Gravel question

[Capstone]

Anyone know what type of gravel the state (Tx in my case) uses for asphalt roads.

I see large piles all the time on the side of the road. Usually dark grey and almost black sometimes. I assume they use it to mix for road building.

Looks 1” or less and very uniform size.

Sounds like maybe it is ground-up asphalt removed from the road before paving. ?

Why you buy asphalt, you specify the mix. Always go with the state highway mix. Contractors sell it and install it, but if you don't have in writing what the mix is, they will give you a cheaper mix and increase their profit.

Piles on side of road are for seal coat applications.
Spread hot liquid asphalt, and distribute the rock on top. Sweep off excess.

Not exactly sure what it is called

Here they call that chip and seal.

It's limestone chips here, because limestone is cheap and local.

Most all the secondary county roads, around here, use some form of crushed basalt and a smaller material - the size of rock salt. It's a mix. The big 'ol gravel trucks will dump a loooooong pile - right down the center of the road. The asphalt truck follows right behind - saturating this long pile. It's then spread and rolled. Locally this is called - chipseal.

This was done to the county road right here. After a couple two or three months it was still painful to walk on barefoot. The crushed basalt was sharp as razors.

Bet it smooths your tires also.

Here’s what I’m seeing. I’m thinking about putting it down over a crushed concrete base if I can find a source.

Yes, chip n’ seal a term used for it.

No/little fines in this material generally, won’t ever pack and setup above a hard base.

I see your point about it not setting up without fines.
