Designation:D6451/D6451M99(Reapproved 2014)1Standard Guide forApplication of Asphalt Based Protection Board1This standard is issued under the fixed designation D6451/D6451M;the number immediately following the designation indicates theyear of original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1NOTEUnits information was editorially corrected in May 2014.1.Scope1.1 This guide lists minimum application and installationrequirements for semi-rigid protection board when used asprotection for below grade or below wearing surface(like plazadecks)waterproofing.1.2 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.The values stated ineach system may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in non-conformancewith the standard.1.3 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this guide to establish appropriatesafety and health practices and determine the applicability ofregulatory limitations prior to use.For specific precautionarystatement,see Section 8.2.Referenced Documents2.1 ASTM Standards:2D1079 Terminology Relating to Roofing and WaterproofingD5957 Guide for Flood Testing Horizontal WaterproofingInstallations3.Terminology3.1 DefinitionsFor definitions of terms relating towaterproofing,see Terminology D1079.4.Significance and Use4.1 This guide outlines general procedures for the storageand application of semi-rigid protection board to below gradeand below wearing surface waterproofing.The proper applica-tion is necessary to prevent damage to the waterproofingmembrane during backfilling,paving,or other constructionoperations,as well as to minimize the effects of soil stresses.4.2 This guide is intended to supplement instructions fromdesigners and manufacturers.5.Delivery of Materials5.1 Deliver materials in suppliers original containers andpackaging.6.Storage and Handling6.1 Store adhesive and mastic in tightly closed originalcontainers under conditions as recommended by the manufac-turer.6.2 Store the protection board in suppliers original pack-aging in a horizontal position to prevent deformation.Protectagainst exposure to direct sunlight,precipitation,dust,andother such contaminants.7.Materials7.1 Adhesive,when used,must be acceptable to or havebeen recommended by the waterproofing membrane manufac-turer or supplier and further must be fully compatible with themembrane and the asphalt protection board.7.2 Mastic or tape,or both,(if used on the joints)must beacceptable to or have been recommended by the waterproofingmembrane manufacturer or supplier and further be fullycompatible with the membrane and the asphalt protectionboard.8.Safety Precautions8.1 Store flammable materials in a manner that will not posea fire hazard.Solvent bearing adhesives may be flammable.Donot use flammable materials near an open flame or equipmentthat may produce sparks.9.Environmental Conditions at Time of Application9.1 Environmental conditions under which installation mayproceed shall be as recommended by the suppliers of theadhesive and the protection board.1This guide is under the jurisdiction of ASTM Committee D08 on Roofing andWaterproofing and is the direct responsibility of Subcommittee D08.22 on Water-proofing and Dampproofing Systems.Current edition approved May 1,2014.Published May 2014.Originallyapproved in 1999.Last previous edition approved in 2006 as D6451 99(2006).DOI:10.1520/D6451_D6451M-99R14E01.2For 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.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 10.Substrate Preparation10.1 The waterproofing membrane must be clean and suf-ficiently dry so as not to interfere with adhesion of theprotection board.10.2 If a flood test of the membrane is desired,this testshould be made before placing the protection course,inaccordance with Guide D5957.11.Installation11.1 Install protection board within 24 h of completing thewaterproofing membrane installation.Delay installation of theprotection board until the waterproofing film cures.If floodtesting is conducted the application should be as soon aspossible after the surface is dry and clean.11.2 On Low Slope Surfaces:11.2.1 Lay protection board on the membrane in commonbond brick pattern(so that the joints are aligned in onedirection and broken half way over in the other direction)withthe edges butted tightly together.The maximum allowable gapbetween boards is 3 mm 18in.No area of the membraneshall b
