When submitting samples (Micro-Deval) to the CO in accordance with ODOT S1010 please record the following information in CMS:

A. Create a sample ID for the Micro-Deval sample (District).

B. Create an 01 (this one is created automatically), 02, 03, 04, 05, and 06 sample (sample suffix) to cover all six (6) micro-deval samples. You may chose to perform a gradation or not. If not, you will need to enter in a generic gradation to fulfill the CMS requirement to allow us to access the sample testing screens. Please note that if a producer has stated in their revised QCP that they have increased the crushed count of their material that you will need to perform both a gradation and a fracture count for all (6) samples (District).

C. Record all information in SAMPLE screen as normal, except RECORD the producers sample identification for their six (6) samples in the respective (01-06) sample ID using the SAMPLED FROM field. By doing this you will allow ODOT to compare our MD values with the values reported by the Producer or Producer choice of private test lab (District).

D. Label the six (6) micro-deval sample with the appropriate sample ID (01-06). Submit the samples to Columbus for testing (District).
