Mostly erosion control, pipe out falls, pond out falls, steam banks, etc.. Around here it's classI, classII and classIII mostly. Larger the number larger the stone. Cut out the area and install nonwoven geofabric and install the stone. In extreme cases they will also grout it with concrete if there is enough water to move the stones around.

Probably depends on max GPM. A cu yd of water weighs 1700 lbs and if it's moving that is some kind of force. Twice the speed gives you 8x the force which is why speedboats gobble fuel.

Re: Rock And Gravel Names


Only terms I'm familiar with is what the local pit sells. Anywhere else the names are all different.

They have a a road base or parking base product they sell. I'd say it's 1 1/2" crushed and smaller with fines and some sand. They call it Grizzly (griz) Pack.

1B or #8 is pea gravel like they use under superior walls
2B or #57 is 3/4 clean gravel that is used under slabs and for drainage. The washed 2B is used in concrete.
2A modified is is 3/4" minus with fines. Used for road base before paving, driveways, pipe bedding, and structural fill.
#3 stone is clean crushed rock that is about softball size. Used for construction entrances, driveway base and gabion baskets.
#4 stone is clean crushed rock that is baseball size.
R-4 rip rap is rock that is the size of basketballs. Used for rock outfalls at the end of discharge pipes, slope stablization, storm water channel lining, river bank stablization.
R-5 rip rap is about the size of beach balls.
R-8 rip rap is about the size of volkswagons. We hauled a bunch of R-8's to a contractor that was doing a bridge across a river. They used it to build a causeway across the river. One other truck ripped his tail gate right off dumping it and it fell into the river. Luckily the excavator operator was right there and fished it back out.

Re: Rock And Gravel Names


We have "clean" which would be only the size....3/4 clean is just 3/4.

Then we "blends" which would be the size and less....3/4 blend nothing bigger than 3/4, but smaller crushed mixed in it.

Re: Rock And Gravel Names


Where I work (a rock quarry), we use these names........

2" clean = #4 Railroad ballast or just #4
1 1/2" clean = 57s
1" clean = 67s
3/4" clean = 7s
1/2" clean = 8s
1/4" minus = 10s

1 1/2" minus (or "blend" or "base") = 610s
1" minus (or "blend" or "base") = DGA (Dense Grade Aggregate)

There are more within each size, depending on the spec the customer wants. The specs come from the ASTM manual...

...uhh, it's a pretty dry read, so just take my word for it

EDIT: Got me with the 2 year old thread....dammmmmmit.

It's all good. I'm still interested in hearing about local variations for gravel grades.
