Heavy machines represent the heartbeat of American construction, pounding progress into the nation's infrastructure.Would it not be better if the lorry when emptying the gravel, he drove forward and levelled out the gravel, making it flat instead of putting it into a pile.Dumping it in the middle is the best way to go but you got to have a dozer operator that knows what he's doing.That is some of the nicest and most consistent sized gravel I've ever seen, looks like coal. I'm not sure how skilled the operator is, these conditions are not much of a test of skill, it's like a dream come true. Sub base is smooth and level, gravel is consistent size, I would feel like a cat in a sand box!
