SAMPLE 4.2.2 – Mix Designs Earthwork Materials “Mix Designs” are generally not required. Source Characterization testing will determine whether specific Earthwork Materials sources meet the specification requirements for a particular material type required (i.e. Ordinary Borrow, Gravel Borrow, Special Borrow, etc.). 4.3 – Processing of Existing Materials Where On-Site excavate proposed to be used for Earthwork is found to not meet specification requirements, the following procedures will be used to process or blend the material to meet the requirements of a specific Earthwork Material Type: ▼ A blended material “Mix Design” will be developed by the Project Laboratory. ▼ A stockpile of the excavate, not to exceed one day’s production, will be blended with other material per the “Mix Design.” ▼ At the completion of blending of the stockpile, samples will be obtained and Source Characterization testing will be performed to confirm that the blended material meets the specification requirements. 4.4 – Material Storage and Stockpiling All Earthwork materials will be properly stored and maintained to prevent contamination or commingling of different materials. Storage and stockpiling procedures will be as follows: ▼ The limits of each storage or stockpile location will be clearly marked by grade stakes legibly marked indicating the corresponding Source Characterization sample number (i.e. SC-1, SC-2, etc.) contained in the Project “Soils Source Characterization Log.” ▼ All active/working stockpiles of Earthwork materials will be characterized in accordance with Section 4.2.1 above a minimum of once per week. 5.0 Quality Control Sampling and Testing The requirements and procedures to be used for QC sampling and testing of Earthwork are as indicated below. 5.1 – Lot and Sublot Sizes Each Lot of Earthwork material will represent material from the same source, be produced or obtained under the same controlled process, and will possess normally distributed specification properties. Each Lot will be divided into Sublots of equal size in order to assess the Quality Characteristics of the Lot. The Lot size and corresponding Sublot size for each Earthwork Item are identified in the following table.

All Earthwork samples will be obtained randomly in accordance with ASTM D3665. The random sample location for each Sublot will be determined by Station, Offset, and Depth within the Sublot. All random sample locations will be documented on NETTCP Standard Test Report Form D3665 or D3665RNG. A copy of the Random Sampling Forms is located in Appendix __ (see Note, page B–17). ABC Contractors will provide Transportation Agency a copy of the Random Sampling locations (i.e. completed NETTCP Form D3665) for each Earthwork placement operation, during the start of the placement operation each day. 5.3 – Sample Identification System All Earthwork material samples will be clearly identified as follows: ▼ Project Segment (i.e. 1, 2, 3) ▼ Material Type (i.e. Rock Excavate, Earth Excavate, Ordinary Borrow, etc.) ▼ Sample Type (QC, CIT) and Random/Non-Random ▼ Lot Number and Sublot Number ▼ Sample Location (i.e. Rte 99 Median, Borrow Subcontractor, etc.) ▼ Station, Offset, and Depth ▼ Sample Date ▼ Technician or Inspector
