I have this same stuff in my driveway, after each rain it packs down like concrete. My opinion it's better than pavement, especially passing over it with that roller!!
Theres a lot of fine (small aggregate) in that material, and it would seem something that makes it stick together. (Look how it sticks to the roller.) Like some sort of oil / tar. Almost 2 feet thick? Looks like it's a better road than a dirt road, maybe easier to maintain if it has some flex to it without cracking. Would like to see this road after 1 year and then 10 years. Great skill for the bulldozer driver.
Funny how even when the bulldozer stopped moving, the track sounds continued at the same pace as well as when it would slow down and so to go until forward or reverse
My grandfather had a grade hand. I never saw his equal until this guy. I certainly could never do it though I didn't do it as long as he had. If it had a blade Papa could cut grade with it.
It will increase the cost as compared with soil.I think there would be compaction and moisture issue There will be huge quantity of gabro+ mixture wastage. It's durability depends on consultant's approval and laboratory reports.
