Asphalts

Asphalt is a material refined from crude oil and used in road construction and roofing application as well as a wide range of specialty products. Calumet produces asphalt at three refineries, Princeton, LA, Shreveport, LA and Great Falls, MT.

Our Princeton refinery produces materials used in the roofing industry, primarily coating asphalt used in the manufacture of shingles. Our predictable crude slate means our asphalt has consistent properties.

Our Great Falls refinery produces materials used primarily in road paving applications. As with Princeton, our predictable crude slate means our asphalt has consistent properties. We ship our asphalt by both truck and rail, broadening the reach of our customers.

Shreveport produces asphalts used across a wide range of industries. Shreveport’s propane de-asphalting unit produces a unique low penetration asphalt. As with Great Falls, we ship our asphalt by both truck and rail, broadening the reach of our customers.
