Standard Practice for the Accelerated Polishing of Aggregates Using the British Wheel

SIGNIFICANCE AND USE
4.1 This practice simulates the polishing action of vehicular traffic on coarse aggregates used in bituminous pavements.  
4.2 A polish value is determined that may be used to rate or classify coarse aggregates for their ability to resist polishing under traffic.
Note 1: The quality of the results produced by this standard are dependant upon the competence of the personnel performing the procedure and the capability, calibration, and the 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 similar acceptable guideline provides a means of evaluating and controlling some of those factors.
SCOPE
1.1 This practice covers a laboratory procedure by which an estimate may be made of the extent to which different coarse aggregates may polish.  
1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. Regarding sieves, per Specification E11: “The values stated in SI units shall be considered standard for the dimensions of the wire cloth openings and the diameter of the wires used in the wire cloth.” When sieve mesh sizes are referenced, the alternate inch-pound designations are provided for information purposes and enclosed in parentheses.

Standard Specification for Color of Retroreflective Pavement Marking Materials

ABSTRACT
This specification covers the daytime and nighttime color of retroreflective pavement marking materials, both painted and tape lines, including thermoplastic, epoxy and other types, used for traffic control lane markings and symbols on road surfaces. This specification is not applicable to the testing, for quality control purposes, of marking material without added drop-on beads. The performance requirements for which the marking materials shall be tested on and conform accordingly to are the daytime and nighttime chromaticity limits, retroreflectance, and daytime lightness limits (Y tristimulus coordinate).
SCOPE
1.1 This specification covers the daytime and nighttime color of retroreflective pavement marking materials used for traffic control lane markings and symbols on road surfaces.  
1.2 This specification applies to all retroreflective pavement markings (markings that include retroreflective optics residing on the surface) except structured pavement markings as defined in 3.2.5.  
1.3 This specification is not applicable to pavement markings that do not include retroreflective optics on the surface.  
1.4 This specification does not address any requirements other than the color of retroreflective pavement markings.  
1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.5.1 Exception—This specification is noted to be an SI document, where angles are generally expressed in radians. However, as angles used in retroreflection have historically been identified in degrees, the International Committee for Weights and Measures (CIPM, Comité International des Poids et Mesures) accepts the use of degrees with SI units, and European Normatives and documents from the International Commission on Illumination (CIE) use degrees for retroreflection geometry.  
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 D3633/D3633M-23(Test Method)
Standard Test Method for Electrical Resistivity of Membrane-Pavement Systems

SIGNIFICANCE AND USE
4.1 This test method for measuring the electrical resistivity of water-barrier membrane-pavement systems may be interpreted to indicate the effectiveness of such systems.  
4.2 This test method is predicated on the fact that an electrical connection between the surface of the pavement and the reinforcing steel in the concrete pavement cannot be made through an impermeable water-barrier membrane.  
4.3 This test method may be used for acceptance when the accepting agency specifies the minimum resistance value desired.  
Note 1: 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 measurement of the electrical resistivity of water-barrier membrane-pavement systems when applied to concrete bridge decks.  
1.2 Measurements shall be performed on the bituminous pavement surface covering the water-barrier membrane.  
1.3 This test method utilizes a measure of electrical resistance between the saturated top surface of the water-barrier membrane and the reinforcing steel embedded in the concrete bridge deck.  
1.4 The values measured represent the electrical resistance obtained with the equipment and procedures stated herein and do not necessarily agree or correlate with those using other equipment or procedures.  
1.5 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.  
1.6 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.  
1.7 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.
