The truck-mounted SP5 and SP8 Spray Injection Patchers are equipped with a dual-chamber (60/40) aggregate hopper that allows the distribution of two different gradations of aggregate for repair of deeper potholes.
A version with automatic operations from the cab is available, in addition to a manual operations version operated from the ground in front of the truck. The trailer-mounted SPT Spray Injection Patcher will feature manual operations. Spray injection is a less invasive patching technique that allows the damaged pavement to be blown out and repaired in minutes, Bergkamp says. Truck-mounted units are operated at the front of the unit thanks to the front-mounted boom, which provides a working radius of up to 13 feet.
