2022 Schwarze Street Sweepers Roadpatcher Base

2022 Schwarze Street Sweepers Roadpatcher

The U.S. Department of Transportation’s National Research Council’s Strategic Highway Research Program (SHRP) Report deems spray injection patching as “the most economical and longest lasting method of pothole repair.” This is primarily due to the benefit of having a single operator and the average patch lasting 4-7 years.

A more recent report by the Minnesota Department of Transportation conducted a present worth analysis of spray patching vs. traditional “throw and roll” and found the cost of spray patching to be 1/3 the cost ($2.31 per patch vs. $7.17 per patch), again due to lower labor and the fact that spray injection lasted 4 years compared to throw and roll patches having to be refilled annually due to wash out from weather.

• The emulsion prevents moisture from penetrating the base

• Mitigates reflective cracking ahead of resurfacing operations

• Bonds to the asphalt making a smoother riding surface

• The RS-2 emulsion is water based, not petroleum based, resulting in a “greener” technology.

Combine the proven benefits of spray patching with the latest technology found in the Schwarze RP7 Roadpatcher and you have a cost effective and reliable program for transportation infrastructure. The Schwarze® Roadpatcher™ list of standard features includes:

• A vane feeder to meter the aggregate into the air stream by a positive air lock vane feeder which ensures consistent aggregate placement.

• Even emulsion coating of the aggregate from 4 spray heads at the discharge.

• Canbus computer system provides ease of operation and quicker maintenance troubleshooting.

• 4 axis boom and nozzle digital hydraulics are based on the same technology found in backhoes for smoother operation.

• Joystick control.

• A 92% compaction rate.
