Shuttle Buggy® MTV Now Features Hydraulic Drive

Roadtec announces the changeover from axles and gears to hydraulic motors that control each wheel of the Roadtec Shuttle Buggy Material Transfer Vehicle (MTV).

This upgrade makes the machine even easier to shift and operate. The hydraulic system and motors are easier to work on than the traditional axle arrangement. There will be less wear associated with the hydraulics, making the system more durable. The reliability and life span of the Shuttle Buggy MTV’s transmission will also benefit from the new hydraulic system.

The Shuttle Buggy MTV is a device that remixes segregated asphalt mix and loads it into the paver. It is well known in the asphalt road building industry that temperature and material segregation are major contributors to uneven density and end-of-load segregation and their associated flaws, such as pot holes. Remixing in the Shuttle Buggy MTV from Roadtec has proven to be an effective method of eliminating temperature and material segregation in the mix just before it is loaded into the paver. According to Western Association of State Highway and Transportation Officials (WAASHTO) study T9903, a temperature differential of 7°C or less, assures the possibility of even compaction to specified density.

Numerous infrared tests made in real-life working conditions have proven the Shuttle Buggy MTV able to consistently deliver mix with a temperature differential of 7°C or less. According to the WAASHTO study, roads built with these extremely low temperature differentials require far less maintenance, and can last twice as long as roads built with temperature-segregated mix.
