Designation:C90215Standard Specification forPedestrian and Light Traffic Paving Brick1This standard is issued under the fixed designation C902;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 aspaving material subjected to pedestrian and light vehiculartraffic.The units are designed for use in pedestrian applicationsand vehicular areas that are subjected to low volumes ofvehicular traffic,such as residential driveways and streets andcommercial driveways(passenger drop-offs).The units are notintended to support heavy vehicular traffic covered by Speci-fication C1272 or for industrial applications covered by Speci-fication C410.NOTE1Heavy vehicular traffic is defined as high volumes of heavyvehicles(trucks having 3 or more axles)in Specification C1272.1.2 The property requirements of this specification apply atthe time of purchase.The use of results from testing of brickextracted from masonry structures for determining confor-mance or nonconformance to the property requirements(Sec-tion 5)of this specification is beyond the scope of thisspecification.1.3 Brick 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 requirementof this specification(see Terminology C1232).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 brick are available in a variety of sizes,colors,andshapes.They are available in three classes according toexposure environment and three types according to type oftraffic exposure.1.6 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.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 bySandblastingC1232 Terminology of MasonryC1272 Specification for Heavy Vehicular Paving Brick3.Terminology3.1 DefinitionsFor definitions relating to paving brick,refer to Terminology C1232.4.Classification4.1 Light traffic paving brick are classified according to theseverity of their use-environment.Two types of environmentare considered:(1)weather and(2)traffic:4.1.1 WeatherWeathering resistance is specified by one ofthree classes.When the class is not specified,the requirementsfor Class SX shall govern.4.1.1.1 Class SXBrick intended for use where the brickmay be frozen while saturated with water.4.1.1.2 Class MXBrick intended for exterior use whereresistance to freezing is not a factor.4.1.1.3 Class NXBrick not intended for exterior use butwhich may be acceptable for interior use where protected fromfreezing when wet.NOTE2A surface coating may be applied to any class of brick of thisstandard when protected from freezing while wet.The function of thecoating is to prevent penetration of dirt or liquids into the pores of thebrick.Coatings should be applied only after complete drying of thepaving.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 Dec.1,2015.Published January 2016.Originallyapproved in 1979.Last previous edition approved in 2014 as C902 14.DOI:10.1520/C0902-15.2For 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 States1 4.1.2 TraffcAbrasion resistance is specified by one ofthree types.When the type is not specified,the requirementsfor Type II govern.4.1.2.1 Type IBrick subjected to extensive abrasion.NOTE3Type I pavers would be used in such places as sidewalks anddriveways in publicly occupied spaces.4.1.2.2 Type IIBrick subjected to intermediate abrasion.NOTE4Type II pavers would be used in such places as heavilytraveled residential walkways and residential driveways.4.1.2.3 T
