This is insane. The rocks need to be super small and crushed have the capacity to compress. That's what gives it strength. Compression. Go look at asphalt quality around the world and we have the worst knowledge on asphalt quakity and education. That underlayment is also bad its not comoressed and needs to be pours.
Chill...this is a driveway, not a highway. We did the compaction in layers to ensure best possible consolidation. I just did a 5 month inspection, and you would be surprised, ZERO cracks! The method works. And the whole point of this video is to make it approachable to home owners. Hey, at least we didn't just pour those cold patches directly over failed asphalt 😆.
