882.2 Materials
882.2.01 Agricultural Lime
A. Requirements Apply agricultural lime made of ground or pelletized dolomitic limestone at the rate recommended by a public or private Soil Laboratory that participates in a national proficiency testing program. Proof of testing is the responsibility of the Contractor. Provide a soil test report to the Engineer prior to application. Take soil test samples in accordance with GSP 18 Sampling Testing and Inspection Specifications. Agricultural lime will meet the following requirements: Requirements Percent by Weight Calcium Carbonates Equivalent, min. 85 Elemental magnesium derived from magnesium carbonate, min. 6 Passing No. 10 (2.00 mm) sieve, min 90 Passing No. 100 (150 µm) sieve, min 25 B. Fabrication General Provisions 101 through 150. C. Acceptance The Department will accept agricultural lime that meets the above requirements. D. Materials Warranty General Provisions 101 through 150.
882.2.02 Lime for Subbase and Sub-Grade Stabilization
A. Requirements Use either a commercial dry hydrated lime or a commercial granular quicklime for soil stabilization. 1. Hydrated Lime: Use hydrated lime that meets the requirements of ASTM C 977, except use lime that has at least 85 percent by weight passing the No. 200 (75 µm) sieve. 2. Quicklime: Use quicklime that meets the requirements of ASTM C 977, except use lime that has 100 percent by weight passing the 3/8-inch (9.5 mm) sieve. If slurry is to be made from slaking quicklime, use quicklime containing at least 94 percent total calcium oxide and magnesium oxide (CaO + MgO), and at least 90 percent total available calcium oxide (CaO). a. Furnish certified test reports with each shipment of lime attesting that the lime meets the requirements of the specification. However, the Engineer may inspect, test, and reject the material at any time. b. Lime from more than one source or more than one type on the same Project may be used, but do not mix lime of different types or from different sources. c. Protect the lime from exposure until used. Ensure that the lime is dry enough to flow freely when handled. B. Fabrication General Provisions 101 through 150. C. Acceptance Test the hydrated and quicklime used for soil stabilization according to ASTM C 977. D. Materials Warranty General Provisions 101 through 150.
882.2.03 Lime for Asphaltic Concrete
A. Requirements Use hydrated lime that meets the chemical and physical properties of AASHTO M 303, Type I. B. Fabrication General Provisions 101 through 150. C. Acceptance 1. Run the chemical analysis of hydrated lime used in asphaltic concrete according to ASTM C 25. 2. Test the physical properties of the hydrated lime according to the residue test in ASTM C 110. NOTE: QPL 41 for lime is used in asphaltic concrete only. 3. See QPL 41 for acceptable hydrated lime that meets the requirements of this specification. D. Materials Warranty General Provisions 101 through 150.
