The following information establishes procedures for LPA Federal-Aid Acceptance Sampling and Testing (FAST) for all Federal-Aid projects awarded and administered by MoDOT. If a local public agency receives federal funds from MoDOT but does not specify, the guidelines in this Off-Systems Guide Schedule for Federal-Aid Acceptance Sampling and Testing (FAST) table should be followed. The acceptance sampling and testing procedures for other materials and construction processes are to be as shown in other articles in the Engineering Policy Guide.

2 Gradation only for Type 4 and Stabilized Permeable Base.
3 One set of cylinders shall consist of 2 - 6” x 12” cylinder molds or 3 - 4” x 8” cylinder molds. To determine if ultimate (contractual) strength has been obtained, one set of cylinders must be tested and the average strength of all cylinders will determine ultimate strength of in place concrete.
4 Air and slump tests are required for each set of cylinders created.
