Ohio county tests geosynthetic cementitious composite mat in culvert
The Ohio Department of Transportation’s (ODOT) Office of Hydraulic Engineering had interest in utilizing Concrete Cloth in a culvert lining/protection demonstration project. It would be used as a substitute to the ODOT standard practice of field-paving an invert with 3-in.-thick reinforced concrete. Administrator for the Office of Hydraulic Engineering Jeff Syar led the efforts to locate a suitable candidate project.
A 114-in.-by-77-in. corrugated metal arch culvert under state Rte. 732 south of Oxford, Ohio, was selected as a possible candidate. R.B. Jergens Contractors Inc. was under contract with the ODOT District 8 office to field-pave the invert. An inspection of the culvert by Milliken Infrastructure and District 8 personnel revealed that the minor deterioration and pitting of the invert made the culvert a suitable choice for Concrete Cloth lining.

The District 8 office executed a change order to substitute the field paving with Concrete Cloth. Approximately 1,000 sq ft of CC8 fabric was placed in the lower third of the culvert along the entire 62-ft length. The lining process took place in May of 2016 and was completed in one week by R.B. Jergens.
A recent inspection revealed the Concrete Cloth lining is performing well. District 8 Culvert Engineer Jeff Meyer expressed his satisfaction with the installation as well as the performance of the lining, and he will consider its use on future projects.
