Temperature and material segregation are major contributors to uneven density and end-of-load segregation and their associated flaws, such as potholes, but remixing in the Shuttle Buggy MTV from Roadtec is said 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; numerous infrared tests made in real-life working conditions have shown that the Shuttle Buggy MTV is able to consistently deliver mix with a temperature differential of 7 degrees Celsius or less.
