CONSTRUCTION AGGREGATES MANUAL
PURPOSE To assign sampling and testing requirements to Aggregate Producers, and to establish compliance with the requirements of Chapter 14-103, Florida Administrative Code. AUTHORITY Section 334.044(10)(a) and (b), Florida Statutes (F.S.) Section 334.24(2) and (4), Florida Statutes (F.S.) Chapter 14-103, Florida Administrative Code (F.A.C.) SCOPE Principal users are the Aggregate Producers, State, State Materials Office, and the District Materials Offices. 1. SAMPLING, TESTING AND REPORTING 1.1. REQUIREMENTS FOR INITIAL SOURCE APPROVAL AND NEW-
PRODUCTS APPROVAL The producer must supply test data to the Department that indicates that each product from each process meets the quality and uniformity requirements of Section II of this Manual. Coarse and fine aggregate data submitted for Department evaluation with a request for initial source approval must represent 30 calendar days of production. Coarse and fine aggregate data submitted when seeking to add a product to an approved source's products list must represent a production period spread over a week (for Redistribution Terminals the data shall represent one shipment. If the quantity of material shipped is such that testing at Department-assigned frequencies does not yield sufficient data for approval, the material may be certified through a Conditional certification system). The following sections set forth the testing requirements for coarse and fine aggregate, base materials, and rip-rap. These data must have been produced within 90 days of an approval request. Approved test methods are listed in Appendix 20.

B. For aggregate shipments received at Redistribution Terminals from Type I and II mines, aggregate certification from the mine will be used in lieu of retesting at the Terminal for L.A. Abrasion (all types), limerock bearing ratio, acid insoluble, Atterberg tests, bulk specific gravity, absorption, and color. However, QC tests for gradation and passing #200 sieve will be required at the terminal.

established in Section (I) (A) 4 of this manual, per shipment received from Type III mines.
D. In addition, depending upon type of aggregate, size, usage and specific
properties and characteristics, additional tests and frequencies will be set by the Department according to contract specification requirements.
1.3. REPORTING AND RECORDING Data submitted electronically will not require codesheets. All data including worksheets and Department standardized computer codesheets will be available to the Department mine inspector at the mine and transmitted to the Department within the limits set for each variety of test given below and are partly dependent on the sampling and testing frequency. Availability at the mine may be considered the test results received verbally from the producer’s QC laboratory to be followed by codesheets (where applicable) and worksheets, as per Table 9 below.

2. AGGREGATE COMPLIANCE LIMITS AND STANDARDS
Standard statistical analysis shall be performed on the most recent thirty (30) QC test results of each aggregate code, grade, or type of aggregate from each operation when available. When the quality or uniformity of the aggregate is such that there is low testing frequency or a producer's QC program is inactive resulting in a smaller number of test results, all QC results less than one (1) year old from date sampled will be analyzed to verify an existing frequency or establish a new frequency even if the total numbers used in the analysis is less than thirty (30). The Department will perform Verification tests to evaluate the effectiveness of the producer's Quality Control Program. Standards of evaluation shall be as set forth in the Department's "Quality Assurance Monitoring of Mineral Aggregates" Procedure.
