Proven Pothole Patching Technology at APWA Congress
The FP5 Flameless Pothole Patcher and the SP Series Spray Injection Pothole Patchers from Bergkamp were on display. Both pothole patcher models come standard with the InPave® Technology. InPave is an easy and effective way to monitor material usage, performance and location of each pothole, patcher and crew, through multiple data-reporting sensors that are strategically engineered into each unit. As potholes and cracks are repaired, the data is automatically gathered and transmitted to a secure cloud-based server, allowing data retrieval from any Internet-ready device. The data can then be used to generate customizable reports for managing, planning, budgeting and informing constituents and public officials. The FP5 Flameless Pothole Patcher reduces material waste with its insulated 3.9 m3 electric-heated hopper that keeps asphalt at a constant temperature and pliable for an extended period of time. Potholes repaired using the FP5 have a significantly increased life over the traditional “throw and roll” method. The damaged area is removed and squared off using the on-board, hydraulically driven pavement breaker. The air and tack wand blows out any remaining debris and applies the tack coating, which helps bind the new asphalt to the existing pavement. The material chute delivers the fresh, hot asphalt to the prepared area, and the onboard compactor then consolidates the material evenly with the existing pavement. SP Series Spray Injection Pothole Patchers are available as either a truck-mounted or trailer-mounted unit. Depending on your choice of patching techniques (manual boom controls or in-cab boom controls), truck-mounted versions of the SP Series, in an industry-first, can be custom-mounted on a conventional or cab-over chassis for optimum utilization of existing fleet vehicles. All truck-mounted units feature a front-mounted boom, providing a working radius of greater than 3.9 m in front of the truck for crew safety. Spray injection is a less invasive patching technique, and according to the Federal Highway Administration (FHWA), also has a significantly increased patch life as compared to traditional patching methods. The SP Series units repair the damaged pavement (both alligator cracks and potholes) in just minutes. Compressed air is first blasted through the unit’s hose to quickly and thoroughly clean out and dry the hole, and the damaged area is sprayed with asphalt emulsion. The operator then selects the proper gradation of aggregate from one of two chambers in the hopper to best match the characteristics of the road. The SP units feature three emulsion injectors in the rotating nozzle to guarantee homogeneous aggregate coverage and high-quality durable pothole repairs, which are self-compacting from the bottom up. To top it off, a protective layer of smaller, clean stone is applied, thus protecting passing vehicles from coming into contact with the asphalt emulsion. All SP Series units also feature a “variable air system” that greatly reduces rebound and material waste.
