ASTM D8125-18(2023)(Specification)
Standard Specification for Re-Refined Engine Oil Bottoms (REOB)/Vacuum Tower Asphalt Extender (VTAE)

ABSTRACT
This specification establishes the material, manufacturing, and physical requirements for re-refined engine oil bottoms, also known as vacuum tower asphalt extender, that may be used in formulating asphalt for pavement construction and roofing. "Re-refined engine oil bottoms" (REOB) is the commonly used term used by many state highway agencies and FHWA, while "vacuum tower asphalt extender" (VTAE) is preferred by manufacturers. REOB/VTAE may be obtained by processing used engine oil using atmospheric distillation followed by vacuum distillation to produce a vacuum residuum meeting the requirements outlined in this specification. The REOB/VTAE shall be homogenous, free from water, and not foam when heated to 232°C (450°F).
SCOPE
1.1 This specification covers re-refined engine oil bottoms, also known as vacuum tower asphalt extender, that may be used in formulating asphalt for pavement construction and roofing. This specification has been developed specifically for these two categories of product and is not intended for other uses. Table 1 is to be used for pavement construction and Table 2 for roofing. “Re-refined engine oil bottoms” (REOB) is the prevailing name used by many state highway agencies and FHWA, while “vacuum tower asphalt extender” (VTAE) is the preferred name used by the manufacturers of the product. Since each name provides an important descriptor of production elements (“re-refined” and “vacuum tower”) for the specific product this specification addresses, this specification uses the term “REOB/VTAE.”  
1.2 Units—The values stated in either 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.

1.1 This guide covers the physical and chemical requirements of virgin or recovered foundry sand for use as a fine aggregate in asphalt mixtures.  
1.2 This guide is for use by contractors, foundry sand suppliers, or other purchasers as part of the purchase document describing the material to be furnished. Those responsible for selecting the proportions for the asphalt mixture should have the responsibility of determining the proportions of foundry sand as a fine aggregate.  
1.3 The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard.  
1.4 The text of this standard references notes and footnotes which provide explanatory information. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of this standard.  
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

Standard Test Method for Thickness or Height of Compacted Asphalt Mixture Specimens

SIGNIFICANCE AND USE
4.1 The thickness of a compacted asphalt mixture is often used as a construction check to ensure that the proper quantity of materials has been placed on a project, and to correct strength measurement on constant diameter specimens with varying heights.
Note 1: The text of this test method 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 test method.
Note 2: The quality of the results produced by this standard are dependent on the competence of the personnel performing the procedure and the capability, calibration, and maintenance of the equipment used. Agencies that meet the criteria of Specification D3666 are generally considered capable of competent and objective testing, sampling, inspection, etc. Users of this standard are cautioned that compliance with Specification D3666 alone does not completely ensure reliable results. Reliable results depend on many factors; following the suggestions of Specification D3666 or some similar acceptable guideline provides a means of evaluating and controlling some of those factors.
SCOPE
1.1 This test method covers determination of the thickness (or height) of compacted asphalt mixture specimens.  
1.2 Units—The values stated in either 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.  
1.2.1 Section 7.4 specifies SI units because they are the units used in the equations for Test Methods D1188/D1188M and D2726/D2726M. Performing calculations without first converting any measurements made in inch-pound units to SI units in 7.4 will 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.

Standard Test Method for Determination of Density and Relative Density of Asphalt, Semi-Solid Bituminous Materials, and Soft-Tar Pitch by Use of a Digital Density Meter (U-Tube)

