A construction worker, in bright orange protective workwear walking beside an asphalt paver finisher, which is laying down new tarmac on a public road. He is holding a metal rake to clear any loose stones. A red and white sign is warning drivers of a ramp in the road where the levels are varied while work is taking place. The manual worker has his hand on a touch screen control panel to control the even distribution of asphalt which is being compacted onto the road. Steam and smoke is rising from the hot asphalt being passed through the heavy machinery.
