Standard Specification for Solid Concrete Interlocking Paving Units

Standard Specification for Solid Concrete Interlocking Paving Units

ABSTRACT
This specification is intended for interlocking concrete pavers used in the construction of paved surfaces and manufactured from cementitious materials, aggregates, chemical admixtures, and other constituents such as integral water repellents. The specification also offers guidelines for physical requirements, sampling and testing, visual inspection, and rejection of specimens.
SCOPE
1.1 This specification covers the requirements for interlocking concrete pavers manufactured for the construction of paved surfaces.  
1.2 Concrete units covered by this specification shall be made with lightweight or normal weight aggregates or both.
Note 1: If particular features are desired, such as weight classification, higher compressive strength, surface textures, finish, color, or other special features, such properties should be specified by the purchaser. Local sellers, however, should be consulted as to availability of units having the desired features.  
1.3 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 non-conformance with the standard.  
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.

ASTM C1272-22a(Specification)
Standard Specification for Heavy Vehicular Paving Brick

ABSTRACT
This specification covers heavy vehicular paving bricks designed for use in streets, commercial driveways, aircraft taxiways, and other places where there is a high volume of heavy vehicular traffic. The bricks should be manufactured from clay, shale, or similar naturally occurring earthy substances and subjected to firing. The high temperature heat treatment should develop sufficient fired bonds between the material particles to produce the required strength and durability. The bricks may also be shaped by extruding, molding, or pressing during manufacture and may have spacing lugs, chamfered edges, or both. The materials are classified into two types according to the intended installation and should all conform to the required values of freeze thaw resistance, abrasion resistance, skid resistance, coring, chips or cracks, and efflorescence.
SCOPE
1.1 This specification covers brick intended for use as a paving material in areas with a high volume of heavy vehicular traffic. The units are designed for use in such places as streets, commercial driveways, and aircraft taxiways. These units are not intended for applications covered by Specifications C410 or C902.  
1.2 The requirements of this specification apply at the time of purchase. The use of results from testing of brick extracted from pavements for determining compliance with the requirements of this specification is beyond the intent of this standard.  
1.3 Units are manufactured from clay, shale, or similar naturally occurring earthy substances and subjected to a heat treatment at elevated temperatures (firing). The heat treatment must develop sufficient fired bond between the particulate constituents to provide the strength and durability requirements of this specification (see Terminology C1232).  
1.4 Brick may be shaped during manufacture by extruding, molding, or pressing. Brick may have spacing lugs, chamfered edges, or both.  
1.5 Use of this standard and the requirements herein to evaluate and corroborate the performance of a paving unit made from other materials, or made with other forming methods, or other means of binding the materials is not covered by the scope of this standard.  
1.6 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.7 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 C1781/C1781M-21(Test Method)
Standard Test Method for Surface Infiltration Rate of Permeable Unit Pavement Systems

SIGNIFICANCE AND USE
5.1 This test method can be used for acceptance of surface infiltration of new permeable unit pavement systems.  
5.2 Tests performed at the same location across a span of years may be used to detect a reduction of infiltration rate of the permeable surface, thereby identifying the need for any remedial maintenance intended to increase the infiltration rates to predefined levels.  
5.3 The infiltration rate obtained by this method is valid only for the localized area of the pavement where the test is conducted. To determine the surface infiltration rate of the entire permeable pavement, multiple locations must be tested and the results averaged.  
5.4 The minimum acceptable infiltration rate is typically established by the design engineer of record or the municipality and can be a function of the design precipitation event.  
5.5 This test method can also be used to demonstrate the infiltration rate of a particular permeable unit pavement system if the drainage joints are filled with the aggregate that is specified for use in that system.
SCOPE
1.1 This test method covers the determination of the field surface infiltration rate of in place permeable unit pavement systems surfaced with solid interlocking concrete paving units, concrete grid paving units, or clay paving brick.
Note 1: For in-place pervious concrete, Test Method C1701/C1701M should be used. Test Method C1701/C1701M is functionally identical to this standard, but does not include the added provisions for positioning and securing the test ring to a discontinuous surface, which are detailed in this standard. Both tests methods give comparable results  
1.2 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 non-conformance with the standard.  
1.3 The text of this test method references notes that provide explanatory material. These notes shall not be considered as requirements of the test method.  
1.4 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.  
1.5 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 Practice for Sampling Asphalt Materials

SIGNIFICANCE AND USE
4.1 Sampling is as important as testing, and precautions shall be taken to obtain samples to show the true nature and condition of the materials.  
4.2 Samples are taken for either of the following two purposes:  
4.2.1 To represent as nearly as possible an average of the bulk of the materials sampled, or  
4.2.2 To ascertain the maximum variation in characteristics which the material possesses.
SCOPE
1.1 This practice applies to the sampling of asphalt materials at points of manufacture, storage, or delivery.  
1.2 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.

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.  
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 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.

Standard Practice for Preparation of Compacted Slab Asphalt Mix Samples Using a Segmented Rolling Compactor

SIGNIFICANCE AND USE
5.1 Asphalt slabs compacted with the rolling compactor can be used to obtain specimens for further testing, including bulk specific gravity following Test Methods D1188/D1188M, D2726/D2726M, and D6752/D6752M, fatigue performance characteristics following Test Methods D7460 and D8237 or AASHTO T 321, and Hamburg wheel-track testing following AASHTO T 324.  
5.2 Specimens to perform other standard tests could also be obtained, as long as their volume is contained within the volume of a slab.
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 practice 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 that provides a means of evaluating and controlling some of those factors.
SCOPE
1.1 This practice covers the fabrication of slabs of asphalt mix using an automated laboratory rolling compactor (RC). Compacted specimens are suitable for volumetric and physical property testing. This practice should not be used for acceptance or rejection of a material or for purchasing purposes.  
1.2 Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.3 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.
