    might sound like a stupid quedtion but bugging me for long time. how did the tippers/artics empty into hopper of paver during laying of blacktop in theport tunnel. i persume the bodies could not be fully extended due to height restrictions. (coat and had ready for obvious answer!)

    Completed tunnel height is about 4.9m (4.6 or so operationally), which would probably be enough room to operate a tipper truck (carefully...!)

    yea it may be that height in the centre but if the carraigeway was laid in 2 rips the height would reduce alot towards the sides..

    Good point. Maybe there's an ejector-type trailer for bituminous/asphaltic material?

    Probably used rigid tippers or maybe even dump trucks.

    Couple of shovels and whackers in the corners :)

    The tipper dumps the asphalt into the paver in the centre and the paver moves the asphalt out to the edge of the carriageway so tipper trucks wouldn't have been operating near the edges.

    The permanent lighting, venting and sensors weren't in place!
