NOTE: IF SALTING AGENTS FOR SNOW AND ICE REMOVAL ARE USED ON OR NEAR THE
PROJECT, A GEOMEMBRANE BARRIER IS RECOMMENDED WITH THE SYSTEM. THE
GEOMEMBRANE LINER IS INTENDED TO HELP PROTECT THE SYSTEM FROM THE
POTENTIAL ADVERSE EFFECTS THAT MAY RESULT FROM A CHANGE IN THE
SURROUNDING ENVIRONMENT OVER A PERIOD OF TIME. PLEASE REFER TO THE
CORRUGATED METAL PIPE DETENTION DESIGN GUIDE FOR ADDITIONAL INFORMATION.

MINIMUM HEIGHT OF
COVER FOR PIPE
ARCHES IS SPAN/8 BUT
NOT LESS THAN 12" FOR
CORRUGATIONS:
• 2 2/3" x 1/2"
• 3"x1"
(SEE NOTE 6)
BACKFILL REQUIREMENTS FOLLOW THE GUIDELINES OF AASHTO LRFD BRIDGE DESIGN (SEC 12) AND CONSTRUCTION (SEC 26)
1 MINIMUM TRENCH WIDTH MUST ALLOW ROOM FOR PROPER COMPACTION OF HAUNCH MATERIALS UNDER THE PIPE ARCH.
THE MINIMUM TRENCH WIDTH (12.6.6.1):
SPAN > 12": 1.5S + 12"
1a MINIMUM EMBANKMENT WIDTH (IN FEET) FOR INITIAL FILL ENVELOPE (12.6.6.2):
• SPAN < 24": 3.OS
• SPAN 24" - 112": S + 4'-0"
2 THE FOUNDATION UNDER THE PIPE ARCH AND SIDE BACKFILL SHALL BE ADEQUATE TO SUPPORT THE LOADS ACTING UPON IT (26.5.2).
3 ENGINEER TO DETERMINE IF BEDDING IS REQUIRED. BEDDING MATERIAL SHALL BE A RELATIVELY LOOSE MATERIAL THAT IS ROUGHLY
SHAPED TO FIT THE BOTTOM OF THE PIPE ARCH, AND A MINIMUM OF TWICE THE CORRUGATION DEPTH IN THICKNESS, WITH THE
MAXIMUM PARTICLE SIZE OF ONE-HALF OF THE CORRUGATION DEPTH (26.3.8.1). WIDTH OF BEDDING TO BE EXTENTS OF THE INVERT OF
THE PIPE ARCH (26.5.3, FIG. 26.5.3-1).
4 CORRUGATED ALUMINUM PIPE ARCH (CAPA) [CORLIX PIPE ARCH].
5 HAUNCH ZONE MATERIAL SHALL BE HAND SHOVELED OR SHOVEL SLICED INTO PLACE TO ALLOW FOR PROPER COMPACTION
(26.5.2 & 26.5.4).
5a INITIAL BACKFILL FOR PIPE EMBEDMENT TO MEET AASHTO A-1, A-2 OR A-3 CLASSIFICATION, OR APPROVED EQUAL, COMPACTED TO 90%
STANDARD PROCTOR (T 99). MAXIMUM PARTICLE SIZE NOT TO EXCEED 3" (12.4.1.2). ALL LIFTS SHALL BE PLACED IN A CONTROLLED
MANNER. IT IS RECOMMENDED THAT LIFTS NOT EXCEED AN 8" UNCOMPACTED LIFT HEIGHT TO PREVENT UNEVEN LOADING, AND THE
LESSER OF 1/3 THE SPAN OR 24" AS THE MAXIMUM DIFFERENTIAL SIDE -TO -SIDE (26.5.4).
6 INITIAL BACKFILL ABOVE PIPE ARCH MAY INCLUDE ROAD BASE MATERIAL (AND RIGID PAVEMENT IF APPLICABLE).SEE TABLE ABOVE.
INITIAL BACKFILL OF 7.50" PER ENGINEER OF RECORD
6a TOTAL HEIGHT OF COMPACTED COVER FOR CONVENTIONAL HIGHWAY LOADS IS MEASURED FROM TOP OF PIPE ARCH TO BOTTOM OF
FLEXIBLE PAVEMENT OR TOP OF RIGID PAVEMENT (12.6.6.3).
7 FINAL BACKFILL MATERIAL SELECTION AND COMPACTION REQUIREMENTS SHALL FOLLOW THE PROJECT PLANS AND SPECIFICATIONS
PER THE ENGINEER OF RECORD (26.5.4.1). PER ENGINEER OF RECORD, 10.5" CLEAN ROCK WITH 40% POROSITY.
NOT TO SCALE NOTES:
•
ENGINEER TO DETERMINE IF GEOTEXTILE SHOULD BE CONSIDERED FOR USE TO PREVENT SOIL MIGRATION INTO VARYING SOIL TYPES (PROJECT ENGINEER).
•
FOR MULTIPLE BARREL INSTALLATIONS THE RECOMMENDED STANDARD SPACING BETWEEN PARALLEL PIPE ARCH RUNS SHALL BE SPAN/3 BUT NO LESS THAN
12", OR 36" FOR PIPE ARCH SPANS 108" AND LARGER. CONTACT YOUR CONTECH REPRESENTATIVE FOR NONSTANDARD SPACING (SEE TABLE C12.6.7-1).
