Types NA and SA are air-entrained hydrated limes that are suitable for use in any of the above uses where the inherent properties of lime and air-entrainment are desired. The four types of lime under this specification shall be designated as Type N which is the normal hydrated lime for masonry purposes, type S which is the special hydrated lime for masonry purposes, type NA which is the normal air-entraining hydrated lime for masonry purposes and type SA which is the special air-entraining hydrated lime for masonry purposes. Hydrated lime for masonry purposes shall conform to the required chemical composition for calcium and magnesium oxides and carbon dioxide. The hydrated lime covered by Types N or S in this specification shall contain no additives for the purpose of entraining air.1.1 This specification covers four types of hydrated lime.

Coring is performed to evaluate construction control and physical properties of stabilized soil.Coring is conducted to determine the quality and the total thickness of the stabilized soil and to evaluate bonding between lifts.Coring stabilized soil before it has cured to at least 2100 kPa (300 psi) compressive strength can cause excessive breakage in the core.If lab-cured specimens are prepared, samples may be cored to correlate with specified break intervals of the lab-cured specimens.

4.1 These test methods provide accurate and reliable analytical procedures to determine the chemical constituents of limestone, quicklime, and hydrated lime (see Note 1). The percentages of specific constituents which determine a material's quality or fitness for use are of significance depending upon the purpose or end use of the material. Results obtained may be used in relation to specification requirements.4.2 Because quicklime and hydrated lime quickly absorb water and carbon dioxide from the air, precision and bias are extremely dependent upon precautions taken during sample preparation and analysis to minimize excessive exposure to ambient conditions.NOTE 1: These test methods can be applied to other calcareous materials if provisions are made to compensate for known interferences.1.1 These test methods cover the chemical analysis of high-calcium and dolomitic limestone, quicklime, and hydrated lime. These test methods are classified as either standard (preferred) or alternative (optional).1.2 The standard test methods are those that employ classical gravimetric or volumetric analytical procedures and are typically those required for referee analyses where chemical specification requirements are an essential part of contractual agreement between buyer and seller.1.3 Alternative or optional test methods are provided for those who wish to use procedures shorter or more convenient than the standard methods for the routine determinations of certain constituents. Optional test methods may sometimes be preferred to the standard test methods, but frequently the use of modern and expensive instrumentation is indicated which may not be accessible to everyone. Therefore, the use of these test methods must be left to the discretion of each laboratory.1.4 The analytical procedures appear in the following order:  Section     Aluminum Oxide  15     Available Lime Index  28     Calcium and Magnesium Oxide:      Alternative EDTA Titration Method  31     Calcium Carbonate Equivalent  33     Calcium Oxide:      Gravimetric Method  16      Volumetric Method  17     Carbon Dioxide by Standard Method  22     Combined Oxides of Iron and Aluminum  12     Ferrous Iron  Appendix X5     Free Calcium Oxide  Appendix X6     Free Moisture in Hydrated Lime  21     Free Moisture in Limestone  20     Free Silica  29     Insoluble Matter Including Silicon Dioxide:      Standard Method   8      Optional Perchloric Acid Method   9     Insoluble Matter Other Than Silicon Dioxide  11     Loss on Ignition  19     Magnesium Oxide  18     Manganese:      Bismuthate Method  Appendix X4      Periodate (Photometric) Method  27     pH Determination of Alkaline Earth Solutions  34     Phosphorus:      Titrimetric Method  Appendix X3      Molybdovanadate Method  26     Silicon Dioxide  10     Strontium Oxide  Appendix X2     Sulfur Trioxide  23     Total Carbon:      Direct Combustion-Thermal Conductivity Cell      Method 32     Total Carbon and Sulfur:      Combustion/Infrared Detection Method  35     Total Iron:      Standard Method, Potassium Dichromate      Titration  13      Potassium Permanganate Titration Method  Appendix X1      Ortho-Phenanthroline, Photometric Method  14     Total Sulfur:      Sodium Carbonate Fusion  24      Combustion-Iodate Titration Method  25      Unhydrated Oxides  301.5 This standard does not purport to address all of the safety concerns, if any, associated with its use.

From these tests the relative expansive potential of soil-lime mixtures containing varying amounts of lime can be evaluated. From such an evaluation, the amount of lime required to reduce expansion to acceptable levels can be determined. The data can then be used for the design and specification requirements for subgrades and structural fills where expansive soils are encountered and it is desired to give a certain degree of expansion-shrinkage control to structure foundations and road subgrades. The tests will also show if the specific soils are amenable to lime stabilization.Note 2—The quality of the result produced by this standard is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used. Agencies that meet the criteria of Practice D3740 are generally considered capable of competent and objective testing/sampling/inspection/and the like. Users of this standard are cautioned that compliance with Practice D3740 does not in itself assure reliable results. Reliable results depend on many factors; Practice D3740 provides a means of evaluating some of those factors.1.1 These test methods provide procedures for conducting expansion, shrinkage, and uplift pressure tests on compacted soil-lime mixtures and can be used to determine the lime content required to achieve desired control of volume changes caused by increases or decreases of moisture.1.2 The tests can be used to determine (a) the magnitude of volume changes under varying load conditions, (b) the rate of volume change, and (c) the magnitude of pressure change as moisture changes of the soil-lime mixture take place. The permeability of soil-lime mixture can also, if desired, be determined at the various load conditions.Note 1—Changes in field conditions can have major effects on the expansion and shrinkage characteristics of expansive soils. Therefore, to the greatest extent possible, initial and anticipated future field conditions should be duplicated, particularly with respect to moisture and density.1.3 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026, D37401.3.1 The method used to specify how data are collected, calculated, or recorded in this standard is not directly related to the accuracy to which the data can be applied in design or other uses, or both. How one applies the results obtained using this standard is beyond its scope.1.4 The values stated in SI units are to be regarded as the standard.
