DOT Approved Aggregates

Pattison sand company state DOT spec Aggregate formations

Geologic age matters when it comes to aggregate physical properties. Older rocks are generally more competent and less absorptive for various applications such as Portland Cement Concrete Stone and Bituminous Asphalt Stone. During initial development of our long-term quarry operations, we will be mining the Oneota and Shakopee Dolomites. These represent superior grade State DOT specification aggregate. They are desirable for concrete stone, asphalt stone, manufactured sand and rip rap. In fact, Iowa DOT has developed a specific quality characteristic for Oneota manufactured sand because of its physical and geological properties.

Pattison has received approval from the State of Iowa DOT and is working on certifications from neighboring states including Illinois, Minnesota, Missouri, Nebraska, North Dakota and Wisconsin. The same is true for the various Army Corp of Engineers Districts in and around Iowa. We have received FAA certification for airport runway construction projects.
