5.1 Knowledge of the boiling point distribution of stabilized crude oils is important for the marketing, scheduling, and processing of crude oil in the petroleum industry. Test Method D7169 and IP 545 purport to give such a distribution in crude oils, but are susceptible to significant errors in the light ends portion of the distribution as well as in the mass recovery of the whole crude oil due to the interference imposed by the diluent solvent. This test method allows for more accurate determination of the front end of the boiling point distribution curve, in addition to providing important C1 to C9 (nonane) component level information, and more accurate mass recovery at C9 (nonane).1.1 This test method specifies a method to determine the boiling range distribution of hydrocarbons in stabilized crude oil up to and including n-nonane. A stabilized crude oil is defined as having a Reid Vapor Pressure equivalent to or less than 82.7 kPa. The results of this test method can be combined with those from Test Method D7169 and IP 545 to give a full boiling point distribution of a crude oil (see Appendix X3).1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided for information purposes only.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This specification establishes the material and manufacturing requirements for water-based asphalt emulsion (mineral colloid or chemically stabilized type) pavement sealers suitable for use as a weather-protective coating over bituminous pavements, such as roadways, driveways, and parking areas. The base asphalt emulsion shall be made using binders prepared from crude petroleum; the mineral filler (when used), shall consist of finely ground clay, silica, limestone, slate, basalt, slag, or other inert inorganic filler materials; and the aggregate shall be either a natural or manufactured angular aggregate composed of clean, hard, durable particles free of clay or other objectionable material. The aggregate to be used shall follow the manufacturer's recommendations; however, 100% of the aggregate shall pass a 2.38 mm [No. 8] mesh-sieve at all times. Aggregate may either be added at the point of manufacture, post-added at the job site, or both. The use of an additive is optional and shall be approved by the asphalt emulsion pavement sealer manufacturer.This specification also covers the physical requirements, sampling, inspection, and packaging and package marking for asphalt emulsion pavement sealers (mineral colloid or chemically stabilized type).1.1 This specification covers water-based asphalt emulsion (mineral colloid or chemically stabilized type) pavement sealer suitable for use as a weather-protective coating over bituminous pavements, such as roadways, parking areas, and driveways.NOTE 1: Application shall be made in accordance with a forthcoming ASTM standard on the application of asphalt emulsion pavement sealer.1.2 The values stated in SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

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. Typical curing time intervals are 7, 28, 60, or 90 days or combinations thereof after placement. Twenty-eight (28) days after placement is the most common time interval for first drilling cores.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/etc. 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 This guide covers obtaining cores of soil-cement or lime-stabilized soil for use in determining compressive strength, lift thickness and bond strength, and other physical properties. This guide is primarily for use in coring through shallow (0.3 to 3 m (1 to 10 ft) thick) layers of cement or lime-stabilized soils containing particles < 50 mm (2 in.) in diameter to the underlying foundation.Note 1—This guide could be used for some Class C self-cementing fly ash materials, which may also stabilize soil.1.2 This guide does not cover material of less than 2100 kPa (300 psi) compressive strength such as cement-soil-bentonite mixtures or some controlled low strength materials (CLSM).1.3 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026.1.4 The values stated in SI units are to be regarded as the standard. Other values are examples or for information only.1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in Section 8.1.6 This guide offers an organized collection of information or a series of options and does not recommend a specific course of action. This guide cannot replace education or experience and should be used in conjunction with professional judgment. Not all aspects of this guide may be applicable in all circumstances. This guide is not intended to represent or replace the standard of care by which the adequacy of a given professional service must be judged, nor should this guide be applied without consideration of a project's many unique aspects. The word “Standard” in the title of this document means only that the document has been approved through the ASTM consensus process.1.7 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.
