ALUMINUM BOX CULVERT CONCEPT

NOT TO SCALE

ALUMINUM BOX CULVERTS (ALBC):

1. ALBCS WILL BE INSTALLED AT CROSSINGS 3 & 5.

2. MATERIAL: THE ALUMINUM BOX CULVERT SHALL CONSIST OF PLATES, RIBS, AND APPURTENANT ITEMS AS SHOWN ON THE PLANS AND SHALL

CONFORM TO THE REQUIREMENTS OF ASTM B 864.

2.1. PLATE THICKNESS, RIB SPACINGS, AND TYPE OF INVERT AND FOUNDATION SHALL BE AS INDICATED ON SHEET 22, DRAWING 929-02.

2.2. ALL MANUFACTURING PROCESSES INCLUDING CORRUGATING, PUNCHING, CURVING AND GALVANIZING SHALL BE PERFORMED WITHIN THE

UNITED STATES USING RAW MATERIALS MADE IN THE UNITED STATES.

2.3. BOLTS AND NUTS SHALL CONFORM TO THE REQUIREMENTS OF ASTM A307 OR ASTM A449.

3. ASSEMBLY: THE BOX CULVERT SHALL BE ASSEMBLED IN ACCORDANCE WITH THE SHOP DRAWINGS PROVIDED BY THE MANUFACTURER AND PER THE

MANUFACTURER'S RECOMMENDATIONS. BOLTS SHALL BE TIGHTENED USING AN APPLIED TORQUE OF BETWEEN 100 AND 150 FT.-LBS.

4. INSTALLATION: THE BOX CULVERT SHALL BE INSTALLED IN ACCORDANCE WITH THE PLANS AND SPECIFICATIONS, THE MANUFACTURER'S

RECOMMENDATIONS, AND THE AASHTO STANDARD SPECIFICATION FOR HIGHWAY BRIDGES, SECTION 26 (DIVISION II).

5. BEDDING: THE BEDDING SHOULD BE CONSTRUCTED TO A UNIFORM LINE AND GRADE USING MATERIAL OUTLINED IN THE BACKFILL SECTION.

6. BACKFILL: THE STRUCTURE SHALL BE BACKFILLED USING CLEAN WELL GRADED GRANULAR MATERIAL THAT MEETS THE REQUIREMENTS OF

AASHTO M 145 FOR SOIL CLASSIFICATIONS A-1, A-3, A-2-4, OR A-2-5. BACKFILL MUST BE PLACED SYMMETRICALLY ON EACH SIDE OF THE STRUCTURE

IN 6 TO 8 INCH LIFTS. EACH LIFT SHALL BE COMPACTED UNTIL THERE IS NO VISIBLE DISPLACEMENT. IF MANUFACTURER RECOMMENDATIONS FOR

BACKFILL DIFFER FROM THIS, THE MANUFACTURER'S RECOMMENDATIONS SHALL BE FOLLOWED. IF MORE LENIENT GRADATION IS ACCEPTABLE TO

THE MANUFACTURER (DUE TO LIGHT LOADING), PIT RUN OR NATIVE 2" MINUS WOULD BE ACCEPTABLE TO THE GOVERNMENT. THESE REQUIREMENTS

ARE FOR THE FILL IMMEDIATELY AROUND THE ALBC. REMAINING AREA CAN BE BACKFILLED WITH NATIVE SOIL OR PIT RUN MATERIAL. THE TOP 6" OF

TRAIL SURFACE MUST BE D-1 MATERIAL.

7. LIVE LOAD TRAFFIC IS NOT ALLOWED ON THE STRUCTURE UNTIL THE STRUCTURE HAS BEEN BACKFILLED.

8. STRUCTURES AS SHOWN ON THESE PLANS ARE DESIGNED TO H-20 LOADING. THE CONTRACTOR SHALL WORK WITH THE MANUFACTURER TO

FABRICATE STRUCTURES TO H-5 (OR PEDESTRIAN TRAIL) LOADING AS A COST SAVINGS.

ROCK HEADWALLS:

9. RETAINER ROCKS SHALL BE A MINIMUM OF 50 LBS AND LARGE ENOUGH TO CONTAIN THE FILL, APPROXIMATELY 10-12" AT A MINIMUM.

10. REMOVE AND DISPOSE OF DUFF AND TOP ORGANIC LAYERS DOWN TO MINERAL SOIL.

11. LAY ROCK WITH A MINIMUM OF 3 POINTS OF CONTACT WITH ADJACENT ROCKS.

12. LAY ROCKS IN A RANDOM ARRANGEMENT.

13. FILL VOIDS WITH BROKEN ROCK OR SUITABLE BACKFILL.

14. ALBC SHALL HAVE A TYPE IV (SHEET 22, DRAWING 929-02) REINFORCING RIB AROUND THE FACE OF THE STRUCTURE TO HELP CONTAIN THE RETAINER

ROCKS. SEE CROSSING-SPECIFIC SHEETS FOR A DEPICTION OF THE RIB-ROCK JUNCTION.

15. THE CONTRACTOR MAY SUBMIT COST SAVING ALTERNATIVES, SUCH AS USE OF TREATED TIMBER FOR THE RETAINER OVER THE CULVERT. APPROVAL

IS NOT GUARANTEED BUT ALL OPTIONS WILL BE CONSIDERED.

