Potholes are holes in the roadway that vary in size and shape. They are caused by the expansion and contraction of ground water after water has entered the ground under the pavement.
When the water freezes, it expands and will take up more space under the pavement causing the pavement to expand, bend, crack and weaken the roadway material. Then when the ice melts, the pavement contracts and leaves gaps or voids in the surface under the pavement. Cars and trucks passing over the weak spot in the road cause the material to be displaced or broken down from the weight, creating the pothole.
The Schwarze® Roadpatcher™ is the most efficient, consistent and versatile system available to fix these potholes. It is also the safest way to perform road maintenance because it requires only one operator who works from the driver’s position in the cab.
The Schwarze® Roadpatcher™:
Cleans – Dust and debris are blown from the pothole by a high-velocity blower. The Operator is located in the cab eliminating being exposed to traffic and reducing the risk of potential personal injury.
Tacks – Asphalt emulsion is sprayed to seal the surface and create a binder for the repair. A nozzle tilt allows for more efficient movement of rock when cleaning the repair and reduces rock bounce.
Fills and Compacts – Asphalt emulsion and aggregate are combined to create a quality and durable high-density repair. With a 95% compaction rate based on the Strategic Highway Initiative Testing without the use of compactors.
Dry coats – The repair is topped off with aggregate to allow immediate traffic on the new surface. Has more consistent flow of aggregate than other systems. The operator can switch between 2 conveyor speeds for dry coating or skin patches