SIGNIFICANCE AND USE
5.1 Values of density are used for converting volumes to units of mass and for correcting measured volumes at the measured temperature to a standard temperature using Practice D4311/D4311M.
Note 2: The quality of the results produced by this standard are dependent on the competence of the personnel performing the procedure and the capability, calibration, and maintenance of the equipment used. Agencies that meet the criteria of Specification D3666 are generally considered capable of competent and objective testing, sampling, inspection, etc. Users of this standard are cautioned that compliance with Specification D3666 alone does not completely ensure reliable results. Reliable results depend on many factors; following the suggestions of Specification D3666 or some similar acceptable guideline provides a means of evaluating and controlling some of those factors.
SCOPE
1.1 This test method covers the determination of the relative density and density of semi-solid asphalt materials, asphalt binders, asphalt cements, and soft-tar pitches by use of a digital density meter (U-tube).
Note 1: Alternate methods for determining the density of semi-solid and solid asphalt materials and asphalt binders include Test Methods D3289, D3142/D3142M, and D70/D70M.  
1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only. No other units of measurement are included in this standard, with the exception of temperature measurements. Units provided in degrees Fahrenheit are for reference purposes only. Temperatures given in degrees Celsius are to be considered standard.  
1.3 This test method should not be applied to petroleum distillates other than asphalt and asphalt binders. For the determination of density of all other petroleum distillates and viscous oils, use Test Method D4052 or D5002, or ISO 12185.  
1.4 The text of this standard references notes and footnotes which provide explanatory material. These footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.  
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.6 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.

ASTM D2170/D2170M-22(Test Method)
Standard Test Method for Kinematic Viscosity of Asphalts

SIGNIFICANCE AND USE
5.1 The kinematic viscosity characterizes flow behavior. The method is used to determine the consistency of liquid asphalt as one element in establishing the uniformity of shipments or sources of supply. The specifications are usually at temperatures of 60 and 135 °C.
Note 3: The quality of the results produced by this standard are dependent on the competence of the personnel performing the procedure and the capability, calibration, and maintenance of the equipment used. Agencies that meet the criteria of Specification D3666 are generally considered capable of competent and objective testing, sampling, inspection, etc. Users of this standard are cautioned that compliance with Specification D3666 alone does not completely ensure reliable results. Reliable results depend on many factors; following the suggestions of Specification D3666 or some similar acceptable guideline provides a means of evaluating and controlling some of those factors.
SCOPE
1.1 This test method covers procedures for the determination of kinematic viscosity of liquid asphalts, road oils, and distillation residues of liquid asphalts all at 60 °C [140 °F] and of liquid asphalt binders at 135 °C [275 °F] (see table notes, 11.1) in the range from 6 to 100 000 mm2/s [cSt].  
1.2 Results of this test method can be used to calculate viscosity when the density of the test material at the test temperature is known or can be determined. See Annex A1 for the method of calculation.  
Note 1: This test method is suitable for use at other temperatures and at lower kinematic viscosities, but the precision is based on determinations on liquid asphalts and road oils at 60 °C [140 °F] and on asphalt binders at 135 °C [275 °F] only in the viscosity range from 30 to 6000 mm2/s [cSt].
Note 2: Modified asphalt binders or asphalt binders that have been conditioned or recovered are typically non-Newtonian under the conditions of this test. The viscosity determined from this method is under the assumption that asphalt binders behave as Newtonian fluids under the conditions of this test. When the flow is non-Newtonian in a capillary tube, the shear rate determined by this method may be invalid. The presence of non-Newtonian behavior for the test conditions can be verified by measuring the viscosity with viscometers having different-sized capillary tubes. The defined precision limits in 11.1 may not be applicable to non-Newtonian asphalt binders.  
1.3 Warning—Mercury has been designated by the United States Environmental Protection Agency (EPA) and many state agencies as a hazardous material that can cause central nervous system, kidney, and liver damage. Mercury, or its vapor, may be hazardous to health and corrosive to materials. Caution should be taken when handling mercury and mercury-containing products. See the applicable product Material Safety Data Sheet (MSDS) or Safety Data Sheet (SDS) for details and the EPA’s website—http://www.epa.gov/mercury/faq.htm—for additional information. Users should be aware that selling mercury, mercury-containing products, or both, in your state may be prohibited by state law.  
1.4 The values stated in either 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.  
1.5 The text of this standard references notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.