MANUFACTURER TO ACHIEVE REQUIRED VERTICAL CAPACITY FOR THE LOADING DESCRIBED IN NOTE 9.

6. MANUFACTURER: AN ACCEPTABLE PRODUCT LINE IS THE CHANCE TYPE RS2875.203, MANUFACTURED BY HUBBELL POWER SYSTEMS, INC. OTHER

PRODUCTS MAY BE ACCEPTABLE IF THEY MEET ALL REQUIREMENTS OUTLINED IN THE DRAWINGS, SPECIFICATIONS, AND SOW.

7. MATERIAL - ALL SHALL BE HOT DIP GALVANIZED PER ASTM A153 CLASS B-1:

7.1. SHAFT - HSS 2-7/8 INCH OD X 0.203 INCH (SCHEDULE 40) WALL STEEL.

7.2. COUPLING - FORGED AS AN INTEGRAL PART OF THE PLAIN AND HELICAL EXTENSION MATERIAL AS ROUND DEEP SOCKETS CONNECTED WITH

MULTIPLE STRUCTURAL BOLTS.

7.3. HELIX - 3/8 INCH THICK: ASTM A572, OR A 1018, OR A656 WITH MINIMUM YIELD STRENGTH OF 50 KSI. HELIX PITCH SHALL BE 3". LEAD SHALL BE

TWIN HELIX WITH DIAMETERS OF 10" AND 12" WITH A "SEA SHELL" TYPE CUT TO ENABLE DRILLING IN ROCKIER SOIL.

7.4. SUPPORT BRACKET - 3/8 INCH THICK HOT ROLLED STEEL, MIN CAPACITY OF 20,000 LBS. SADDLE DIMENSIONS SHALL MATCH SILL DIMENSIONS

TO THE GREATEST EXTENT POSSIBLE - SIZING SHOWN ON THE DRAWINGS ARE FOR A 4" WIDE SILL.

8. INSTALLATION: CONTRACTOR MAY UTILIZE ANY EQUIPMENT THAT IS APPROVED FOR USE BY THE PILE MANUFACTURER, AND FOLLOW

MANUFACTURER'S INSTRUCTIONS EXACTLY. ONE EXAMPLE OF PORTABLE PILE INSTALLATION EQUIPMENT IS THE CHANCE PORTABLE ANCHOR

INSTALLER FOR REMOTE SITES.

THE LAYOUT AND DESIGN SHOWN HERE ARE CONCEPTUAL. THE CONTRACTOR MUST SUBMIT THE FINAL PILE DESIGN AND LAYOUT, STAMPED BY A

PROFESSIONAL ENGINEER LICENSED IN ALASKA. DEVIATIONS FROM THE REQUIREMENTS OUTLINED HERE MUST BE INCLUDED IN THE STAMPED

DESIGN, AND ARE SUBJECT TO GOVERNMENT APPROVAL.

SPECIFICATIONS: MATERIALS AND CONSTRUCTION OF THIS STRUCTURE IN ACCORDANCE WITH THE STANDARD

SPECIFICATION FOR CONSTRUCTION OF ROADS AND BRIDGES ON FEDERAL HIGHWAY PROJECTS (FP-14) AND

STANDARD SPECIFICATIONS FOR CONSTRUCTION OF TRAILS AND TRAIL BRIDGES ON FEDERAL PROJECTS, CONCRETE: USE STRUCTURAL CONCRETE WITH A 7 SACK MINIMUM MIX, 4 - 6% AIR ENTRAINMENT, SLUMP NOT

EXCEEDING 4 INCHES, AND MAXIMUM AGGREGATE SIZE OF 3/4-INCH. SUBMIT A MIX DESIGN TO BE APPROVED

BY THE C.O., PROVIDE A TROWELED SURFACE FINISH UNLESS OTHERWISE SPECIFIED.

REINFORCING STEEL: FURNISH REINFORCING STEEL CONFORMING TO ASTM A615 (AASHTO M31), GRADE 40 OR

60. PROVIDE 2-INCH CLEAR CONCRETE COVER FOR ALL REBAR, UNLESS NOTED OTHERWISE ON THE PLANS.

HARDWARE AND STRUCTURAL STEEL: SEE SUPERSTRUCTURE DRAWINGS FOR PROJECT DESIGN CRITERIA AND

GENERAL NOTES.

TIMBER & LUMBER: REFER TO THE GENERAL NOTES ON SHEET 34, DRAWING NO 963-10-03, FOR TIMBER &

LUMBER SPECIFICATIONS, ALLOWABLE USE OF TREATMENT, AND FIELD TREATING OF WOOD.

LAG SCREW INSTALLATION: PRE-BORE LAG SCREW HOLES USING TWO DIAMETERS, ONE FOR THE SHANK AND

ONE FOR THE THREADS. THE LEAD HOLE FOR THE SHANK IS TO BE 1/16-INCH LARGER THAN THE SHANK

DIAMETER AND IS TO BE BORED TO THE DEPTH OF PENETRATION OF THE SHANK. THE LEAD HOLE FOR THE

THREADED PORTION IS TO BE 70 PERCENT OF THE BOLT DIAMETER AS SHOWN ON THE PLANS AND IS TO BE

BORED AT LEAST TO THE LENGTH OF THE THREADS. DO NOT DRIVE LAG SCREWS WITH A HAMMER.
