Designation:B864/B864M13Standard Specification forCorrugated Aluminum Box Culverts1This standard is issued under the fixed designation B864/B864M;the number immediately following the designation indicates the yearof original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 This specification covers material,geometric,and wallsection properties of aluminum box culverts manufacturedfrom corrugated plate or sheet,with attached rib stiffeners,forfield assembly.Appropriate fasteners and optional materials,such as aluminum invert plates and headwalls,are alsodescribed.Applications for aluminum box culverts includeconduits for gravity flow drainage of surface water,such asculverts and storm drains,as well as for small bridges andgrade separation structures such as pedestrian or vehicularunderpasses,and utility tunnels.1.2 This specification does not include requirements forfoundations,backfill,or the relationship between earth cover orlive loads and strength requirements.These important designconsiderationsaredescribedintheAASHTOLRFD Bridge Design Specifications and the LRFD BridgeConstruction Specifications.1.3 This specification does not include requirements for thehydraulic design of these structures.Hydraulic design,place-ment of footings or inverts,and end treatments to resist scourare described in FHWA HDS No.5.1.4 Appendix X1 lists nominal dimensions of box culvertsizes commonly available.Also listed are cross-sectional areaand hydraulic design parameters for these sizes.1.5 Appendix X2 lists manufacturers suggested designproperties for the rib stiffener types,spacing classes,andmaterial thicknesses described in this specification.1.6 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.2.Referenced Documents2.1 ASTM Standards:2A36/A36M Specification for Carbon Structural SteelA123/A123M Specification for Zinc(Hot-Dip Galvanized)Coatings on Iron and Steel ProductsA153/A153M Specification for Zinc Coating(Hot-Dip)onIron and Steel HardwareA307 Specification for Carbon Steel Bolts,Studs,andThreaded Rod 60 000 PSI Tensile StrengthA563 Specification for Carbon and Alloy Steel NutsA563M Specification for Carbon andAlloy Steel Nuts(Met-ric)B221 Specification for Aluminum and Aluminum-Alloy Ex-truded Bars,Rods,Wire,Profiles,and TubesB746/B746M Specification for Corrugated Aluminum AlloyStructural Plate for Field-Bolted Pipe,Pipe-Arches,andArchesB790/B790M Practice for Structural Design of CorrugatedAluminum Pipe,Pipe-Arches,and Arches for Culverts,Storm Sewers,and Other Buried Conduits2.2 AASHTO Standard:LRFD Bridge Design Specifications3LRFD Bridge Construction Specifications2.3 FHWA Standard:HDS No.5,Hydraulic Design of Highway Culverts,ThirdEdition.FHWA publication number HIF1202(2012).43.Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 box culverta generally rectangular conduit having across section symmetric about a vertical axis,with a longradius crown segment,short radius haunch segments,andstraight side segments,with rib stiffeners(see Fig.1).3.1.2 crownthe long radius top arc segment of a boxculvert cross section(see Fig.1).1This specification is under the jurisdiction of ASTM Committee B07 on LightMetals and Alloys and is under the direct responsibility of B07.08 on CorrugatedAluminum Pipe and Corrugated Aluminum Structural Plate.Current edition approved May 1,2013.Published June 2013.Originallyapproved in 1995.Last previous edition approved in 2008 as B864/B864M-08.DOI:10.1520/B0864_B0864M-13.2For 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.3Available from American Association of State Highway and TransportationOfficials(AASHTO),444 N.Capitol St.,NW,Suite 249,Washington,DC 20001,http:/www.transportation.org.4Available from National Technical Information Service(NTIS),5285 PortRoyal Rd.,Springfield,VA 22161,http:/www.ntis.gov.*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 3.1.3 haunchthe short radius segments at the upper cor-ners of a box culvert cross section,making the transitionbetween the long radius crown segment and the straight sidesegments(see Fig.1).3.1.4 rib stiffenersspaced extruded aluminum structuralmembers,curved to the shape of the transverse cross section ofbox culverts and attached by field-bolting to the corrugatedplate shell(see Fig.1).3.
