What is Superpave?

Superpave is one of our most in-demand aggregate materials. Extracted from the 'chat' piles leftover from the Four States' mining era, Superpave is characterized by an angular structure that prevents it from deforming under extreme pressure. This makes Superpave the ideal aggregate material for road and highway construction as it creates superior asphalt.

Can anyone buy Chat?

No, Chat is federally regulated. We can only sell Chat to federal, state, and local governments to construct asphalt.

How far will Williams Diversified Materials ship aggregate products?

We have shipped to states as far west as Nebraska and Colorado, east as far as Tenessee, and down to Texas and Oklahoma.
