Most of our gravels will meet State DOT requirements. Our gravels range from 35% to 95% non-calcareous (acid insoluble), making them suitable for applications where acid and wear resistance are important.  

A note about rock sizes: The rock screening and sorting process works well, but there will always be some variation in each load of rock.  For example, the screen with a mesh size of 4” x 4” tends to sort out rocks in the 2” – 4” range.  However, it is possible for rocks 4” in diameter but longer than 4” to slip through the mesh along with the smaller rocks.
