Aggregate and bitumen are loaded into the container.
PKP HotPatch 3
PKP HotPatch 3 is a container-based mobile unit engineered to produce hot-mix asphalt directly at work site or next to the repair. It is the answer wherever conventional asphalt plant logistics are too slow, too costly or simply impractical.
Asphalt repair right where it's needed
PKP HotPatch 3 is a container-based mobile unit engineered to produce hot-mix asphalt directly at work site or next to the repair. It is the answer wherever conventional asphalt plant logistics are too slow, too costly or simply impractical.
The unit has been developed to eliminate the bottlenecks of traditional asphalt logistics: long transport distances, high costs, and dependence on the operating hours or winter closures of fixed asphalt plants. Instead of temporary and low-quality cold patching, repairs are carried out immediately with durable, hot mix.
