Live Bottom Truck

Live bottom (or flo-boy) dump trucks (Figures 1-4) have a conveyor system at the bottom of their bed to unload their payload. HMA is discharged out the back of the bed without raising the bed (Video 1). Live bottom trucks are more expensive to use and maintain because of the conveyor system but they also can reduce segregation problems (because the HMA is moved in a large mass) and can eliminate potential truck bed paver contact (because the bed is not raised during discharge).
