This excellent construction machine is very INCREDIBLE. Modern concrete paving machines technology.

 Awesome video, that I found to be strangely serene and beautiful.
As an amateur, I have done a fair amount of concreting myself, so I know it can be very hard work:  Awesome !! African countries let’s unite and develop our continent through these kind of innovations.
but these guys, with their ingenious machinery, made it all look so easy.  I enjoy watching this type of video. But it would be even better to show a finished product. For example, what was the conical concrete structure that was first shown used for  The best I can tell,  the concrete was coming into the pour via an overhead belt  (see 3:34) which was  truck mounted belt    You get one screenshot of the belt/truck in background. (@2:47)  Many shots of the belt operator with his control box.   This is kind of a misleading vid of the first pour as the roller/slurry technology is doing only the finishing work.  (You can see the small slurry finishing mixer in the background and the hoses leading to finishing slurry pipe the flat workers are using.  It took me a bit to figure this out as I have not been in the industry for some time.  Concrete is the worst pavement for roads, it's more noisy in your car when you drive on it and when it cracks or has expansion joints it makes awful bumps. Sure it's cheaper but I don't get why some countries in the developped world are still using concrete ; asphalt is way better for road pavement.
