Our History
CMTG was formed in 2014 as a joint venture between Superior Bowen and Clarkson Construction to perform Quality Control for the Kansas Department of Transportation (KDOT)’s massive Johnson County Gateway Project. In late 2014, CMTG completed its AASHTO accreditation process in Hot Mix Asphalt (HMA), aggregate, asphalt binder, and soils testing. In 2018, Superior Bowen purchased Clarkson’s interests, making CMTG a wholly-owned subsidiary of its family of companies.
