UPM Frequently Asked Questions

Sufficient quantities (100 + tons) have a 1 year stockpile life, smaller quantities last several weeks to several months depending on conditions.

The UPM stockpile will form a protective barrier on the outside of the pile, which keeps the interior of the stockpile fresh. Do not disturb protective barrier until ready to use. Load from one end of the stockpile only.

Sealed 50-lb bags have a minimum shelf life of 1 year.

YES! UPM is available in winter, spring/fall, and summer formulas. These grades are designed for optimum performance during the various temperatures of application.

Upon compaction, the aggregate and asphalt interlock making the repair stable enough for immediate traffic. The surface of the patch will cure to the hardness of the surrounding pavement. UPM below the surface will cure at a very slow rate, Depending upon the depth of the patch. This slow curing process allows the patch to move with the pavement during weathering, expansion and contraction.

Approximately 10-lbs. of UPM per square foot @ 1" depth (compacted) or approximately 1.4 ton = 1 cu. yard.

NO! UPM is self-priming. The proprietary liquid asphalt used in manufacturing UPM provides a tenacious binding property to the walls of the area being repaired.

Hand tamper, vibratory plate compactor, rollers or compaction by wheel rolling with a vehicle are acceptable. Sufficient compaction of UPM after installation will increase initial surface stability of the repair and prevent rutting, pushing and raveling.

YES!UPM is designed for permanent repair even in wet potholes.

YES! UPM is ideal for repairing concrete pavements - including roadways, bridge decks, parking lots, etc.

UPM works...guaranteed!

YES! Contractors, municipalities, and Departments of Transportation have successfully overlaid UPM patches without "bleed-through", pushing or rutting.
