Dusty Spalls

Dusty Spalls-sounds like the name of a cowboy in an old “B” western film. These quarry spalls came with enough crushed rock dust to create a fugitive dust cloud when dropped into a “skip” box.

Excellent Tire Wash

This here is an excellent tire wash. Why? Because it is long enough for two tire rotations. In addition, quarry spalls are installed at the entrance and exit of the tire wash. To the left of the tire wash, the contractor placed quarry spalls so vehicles entering the project don’t have to drive through the tire wash.

Berm for Quarry Spalls

This would not have been my choice as a berm for quarry spalls; straw wattles are too light to use on asphalt and they allow water to flow under them. A compost sock, being heavy, would work better, though, they are prone to tearing. An asphalt berm might be best here.

Fancy Rock Entrance

I saw this fancy rock entrance on the way to work and thought it was amusing on the surface. Really, though, I think they needed the elevation to access the upper part of the site. That’s a nice mini excavator.
