Permanent Pothole Repair An Economical Option

The Town of Irondequoit, N.Y., recently overcame its significant pothole repair challenges by changing its patching methods. This beautiful suburb north of Rochester, N.Y., borders Lake Ontario, the Genesee River and Irondequoit Bay. With all of this water, natural precipitation and a fluctuating climate, town officials focus significant energy protecting its motorists and their vehicles from pothole damages.

Previous Methods Didn’t Quite Cut It

Irondequoit has a mixture of high- to low-volume roads that see anywhere from a few to thousands of vehicles per day. Originally, the town used a cold-patch material or hot-mix asphalt for what is commonly referred to as the “throw-and-roll” method. The end result was short-term pothole repairs and occasionally wasted time and material.

In the mid 1990s, the town purchased a propane-operated and oil-heated pothole patcher. Initially, the result was favorable because the unit provided a longer-lasting, more pliable product. The biggest obstacles were that the hopper was not insulated and the propane could not be used to heat the asphalt while the truck was in motion. When traveling from site to site, the material would cool down and become less pliable. At times, Irondequoit was disposing of inadequate asphalt material and often producing less than acceptable patch longevity.

Cost Savings, Convenience & Longevity

As a replacement, the town recently purchased Bergkamp’s all-in-one FP5 Flameless Pothole Patcher. The biggest advantage of the new unit is the electric-heated hopper that keeps the asphalt material warm while the unit is in motion or stopped. It uses an onboard hydraulic-powered AC generator to heat its insulated 5.1-cu-yd hopper, and keeps the material at a consistent temperature throughout the day. In addition, Jeff Graves, labor foreman for Irondequoit and a 28-year veteran in its department of public works, and his crew use the tools located at the back of the unit to perform a more permanent pothole-repair process:

  • The damaged pothole area is squared off
  • The old material is removed and remaining debris blown out
  • A warm tack coating is applied
  • Fresh, hot asphalt is delivered to the pothole
  • The asphalt is compacted

“With other methods, we would often revisit previously patched areas,” said Graves. “With the flameless pothole patcher, we can patch roads with high traffic volumes without worrying about them for a long time.”

Graves estimated he is saving up to 10 man hours some weeks producing new patches instead of performing repetitive repairs. The town has also lowered material costs. With the propane-operated pothole patcher, the town was unable to use approximately 10% of the hot-asphalt material purchased per week. At an average of $67 per ton last year, the town saved approximately $200 per week. In addition, by making fewer trips to the asphalt plant, the town saves on diesel fuel costs, wear and tear on the equipment and has increased on-the-job productivity.

Temperature Is No Obstacle

The weather gets very cold during Irondequoit’s winters, where single digits can become the norm. “We can go out nearly every day with this unit,” said Graves. “To test it out, I picked a nine-degree day with a stiff wind chill and parked it outside. After 90 minutes, the pothole patcher kept the material at the proper temperature. The pothole repairs are holding up very well with the thawing and freezing temperatures.”

Feedback from the residents regarding the new pothole patcher has been limited. So far, Graves said that he isn’t getting near the number of complaints as in the past.
