What the video doesn't show is the immense amount of prep work to get the subgrade base underneath the pavement nice and flat, compacted to a stable proctor value. It can take weeks just to get a parking lot prepped so it can be paved in an afternoon.
That is still a very impressive system they've got none the less. Beats anything I've personally seen.
It's what they call oil and stone. It's not the same blacktop roads you will find in the states. Basically they do it on dirt roads to keep the dust down then they have to put crushed fine stones on top to seal it up. It's like apples and oranges from this to blacktop. You see them doing it on roads they want to get another year or two out of the blacktop before they repave so they will fill the cracks with rubber and then oil and stone over it and then it'll seal it off for another year. They have to do it when it's hot out also so it sticks to the blacktop . One problem they have though is they have to put a bunch of extra stone down so the oil doesn't seep up through it so there is a lot of extra loose stone flying around when traffic is traveling over it, so they have to go slower so as not to make the stones fly and hit passing cars. Lots of cars get cracked windshields from this and also there's a chance to get damage to radiators as well. Just thought i'd tell everyone the difference between this and asphalt and why they do this.
Certainly could. I used to go to Kenya in Mombasa every Xmas and the roads never got any better. Best business to have out their is to have a tyre shop as your tyres wont last long on those roads

Cool video.
Many thanks
What kind of pavement is that?
Bitumen/Asphalt. WisH we could work like this in the UK. Our repairs can take years
Bitumin/Asphalt

Thanks jake . Really appreciate your comments
NYS Department of transportation could use that machine! Back home roads are constantly "under construction. Nice 👍
Kenyans could learn how to make roads like that.
Certainly could. I used to go to Kenya in Mombasa every Xmas and the roads never got any better. Best business to have out their is to have a tyre shop as your tyres wont last long on those roads
true
Many thanks
