Guide Schedule for Federal-Aid Sampling

Some materials do not fall under typical QC/QA testing for an Independent Assurance Sample (System based) quality system, such as when there is not a contractor QC part to the testing or when MoDOT performs the QC and QA. The QC/QA tests for these materials are covered in the table below.


Type of Construction or Material Tests to be Made (if specified) Sampled Tested In Minimum Number of Tests
Stabilized Permeable Base Graduation SAA002UB Before compactions Field, district laboratory One per 5,000 tons (5,000 megagrams) or fraction thereof per specified graduation source. None required if less than 1,000 tons (1,000 megagrams) of a specified graduation.
Modified subgrade (sand-soil base, soil-cement base or soil-lime base) Graduation SAA002WA Before compactions Field, district laboratory One per 5,000 tons (5,000 megagrams) or fraction thereof per specified graduation source. None required if less than 1,000 tons (1,000 megagrams) of a specified graduation.
Liquid Limit included with gradation Before compactions Field, district laboratory One per project per specified graduation, per source. None required if less than 1,000 tons (1,000 megagrams).
PI included with gradation Before compactions Field, district laboratory One per project per specified graduation, per source. None required if less than 1,000 tons (1,000 megagrams).
