11. Acceptance criteria. 5-06.3(2) Pervious Concrete Mix Design The Contractor shall provide a mix design for pervious concrete and shall submit the mix design to the Engineer in writing. Pervious concrete shall not be placed in the test panels without a mix design that has been reviewed and accepted by the Engineer. 5-06.3(2)A Mix Design Criteria The Contractor shall include the following elements and results of the described procedures in the proposed mix design: 1. A unique identification number for the mix design that is approved for the Job Mix Formula (JMF). 2. Portland cement shall be Type I, Type II, Type I-Il Type IP, or Type IS. 3. The cementitious content, including pozzolans if used, shall be a minimum of 480 pounds per cubic yard. 4. The mix shall incorporate a hydration stabilizing admixture. 5. Synthetic microfibers may be utilized at the manufacturer's recommended dosage rate. 6. The water/cement ratio shall not exceed 0.35. 7. No more than 25 percent of portland cement in the mix, by weight, may be replaced by fly ash, ground granulated blast furnace slag, or a combination of both. 8. Coarse aggregate shall conform to Section 9-03.1(4), AASHTO Grading No.8. 5-06.3(2)B Job Mix Formula (JMF) The approved mix design established through the approved test panel becomes the JMF. 5-06.3(3) Submittals In accordance to Section 1-05.3, the Contractor shall submit the following items to the Engineer for acceptance prior to placing any pervious concrete pavement: 1. The source of all materials proposed for use in constructing pervious concrete pavement. 2. Batch weights for all constituents of one (1) cubic yard of the proposed pervious concrete mix. 3. The specific gravity (SSD) of all aggregates to be used in the proposed pervious concrete mix. 4. The proposed gradation of coarse aggregates used in pervious concrete. 5. The designed volume in cubic feet of all proposed components for 1(one) cubic yard of the proposed pervious concrete mix. 6. The design water/cement ratio of the proposed mix design. 7. The fresh density of the proposed pervious concrete mixture as determined by ASTM C1688. 8. Catalogue cuts and Certificates of Compliance for all proposed admixtures. 9. Mill Certification of the portland cement and pozzolans, if used, for the current lot to be used in the production of the proposed pervious concrete mix. The Contractor shall maintain this submittal throughout the duration of the project as lots change. 10. Current certification by the National Ready Mix Concrete Association (NRMCA) for the batch plant(s) to be used in the production of pervious concrete. 11. Current certifications by the NRMCA for the trucks to be used in transporting pervious concrete from the batch plant to the point of placement.
