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 TRENCH WIDTH MUST ALLOW ROOM FOR PROPER COMPACTION OF HAUNCH MATERIALS UNDER THE PIPE ARCH.
THE TRENCH WIDTH IS THE MINIMUM AMOUNT REQUIRED FOR PROPER INSTALLATION AND TO SUPPORT HORIZONTAL PRESSURE FROM THE
PIPE. THE MANUFACTURER'S SUGGESTED MINIMUM VALUE IS: 1.5S + 12".
1a MINIMUM EMBANKMENT WIDTH (IN FEET) FOR INITIAL FILL ENVELOPE:
3.OS BUT NO LESS THAN S + 4'-0".
82"-112"

3" x 1"
2 FOUNDATION SHALL BE WELL CONSOLIDATED. STABLE & CAPABLE OF SUPPORTING FILL MATERIAL LOAD.
3 OPEN -GRADED GRANULAR BEDDING MATERIAL SHALL BE A RELATIVELY LOOSE MATERIAL THAT IS ROUGHLY SHAPED TO FIT THE BOTTOM OF
THE PIPE ARCH, 4" TO 6" IN DEPTH. SUGGESTED PARTICLE SIZE IS 1/2 CORRUGATION DEPTH. THE WIDTH OF BEDDING SHOULD BE THE EXTENTS
OF THE INVERT OF THE PIPE ARCH.
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. REFER TO AASHTO
26.5.2, 26.5.4 OR ASTM B788 10.3 TO PROPERLY ADDRESS CORNER BEARING PRESSURE.
5a THE BACKFILL MATERIAL SHALL BE A FREE -DRAINING, ANGULAR, WASHED -STONE PER AASHTO M 43 SIZE #3 WITH A'/z" - 2" PARTICLE SIZE OR
APPROVED EQUAL. MATERIAL SHALL BE PLACED IN 12" MAXIMUM LIFTS AND SHALL BE WORKED INTO THE PIPE HAUNCHES BY MEANS OF
SHOVEL -SLICING, RODDING, AIR -TAMPER, VIBRATORY PLATE OR OTHER EFFECTIVE METHODS. COMPACTION IS CONSIDERED ADEQUATE WHEN
A DENSITY EQUIVALENT TO 90% STANDARD PROCTOR IS ACHIEVED OR WHEN NO FURTHER YIELDING OF THE MATERIAL IS OBSERVED UNDER
THE COMPACTOR OR UNDER FOOT. THE PROJECT ENGINEER OR HIS REPRESENTATIVE MUST BE SATISFIED WITH THE LEVEL OF COMPACTION.
INADEQUATE COMPACTION CAN LEAD TO EXCESSIVE PIPE DEFLECTIONS AND SETTLEMENT OF THE SOILS OVER THE SYSTEM. BACKFILL SHALL
BE PLACED SUCH THAT THERE IS NO MORE THAN A TWO -LIFT DIFFERENTIAL BETWEEN THE SIDES OF ANY PIPE IN THE SYSTEM AT ALL TIMES
DURING THE BACKFILL PROCESS. BACKFILL SHALL BE ADVANCED ALONG THE LENGTH OF THE SYSTEM AT THE SAME RATE TO AVOID
DIFFERENTIAL LOADING ON ANY PIPES IN THE SYSTEM.
6 INITIAL OPEN GRADED GRANULAR BACKFILL ABOVE PIPE ARCH MAY INCLUDE ROAD BASE MATERIAL (AND RIGID PAVEMENT IF APPLICABLE).
SEE TABLE ABOVE. INITIAL BACKFILL OF 6" PER ENGINEER OF RECORD.
6a TOTAL HEIGHT OF COMPACTED COVER IS MEASURED FROM TOP OF PIPE ARCH TO BOTTOM OF FLEXIBLE PAVEMENT OR TOP OF RIGID
PAVEMENT.
7 FINAL BACKFILL MATERIAL SELECTION AND COMPACTION REQUIREMENTS SHALL FOLLOW THE PROJECT PLANS AND SPECIFICATIONS PER THE
ENGINEER OF RECORD. PER ENGINEER OF RECORD. 2" CLEAN ROCK WITH 40% POROSITY.
NOTES:
• GEOTEXTILE SHALL BE USED AS REQUIRED TO PREVENT SOIL MIGRATION.
• FOR MULTIPLE BARREL INSTALLATIONS THE RECOMMENDED STANDARD SPACING BETWEEN
PARALLEL PIPE ARCH RUNS SHALL BE SPAN/2 BUT NO LESS THAN 12", OR 36" FOR PIPE SPANS
108" AND LARGER. CONTACT YOUR CONTECH REPRESENTATIVE FOR NONSTANDARD SPACING.
