Roadtec is changing from axles and gears to hydraulic motors for the control of 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; and the new hydraulic system will help improve the reliability and life span of the transmission.
Remixing in the Shuttle Buggy MTV 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 WAASHTO study T9903, a temperature differential of 7°C or less, assures the possibility of even compaction to specified density; and 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.
