Norris Asphalt Paving Co. and Douds Stone

What Norris Asphalt Paving Co. and Douds Stone does

Norris Asphalt Paving Co. and Douds Stone, LLC are two related privately held companies operating jointly under common ownership in southeast Iowa. Norris Asphalt Paving Co. is an asphalt paving contractor running 5 hot-mix-asphalt (HMA) plants and 3 paving crews, producing and laying approximately 400,000 tons of HMA per year across highways, county roads, city streets, driveways, and parking lots. Douds Stone, LLC — established in 1923 — operates 12 open-pit quarries and 2 sand operations that supply crushed limestone, sand, gravel, rip-rap, erosion stone, aglime, and subbase materials, providing internal aggregate feedstock for the paving business and external sales to aggregate buyers.

The company is a vertically integrated regional heavy-civil and aggregate producer, anchored by a 19-site physical footprint across Iowa and one quarry in Wayland, Missouri. Its operations span the full road-construction supply chain: aggregate extraction (Douds Stone), HMA production (Ottumwa, Harvey, Danville, and other plants), paving execution (3 crews), and freight (Allen Trucking, LC subsidiary). The technology stack is conventional — HMA production with up to 20% reclaimed asphalt pavement (RAP), limestone quarrying, and aggregate washing — supported by an in-house quality control department for mix design and DOT-certified materials.

Norris/Douds sells through enterprise field sales to government buyers (Iowa DOT, county road departments, city municipalities) and a smaller commercial/residential book, using quote-based, project-specific pricing. A Material Calculator tool on the website and an InkSoft-powered online store are the only transactional digital channels. Revenue is concentrated in southeast Iowa with some northern Missouri DOT work; pricing is pay-as-you-go per project. The business has earned the Sheldon G. Hayes Award (2015), is a 6-time finalist, and has held NAPA Diamond Achievement certification for Plant 350 from 2007 onward.

Direct peers

• Rogers Group, Inc. Privately held aggregate and asphalt producer operating crushed stone quarries, sand and gravel operations, and asphalt plants primarily across the Mid-South and Midwest. Closely comparable as a privately held, vertically integrated aggregate-and-asphalt operator.
• Granite Construction Incorporated: Heavy civil contractor and vertically integrated materials producer operating asphalt plants, quarries, and paving crews across the US, with significant activity in transportation infrastructure. Highly comparable business model combining asphalt paving services with aggregate supply.
• Summit Materials, Inc. Vertically integrated construction materials company producing aggregates, cement, and ready-mix concrete with substantial asphalt operations in the Midwest and Mountain regions. Comparable materials-production-and-paving business model.
• Knife River Corporation: Vertically integrated aggregates, asphalt, and ready-mix concrete producer with operations across the western and midwestern US prior to its acquisition by MDU Resources. Closely mirrors Norris's integrated quarry-to-paving model at a larger regional scale.
• Irving Materials, Inc. (IMI): Family-owned producer of aggregates, ready-mix concrete, and asphalt in Indiana and the broader Midwest, operating multiple quarries and plants. Directly comparable in business mix, family/privately held ownership profile, and Midwest regional focus.

Broad incumbents

• Martin Marietta Materials, Inc. One of the largest US producers of aggregates and asphalt mix, operating across multiple states with a much broader footprint than Norris. Directly comparable end products (HMA, crushed stone) but at national scale and as a public company.
• Vulcan Materials Company: Largest producer of construction aggregates in the US with substantial asphalt operations in the Southeast and Midwest. Comparable products (HMA, crushed limestone) but operates nationally as a public, broad-line incumbent.
• CRH plc (Oldcastle Materials): Global building materials giant whose US subsidiary Oldcastle operates a large network of asphalt plants, aggregate quarries, and paving services. Direct overlap in asphalt paving and aggregate production but as part of a much larger, diversified portfolio.

Regional players

• Bituminous Roadways, Inc. Asphalt paving and production company serving the Minneapolis-St. Paul metro area and Minnesota. Comparable as a vertically integrated asphalt paver with plant and crew operations, though primarily serving a different Upper Midwest geography than Norris.
• Dolese Bros. Co. Privately held producer of crushed stone, ready-mix concrete, and asphalt products primarily serving Oklahoma and surrounding states. Comparable materials-and-paving business mix with similar private ownership profile, but in a different regional market.
