	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.

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.

	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.
