Pothole Patcher - How It Works!



Kenworth Crew Cab with a Bergkamp Pothole Patcher
 
By Steve Taylor

I spotted a crew working a new Bergkamp FP5 Pothole Patcher while driving through my neighborhood in Tampa, Florida. I understand Hillsborough County bought 6 of these babies to take care of the potholes in County Roads.

I thought I'd stop and take a few pictures of this truck and then provide an explanation of the operation of the process.Many years ago I had the opportunity to operate a similar work truck.

 
Berkamp Patcher-Filled with Hot Asphalt and Ready to Work

How it works:

Usually every working day the truck is loaded with hot asphalt at a local asphalt plant. It then goes out and patches potholes that day. It can be kept heated overnight if all the material is not used up.

This truck has many features not found on all others, first of all is the Kenworth Crew Cab. This cab will accommodate the whole crew for big jobs without bringing another vehicle to transport them. If my research is correct, this cab is a custom addition to the standard Kenworth cab.

The patcher body is a Bergkamp model FP5, it will carry 5.1 cubic yards of asphalt.The FP5 has a hydraulic-driven AC generator, providing onboard electric hydraulic power at all engine or travel speeds. 

The hopper heaters are using 220 VAC 4 kW electric heaters. It has a full hopper length auger which is hydraulically driven and reversible. There is an apron at the end of the auger.. The multi-spool control valves operate the hopper auger, agitator, doors and auxiliary tools,and have a built-in adjustable relief valve.

It has an insulated 80 gallon ASME asphalt emulsion system tank, spray hose for spraying  the tack coat, a spoils bin to carry the debris from clean up, and a vibrating single drum roller compactor.with a 4 hp gas engine for compacting the asphalt. It has a hand torch for drying out the wet holes. As well, it has an arrow board and brackets for carrying the wheelbarrow and hand tools.

Another option on this truck is the InPave tracking system. Using the latest technology, it reports the patch location, the amount of material used and the temperature of the material being placed etc.The InPave System also maps the location of each reporting data point and allows you to click on it to review the status and full details. All this is reported back to management over the cellular system real time.

Bergkamp provides one year of free cellular data transmission service that allows for quick, reliable downloading of information. Moving forward, you can continue with this service or easily transition to a radio receiver system. You pick the method that works best for your needs and budget.
