ROADPATCHER (CHASSIS MOUNT)

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.  Report: fhwa.dot.gov/publications/research/infrastructure/pavements/ltpp/99168/99168.pdf

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.

This system creates the highest quality patch available.

FEATUREBENEFIT
No unsealed connectors, all silicone sealed connectionsIncreased uptime with the use of severe duty wiring that eliminates shorts caused by poor connections.
Custom Made and Flushed Hydraulic HosesReduces the opportunity for contamination in the Hydraulic System.
CNC Laser Cutting & Forming ProcessGuarantees a consistent cut part every time
Fully ShroudedProtects all components from Mother Nature and allows cold temperature operation
Mix on DemandEliminates the end users dependency of commercially premixed materials.
Clean, Tack, Fill & Compact, Top Layer, & Immediate Traffic Flow92% Compaction rate based on the Strategic Highway Initiative Testing without the use of compactors.
6.5 Cubic Yard Aggregate Hopper & Variable Speed Conveyor Feed SystemMore consistent flow of aggregate than other systems. Operator can select conveyor speeds for dry coating or skin patches.
Nozzle TiltAllows a more efficient movement of rock when cleaning the repair area, and reduces rock bounce.
Twin Engine SystemAllows for patch on the go, and increased productivity.
Heated Emulsion PresetsTakes the guesswork out of the amount of emulsion the operator applies to the aggregate. This feature allows the operator to preset the amount of emulsion desired. When ready, press a button to initiate coating the aggregate. Improves the consistency of materials from one repair to the next.
Hydraulic Valves enclosed within bodyValves are located within the patcher body, and are not exposed to the elements. Readily accessible for servicing.
8 Hole Emulsion Spray RingHaving 8 holes in the spray ring allows a more even coat of the aggregate, and increases the life of the repair.
Rectangular Debris HopperAllows for ease of loading.
Quick Disconnect Aggregate HoseReduces downtime during maintenance .
FEATUREBENEFIT
6.5 Cubic Yard HopperHauls more gravel for improved performance.
300 Gallon Emulsion Tank (or Optional 400 Gallon)Allows for fewer refills during the day for better productivity.
Heated Emulsion PresetsTakes the guesswork out of the amount of emulsion the operator applies to the aggregate. This feature allows the operator to preset the amount of emulsion desired. When ready, press a button to initiate coating the aggregate. Improves the consistency of materials from one repair to the next.
Nozzle TiltAllows a more efficient movement of rock when cleaning the repair, and reduces rock bounce.
PUBLIC SAFETY FEATURESBENEFIT
Operator Located in the CabEliminates the operator being exposed to traffic, and reduces the risk potential personal injury. Increased operator Comfort and increased productivity.
Backup AlarmVariable output backup alarm adjust automatically above the surrounding noise levels
LED LightingIncreased Visibility on the streets, and reduced cost of ownership.
Integrated Directional Arrow BoardSafely directs traffic during operation.
Heads-up CAN Bus Control SystemKeeps the operator focused on the road during operation.
Electric Emulsion ValveIn Cab controlled prevents the operator from having to leave the safety of the cab.
Large Work PlatformAllows safe access to the aggregate feeder.
VALUEBENEFIT
Head up displayLarge easy to see 7″ TFT CLD Color display. Displays step-by-step patching process while informing the operator of system functions, conditions and alarms. Retains memory even if power is lost.
Hydraulic Test PortsReduces troubleshooting time
Emulsion Heating SystemDuring Operation engine coolant keeps the emulsion at, or near 150 degrees. Can patch in Cold temperatures.
Fully ShroudedProtects all components from Mother Nature and allows cold temperature operation.
Mix on DemandEliminates the end users dependency of commercially premixed materials
Hydraulic Valves enclosed within bodyValves are located within the patcher body, and are not exposed to the elements. Readily accessible for servicing.
Quick Disconnect Aggregate HoseReduces downtime during maintenance
Rectangular Debris HopperAllows for ease of loading.
