Designation:C127217Standard Specification forHeavy Vehicular Paving Brick1This standard is issued under the fixed designation C1272;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 This specification covers brick intended for use as apaving material in areas with a high volume of heavy vehiculartraffic.The units are designed for use in such places as streets,commercial driveways,and aircraft taxiways.These units arenot intended for applications covered by Specifications C410or C902.1.2 Units are manufactured from clay,shale,or similarnaturally occurring earthy substances and subjected to a heattreatment at elevated temperatures(firing).The heat treatmentmust develop sufficient fired bond between the particulateconstituents to provide the strength and durability requirementsof this specification(see Terminology C1232).1.3 Brick may be shaped during manufacture by extruding,molding,or pressing.Brick may have spacing lugs,chamferededges,or both.1.4 Use of this standard and the requirements herein toevaluate and corroborate the performance of a paving unitmade from other materials,or made with other formingmethods,or other means of binding the materials is not coveredby the scope of this standard.1.5 The values stated in inch-pound units are to be regardedas standard.The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.6 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:2C67 Test Methods for Sampling and Testing Brick andStructural Clay TileC88 Test Method for Soundness of Aggregates by Use ofSodium Sulfate or Magnesium SulfateC410 Specification for Industrial Floor BrickC418 Test Method for Abrasion Resistance of Concrete bySandblastingC902 Specification for Pedestrian and Light Traffic PavingBrickC1232 Terminology of MasonryE303 Test Method for Measuring Surface Frictional Proper-ties Using the British Pendulum Tester3.Terminology3.1 DefinitionsTerms used in this specification are definedin Terminology C1232.3.2 Definitions of Terms Specific to This Standard:3.2.1 heavy vehicular traffchigh volume of heavy ve-hicles representing trucks or combination vehicles having 3 ormore loaded axles.3.2.1.1 DiscussionHigh volume traffic is considered toexceed 251 daily Equivalent Single Axle Loads(ESAL).Defined by the American Association of State Highway Trans-portation Officials(AASHTO),an ESAL converts a mix ofaxle loads on a pavement to an equivalent number of 18,000 lb(80 kN)single axle loads.4.Classification4.1 TypesHeavy vehicular paving brick are classified bytype according to their intended installation:4.1.1 Type RBrick intended to be set in a mortar settingbed supported by an adequate concrete base;or an bituminoussetting bed supported by an adequate asphalt or concrete base.1This specification is under the jurisdiction of ASTM Committee C15 onManufactured Masonry Units and is the direct responsibility of SubcommitteeC15.02 on Brick and Structural Clay Tile.Current edition approved June 1,2017.Published July 2017.Originally approvedin 1995.Last previous edition approved in 2016 as C1272 16b.DOI:10.1520/C1272-17.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1 4.1.2 Type FBrick intended to be set in an aggregatesetting bed,with aggregate joints,and supported by an ad-equate base.4.2 ApplicationsHeavy vehicular paving brick are classi-fied by application according to their dimensional tolerances,warpage,and extent of chips.4.2.1 Application PSPavers intended for general use.4.2.2 Application PXPavers intended for use where ahigher degree of precision and a lower permissible variation indimensional tolerances and warpage are required than forApplication PS.4.2.3 Application PAPavers intended to produce charac-t
