DOT Density Testing and Inspection: Checklist for the Twelve-Inch Layer Method Mobile App
The DOT Density Testing and Inspection: Checklist for the Twelve-Inch Layer Method mobile app has been prepared to document procedures used by the Department of Transportation (DOT) to assure quality in density testing and inspection in the field.
How does it work?
This app is intended to train and aid technicians performing density testing on DOT projects. Technicians performing field density testing must be certified and evaluated as necessary by Independent Assurance Test (IAT). The app includes a detailed Twelve-Inch Layer Method Test.
