	The duty of ~~an aggregate~~ inspector is to ensure that only materials with initial evaluation and source approval are incorporated into the final product The inspector will verify that materials are produced from the ledges or source as stated on the mix design. ~~Aggregate inspectors~~ must be familiar with all ledge configurations in the district and be able to differentiate ledges in the quarry. Quarry visits should be made as necessary to visually verify that production is from the ledges as stated on the mix design. The ~~aggregate~~ inspector shall ensure that required sampling frequencies and testing procedures comply with the specifications.

	The QMP should list all of the testing and inspection practices routinely performed to ensure compliance with the specification and production of a quality product. Some MoDOT specifications list specific testing frequencies and the QMP should not undermine those frequencies without proper justification. Producer QA should follow the testing requirements as stated in the specifications and should only vary with justification. For producers that select third party QA testing the producer shall ~~indentify~~ a third party testing lab that is AMRL certified to perform tests.

	The frequency of MoDOT Quality Assurance Testing and Audits will be determined by the specification and EPG guidance for individual products. MoDOT Quality Assurance Testing of products should occur on a quarterly basis as long as the producer is manufacturing products for MoDOT use, otherwise MoDOT Quality Assurance Testing is not necessary. The most common audit will be a once a year audit of documentation in AASHTOWARE Project (AWP), including any test results. A good auditing practice is to choose an incorporated product from the producer and verify the records for that individual product. An audit may occur at any time when producer QC and Independent QA of MoDOT Quality Assurance testing does no compare or other continual non-compliance discrepancies occur.

A new formation is defined as one the department has not previously tested and approved for PCCP. It shall also apply to a new source of a previously tested formation if an examination of the new source indicates that the material may have different properties.

	Special investigations are instances such as testing a previously rejected ledge in combination with approved ledges or other situations the department chooses to investigate. Initial evaluation for new formations or special investigations for use in PCCP shall start with a review of the service performance of concrete pavement utilizing aggregate from that formation and source (or nearby source). The paving could be city, county, commercial, etc. As much documentation as possible on age, mix design, etc. should be collected and a field review of the installations performed. If service performance is poor, the review may stop at this point and no testing performed. If service performance is satisfactory, sampling and testing may proceed. Approval of formations for use in production of aggregate for PCCP will ~~require~~ completion of AASHTO T161 Resistance of Concrete to Rapid Freezing and Thawing.

	Samples are to represent the final product that has been produced to meet a definite specification and intended specific use. Source Approval samples will be required each year and should be obtained at the site of production. Source Approvals intended for PCCP, that have not previously been approved or tested for PCCP, ~~will~~ require completion of AASHTO T161 Resistance of Concrete to Rapid Freezing and Thawing. AASHTO T161 testing will not be required on a yearly basis, however, if physical properties of aggregate for a specific combination of ledges vary significantly from previous Source Approval samples, T161 testing may be requested by the Central Laboratory. Source samples, submitted to the Central Laboratory for testing, shall not be used for combination purposes such as trial mix or any purpose other than Source Approval. Source Approvals are required for each unique combination of ledges represented by the mix design. Only one Source Approval is required when fractions of varying gradations are produced from the same ledges. These samples will be obtained from production of the aggregate with district personnel verifying the ledge(s) for the product. If ledge configuration changes during production, a new mix design will be required, and a new Source Approval taken to represent the material produced. Sampling for Source Approval may be more frequent than yearly if changes in the material are observed.

	When multiple ledges are incorporated into the product, consideration to method of sampling should be given so the sample represents all ledges being combined. A representative sample shall be secured by obtaining three or more approximately equal increments, selected at random from a stockpile. When sampling during production, the increments shall be gathered over a period time sufficient to ensure the sample represents all ledges being combined. The increments shall be combined to form a field sample whose mass equals or exceeds the minimum recommended.

	It is extremely important that a sample be properly identified and that complete and accurate information relative to it and the material represented be furnished to the Central Laboratory. A sample record must be completed in SM, on which all pertinent data regarding the sample is shown. This is essential in order to have the proper tests made in the Central Laboratory and the results properly reported to the field.

	The sampler should assign an identification number to each sample (refer to the QRG [[:Category:101 Standard Forms#Sample Record General Information \|Sample Record General Information]]). This number is to be shown on the sample tag, one tag attached to the bag and one tag placed inside the bag, accompanying the sample. Show the identification number on the second shipping tag or separate piece of paper and place inside each sample bag. This procedure provides a simplified reference to the sample should the shipping tag become lost and it becomes necessary for the Central Laboratory to contact the sampler.
