Bus Ramp and Roads - S1.E18
Maddie is out and about exploring different ways to travel. She uses a special camera to find out how a bus ramp works to help people get on and off the bus. An animation shows how the ramp is hidden in a compartment underneath the doors and how airbags allow the bus to lower on one side. Next, Maddie joins a road-building team to see how a motorway is made of different layers and uses a special thermal imaging camera to see how the hot asphalt is laid.
