760 Page 507760 HYDRATED LIME

Hydrated calcium or dolomitic lime will consist of a dry powder obtained by treating quicklime with enough water to satisfy the chemical affinity for water under the conditions of hydration. Hydrated lime will meet the following requirements: Calcium and Magnesium Oxide (nonvolatile basis) Minimum %......................................................................... 93* * Determined on ignited sample Carbon Dioxide, as received basis, Free Water or Mechanical Moisture as received basis, Maximum % if sampled at place of manufacture .............................................. 1.0 Maximum % if sampled at any other place ................................................................. 1.5 The maximum percent by weight of residue retained will conform to the following requirements: Sieve SizeMaximum Percent Retained #30 3.0 #200 20.0 Hydrated lime will be sampled according to SD 502. The chemical and physical properties listed above will be tested based on the intended use of the hydrated lime in accordance with the following: Hydrated Lime for Soil Stabilization: .................................................. ASSHTO M 216 Hydrated Lime for Asphalt Mixtures: .................................................. ASSHTO M 303 Lime will be stored and handled in closed weatherproof containers until immediately before distribution on the project. When storage bins are used, they will be completely enclosed. Lime furnished in bags will be stored in weatherproof buildings with protection from ground dampness. When lime is furnished in trucks, the Contractor will have the weight of each truck of lime certified on a public scale or the Contractor will provide a set of standard platform truck scales or hopper scales approved by the Engineer. When lime is furnished in bags, each bag will designate the weight, type of material, and name of manufacturer. Bags varying more than 5% from the certified weight may be rejected. The average weight of bags in any shipment, as shown by weighing 50 bags taken at random, will not be less than the manufacturer's certified weight. 770 Page 508770 CALCIUM CHLORIDE 770 CALCIUM CHLORIDE Calcium chloride will conform to AASHTO M 144.
