Abstract
A paving machine comprises a material bunker for receiving a construction material, a chassis, an operator stand which is arranged behind the material bunker when seen in the construction direction, a paving screed which can be leveled for assembling the construction material onto a substrate, a material conveying unit which is configured to transport the construction material from the material bunker to the paving screed, and at least one optical projector which is configured to generate at least one projection in the visible spectrum on the substrate laterally and/or in front of the chassis of the paving machine when seen in the construction direction. The projection is visible to an operator of the paving machine from the operator stand when seen in the construction direction.
