Why Choose Our Mixers?

Why Choose a Roadmaster Volumetric Mixer?

Outstanding Concrete Mix Quality:

• Experts agree that the fresher the concrete is when applied, the stronger it will be, increasing the total quality. With a volumetric mixer, the concrete is made “on demand” or when needed,ensuring the freshest concrete possible.

• Volumetric Mixers are very flexible and can produce a 0-10” slump from the same load, giving quality concrete on site to match a wide range of specifications. Mix designs can be changed quickly to accommodate, in a manner of seconds, any mix requirement.

Lower Equipment and Initial Investment Cost:

• An investment in a volumetric mixer will normally be less than the investment in traditional methods employing a central batch plant with supporting drum mixers. The return on investment when compared to cost and production will strongly favor a volumetric mixer.


A volumetric mixer can be used as:

1. A stationary unit with a local power source (diesel, electric)

2. A mobile unit serving as an “on site batch plant”

3. A production on-site solution. Time and distance limitations that may apply to traditional methods do not apply. Concern of “hot loads” and water tempering are not applicable to the volumetric mixer.

Simplicity of Operation:

• Volumetric Mixers are simple to operate.

• Full view of the control station and the flow of contents during the mixing process.

• Easily adjust water and admix flow as needed.

• As long as the aggregate, sand and cement bins are supplied, the volumetric mixer can produce concrete continuously at a normal rate of 60-yards per hour (this may be increased as required).

Concrete can be Accurately Metered

• Volumetric mixers have a counter. This count is used to calculate exact volume or yield of concrete for separate deliveries to multiple job sites, regardless of the mix design.

• Where required, an electronic PLC monitoring system can be included to provide accurate details of the mix, similar to that offered by central batch plants. Every load can be monitored by time and date.

Modular design

  • All major components are manufactured separately, painted and then assembled. 
  • Modular process requires exact tolerances. The result is a precision-built, superior-performing mixer. 
  • Component capacity upgrades and interchangeability of major components are easily accomplished.

Concrete delivery system

  • Accuracy and consistency: the right mix for the right environment in the right quantity, eliminating over- and under-billing issues. 
  • Full-load utilization: unlike drum mixers, the entire contents of a volumetric mixer is available for use. 
  • All concrete contents can be completely emptied from the concrete bin
  • All Roadmaster mixers perform at DOT standards, and exceed them in many cases.
  • Hydraulic motor drive (standard) for infinite flexibility in mix design and lower maintenance costs. 
  • Advanced mixing auger with longest-lasting, most durable wear-blades in the industry. 
  • Auger shoes with 700 hardness, ensuring maximum life capacity
  • Solid flighting and shear design enables full rate production at a 45-degree angle (six-foot end height) up to an eight-inch slump
  • All our trucks pass the Caltran C109 specification for cement and concrete standards each month
  • Bolt-on design for easy maintenance and parts replacement
  • Unparalleled customer service and support
  • Steel parts
  • Easy access to gears, chains and the auger 
  • Five-ply belting system with a brush-applied oil system
  • Pre-assembled parts painted with high-strength industrial paint
  • Up to 12-yard capacity
