The asphalt laying machine has a feed-out and distribution screw which brings material to the delivery position, and behind the screw, viewed in the work direction, is a sole activated by a vibrator which spreads and compacts the delivered asphalt. To lay two separate strips of asphalt filling the space between wheels, two units movable laterally are incorporated, each with a heater and a vibrator activator. They have manoeuvring units for individual movement, and a screening device permits spreading of asphalt only along the strip in line with the spreader units. |
