Standard Practice for
Independent Assurance (IA) Programs
AASHTO Designation: R 44-07
SCOPE AND LIMITATIONS
1.1.IndependentAssurance (JA)-IA is used in industry as an internal audit and review to support the accuracy of data and processes.
In the highway industry it is the outgrowth of a report from the Congressional House Committee on Oversights and Investigations (“Blatnik Committee”) that
requires state departments of transportation (DOTs) to perform IA sampling and testing whenever federal funds are involved.
1.2.Purpose of IA-IA is an unbiased and independent assessment of all sampling, testing, and workmanship.
This assessment includes evaluation of procedures and equipment used for the acceptance of highway materials and construction. 23 CFR Part 637 requires each state to have an IA Program.
IA is used for verification of sampling procedures, testing procedures, and testing equipment.
1.3.IA is distinct from, and not intended as an acceptance process or for use in, verification of contractor sampling and testing results.
IA is distinct from, and not intended for, quality control (QC) purposes.
IfIA results indicate a potential problem with quality, the results may be used to initiate additional testing.
