Slurry Seal & Micro Surfacing

RoadSavers are the finest slurry seal & micro surfacing machines in the world. As the flagship product line from Rayner Equipment Systems, RoadSavers represent the quality & reliability that Rayner Equipment is known for.

Better steel, better components, & Operator-friendly design separate RoadSavers from other slurry seal & micro surfacing machines. With over 35 years of testing & hundreds units throughout the world, RoadSavers have proven to be Relentlessly Reliable.

Slurry seal & micro surfacing applications require precision, which is why all functions on RoadSavers may be monitored with a glance or controlled by fingertip, allowing the Operator’s attention to remain focused on the material being applied. Many features now found on equipment from our competitors, such as joystick controls, originated on a RoadSaver. Now the next addition to the RoadSaver line, the IIIG, further separates from the competition with a new design that requires No Side Engine.

Additional Features

T1 Steel

Also known as “Bridge Steel” or “Skyscraper Steel,” T-1 is designed for use in high stress applications & offers RoadSaver owners longer life free of deformation, hopper wear, tank splitting, rust & flexing issues. With over 300 RoadSavers around the world, we have never had a tank split, a hopper wear out or frame issues of any kind. Pugmill liners often last twice as long as A36 steel liners used by our competitors. Pugmill paddles have much higher resistance to bending, deformation & wear & the entire machine maintains its own structural integrity separate from the truck it is mounted on.

Traction Master Conveyor System

The Traction Master provides the longest service life in the industry. The belt is self-centering & designed for proper material flow from the front of the machine to the back through a designed incline assuring constant supply and density of material.

Emulsion Filtering System (Optional)

When truck configurations allow, the emulsion pump is mounted below the emulsion tank allowing an increase in available head pressure, less potential cavitation and more positive flow to the pugmill. This design also allows placement of an optional high volume, dual inlet suction filter.

Care In Manufacturing

All electrical and hydraulic lines are professionally mounted, secured and properly run. On RoadSavers, you will never find them run in a common trough or unprotected through steel bulkheads like you see on machines made by our competitors. Should you ever need to isolate a hydraulic system, your RoadSaver is equipped with a full set of hydraulic shut-off valves. The radiators we build for the Cummins engine are built at 200% of the Cummins engineering requirement, your engine runs cool all the time. All of our engine mounting, controls, cooling system & full run cycle are inspected & approved by Cummins to validate a world-wide factory warranty.

We provide a catwalk for safe inspection of water & emulsion tanks. We don’t offer this as an option; we provide it as a safety standard. We mount each machine on a steel rail bed, not a wooden one which will compress over time and become insecure; your machine is mounted securely & safely.

Hydraulic System

Premium Sauer-Danfoss hydraulic components provide dependability & worldwide support. Each powers its own system. One fixed pressure pump powers the accessory manifold, while two load sensing pumps power the pugmill drives & the emulsion pump/conveyor belt & spreader box systems.

  1. Each of the three hydraulic systems has its own filter & separator assembly to not only filter, but to eliminate both ferrous & nonferrous particles.
  2. Reserve cooling capacity allows full productions on the hottest of days.
  3. True hydraulic fittings used throughout, bulkhead fittings where necessary.

To ensure long life we only use hydraulic components that meet our strict criteria of durability, availability & tenacity. We use magnetic suction strainers to collect naturally occurring ferrous material from the oil. Our return filters use synthetic media not the cheaper cellulose; this provides reduced pressure drop & maximum contamination removal from the oil. All machines have a shut off valve on each suction line as a standard feature. This feature is extremely important if a field failure occurs or a replacement is required. Our hydraulic pumps all operate at least 1000PSI below the maximum “continuous” rating, thus offering a longer component life. The commonly overlooked area of hose & fitting selection has been carefully designed to reduce oil turbulence & pressure drop resulting in the best use of the engine horse power. We take extra steps to assure hose life including tough cover hose, hose wrap & bulkhead fittings, all of which are important to reduce abrasion, extend life & keep crews in the field working.

Emulsion Delivery System

A Blackmer positive displacement vane pump is used for long life & consistent output. Both the emulsion pump & the emulsion valve are heat jacketed & warmed by the Cummins engine for cold morning starts.

Liquid Additive System

Specially designed corrosive-resistant polyurethane tank with hydraulically driven, corrosion-resistant steel shaft, Viton Impentra Seal, & stainless steel hardware. The flow meter at the Operator Control Center allows precise adjustment.

Dependable Water System

A bent-axis piston drive system provides full water resources when you need it where you need it. The pugmill has full flow at all times no matter what other water systems may be demanding. The RoadSaver’s select bent-axis drives will provide extended service life as well as exceptional performance.

Hydraulically driven 130 GPM @ 110 PSI (492 L @ 760kPa) pump with diaphragm valve & available digital flow display for precise control. Water pressure is constant regardless of demand.

Vibrator System

Hydraulically driven vibrator beam suspended in the aggregate hopper with variable frequency & amplitude adjustments. Activated from Operator Control Center & controlled through the computerized Automatic Sequencing System.

Electrical System

12 VDC negative ground.

How it Works

Financing

From a platform at the back of a truck-mounted RoadSaver an operator can monitor aspects of material flow as he or she places an emulsified mix on a road surface. With the press of a button at the operator’s control center, the operator can set the computer-controlled, automatic sequencing material introduction system in motion. This introduction system allows timing adjustments for delivering aggregate, emulsion, water & additives into the pugmill where they are mixed & distributed to the road surface.

To pour an emulsified mix from a RoadSaver, the crew first delivers aggregate to the aggregate bin, which is designed to hold 12 cubic yards (9.2 cubic meters) & more of material. Aggregate travels on a hydraulically driven RoadSaver SuperBelt conveyor to the reversible, twin-shaft, twin-drive pugmill. A tank & a Blackmer positive displacement vane pump delivers the emulsion from the 60 gallon (227 l) tank, both located at the front of the machine, to the pugmill to be mixed with the aggregate.

For mixes that require other additives, a 90 gallon (340 l) liquid additive tank sits toward the back & on the right-side of the machine, delivering material via a hydraulically driven pump, which is adjustable at the operator’s station. A 16 cubic foot (0.45 cubic meters) fines feeder sits above the aggregate bin at the back of the machine, delivering material via a digital ratio meter, & is also adjustable at the operator’s station.

Once the materials are flowing to the pugmill at a metered & monitored rate, the multi-paddle pugmill mixes the materials & augers them out through the hydraulic gate & diverters to a spreader box, or other end attachment, at material output rates ranging from 2 tons to 4 tons mixed (1.8 to 3.6Mg) per minute. With the automatic sequencing material introduction system, the operator can set or control which material precoats the aggregate, & for how long, before the next material enters the pugmill.
