE ROADS USING SHRINKLESS BACKFILL



1. Backfill. All trenches, holes, and pits shall be filled with Thermal Power Shrinkless Fill, or equal brought up to 3” from, the top of the pavement. Restoration shall be such that it shall provide a condition equal to or better than the original condition of the soil.

2. After the backfill has been installed, the edges of the existing pavement shall be protected by the heat that is required to bake the Shrinkless Fill by applying about 1” of Shrinkless Fill on the top wider than the size of the Patch Master heating panel that is being used.

3. Bake the Shrinkless Fill until the top 8” are dry (in most cases about 10 minutes).

4. After the top 8” of the Shrinkless Fill have been baked, sweep the Shrinkless Fill that was placed on the asphalt surface around the cut into the cut.

5. The asphalt surface surrounding the cut shall be heated enough to scarify a minimum of 3” beyond the edge (just inside the size of the heating panel being used).

6. Apply a rejuvenation agent (Pavement Savers, Inc. 540T or equal) on the scarified asphalt at the rate of .03 gallons per square yard.

7. Fill the cut with asphalt, compact it and the surrounding area of the cut that was scarified, which will weld the new asphalt with the surrounding asphalt.

8. If the street must be opened to traffic, place a little coating of sand over the repair.

SPECIFICATIONS FOR FILLING A LOW AREA IN ASPHALT PAVEMENT

1. Clear the area of all loose and foreign material.

2. Lower the Patch Master heating unit parallel with the pavement. Heat and scarify the area to be filled.

3. Apply a rejuvenator (Pavement Savers, Inc. 540T) to the existing asphalt at the rate of .03 gallon per square yard.

4. Place the new asphalt material by hydraulically auguring it from the Patch Master’s heated storage compartment, molding it to the existing asphalt.

5. Compact with approved compactor or roller.

SPECIFICATIONS FOR REMOVING A HIGH AREA IN ASPHALT PAVEMENT

1. Clear the area of all loose and foreign material.

2. Lower the Patch Master heating unit until parallel with the pavement heating the asphalt to _ inch below the grade desired.

*3. Rake off the asphalt material _ inch below desired ground and place _ inch new asphalt.

4. Compact with an approved compactor or roller.

5. Apply a rejuvenator (Pavement Savers, Inc. 540T) at the rate of .03 gallon per square yard.

* NOTE: Depending of the aggregate size of the asphalt material, it may be necessary to remove below the grade desired and add new asphalt material by hydraulically auguring it from the Patch Master’s heated storage compartment.
