Pothole Patching & Maintenance
Bergkamp offers traditional or spray injection pothole patching solutions
Even a properly maintained road will at some time develop potholes which are hazardous to drivers and can damage vehicles. One of the most common ways potholes form is when precipitation seeps into the pavement. That collected moisture then freezes and expands during cold weather, breaking the asphalt loose so traffic can damage it very quickly – thus creating the pothole. The existing surface deteriorates daily as traffic pounds those areas.

Roads are our main form of transportation and it’s important to keep potholes to a minimum. Bergkamp offers both an all-in-one mechanical pothole patcher, as well as, a spray injection pothole patcher. The following compares some common methods used today for road maintenance:
Three Main Pothole Repair Methods
Methods of pothole patching fall into two distinct categories: temporary and semi-permanent to permanent. Temporary patching efforts should be reserved for weather conditions that are not favorable to a more permanent solution and for temporary restoration of pavement smoothness. More permanent patching methods require more care in reconstructing and sealing the perimeter of the failed area. These methods are a much better and longer term solution relative to both future failure and cost, plus they are more commensurate with the original design of the road. There are a few other random methods for pothole repair, but they are less productive and generally higher in cost.
Throw & roll
This antiquated method involves shoveling the hot or cold asphalt mix into the pothole from the back of the truck or hotbox and then compact it by rolling over it with a truck tire or hitting it with the back of a shovel.
This is one of the most common methods because of its low upfront costs, but often costs significantly more in the long run, because of the repair’s short life span and the additional equipment, resources, and labor required. The failure rate of these repairs is high and may cost as much as five times more than the cost of repairs done with superior methods and quality materials.
First you square off the pothole, remove debris, and apply tack coat for sealing out moisture and bonding the material to the repair. Everything you need to complete the repair is placed at the rear of the machine. The patching material is placed in the hole and compacted with a roller or plate compactor.
This semi-permanent to permanent method removes all of the distressed asphalt, leaving only sound material. By placing the patching material against straight, square edges, it will not push out. This method is endorsed by the U.S. Army Corps of Engineers, and can provide a patch with a long life-expectancy and professional appearance.
This semi-permanent to permanent method involves blowing out the damaged area with compressed air, spraying asphalt emulsion in the damaged area to seal and bond it, and then filling the pothole with a mixture of emulsion and aggregate.
You have the choice of two different gradations of aggregate with the Bergkamp system. The larger aggregate is used in the hole to match the original composition of the road. The smaller aggregate covers the repair with clean, dry, uncoated stones to form a protective surface that doesn’t track and may be driven on immediately.
Spray injection pothole patching provides a quick and simple pothole repair using a less invasive process. The repairs are completed in minutes! This allows vehicles access to the area sooner and minimizes traffic flow disturbances. This method is generally used when the repair must be done quickly and efficiently.
We provide pothole patching solutions such as the FP5 Flameless All-In-One Pothole Patcher, as well as, the SP5 Spray Injection Pothole Patcher.
