SPECIFICATIONS
HAUL ROAD CONSTRUCTION
I. ALL VEGETATION, ORGANIC MATERIAL, MID TOPSOIL SHALL BE
REMOVED PRIOR TO ROAD CONSTRUCTION FROM ALL DISTURBED
AREAS.
2. TOPSOIL IS TO BE STORED FOR FUTURE REPLACEMENT.
3. TEMPORARY EROSION CONTROL MEASURES WILL BE IMPLEMENTED
DURING CONSTRICTION TO MINIMIZE SEDIMENTATION AND
EROSION UNTIL THE DESIGNED DITO-ES MID CULVERTS ARE IN
PLACE,
4. ALL DISTURBED ROADSIDE AREAS ARE TO BE
SEEDED AFTER CONSTRUCTION.
5. CUT SLOPES ARE NOT TO EXCEED 1.5H TO 1V IN UNCONSOLIDATED
MATERIAL OR 0.a TO IV IN ROCK.
6. FILL MATERIAL FOR EMBANKMENT CONSTRUCTION SHALL BE FREE
FROM VEGETATION, TOPSOIL, COAL, FROZEN MATERIAL, AND COAL
PROCESSING WASTES,
7. FILL MATERIAL. SHALL BE PLACED IN UNIFORM HORIZONTAL LIFTS
NOT MORE THAN 12" IN THICKNESS. END DUPING OF FILL
MATERIAL IS PROHIBITED.
H. WERE EMBANKMENTS ARE TO BE PLACED UPON SLOPES EXCEEDING
5H TO 1V 32, THE EXISTING GROUND WILL BE PLOWED, STEPPED
OR IF IN BED ROCK( KEYED IN A MANNER WHICH INCREASES STA-
BILITY OF THE FILL, THE KEYWAY WILL BE A MINI" OF 1D
FEET WIDE AM MUST D(TEW A MINIMUM OF 2 FEET BELOW THE
TOE OF THE FILL,
9. WHEN FILL MATERIAL CONSISTS OF LARGE -SIZE ROCK THAT MAKES
PLACING IT IN 12" LAYERS IMPOSSIBLE, THE LAYERS SHALL NOT
EXCEED THE THICKNESS OF THE AVERAGE SIZE OF ROCK USED.
IN NO CASE WILL A LAYER EXCEED 36" IN THICKNESS, THE FINAL
LAYER MUST NOT EXCEED 32" IN THICKNESS.
)fl. EACH LAYER OF THE EMBANKMENT SHALL BE COMPLETED, LEVELED,
AND COMPACTED BEFORE THE SUCCEEDING LAYER IS PLACED,
LAYERS SHALL BE COMPACTED EVENLY BY ROUTING, HAULING AMID
LEVELING EQUIPMENT OVER THE ENTIRE WIDTH OF THE EMBANK-
MENT UNTIL NO VISIBLE HORIZONTAL MOVEMENT OF THE FILL IS
APPARENT.
11. MATERIAL WILL BE PLACED IN AN EMBANKMENT ONLY WHEN ITS
MOISTURE CONTENT IS WITHIN 54" OF OPTIMUM AS DETERMINED BY
AASHTo T-% OR T -18) COMPACTION TESTS. IN ALL CASES THE
LIFTS WILL BE COMPACTED TO NOT LESS THAN 0 OF THE
MAXIMUM DENSITY (STAINED IN LABORATORY COMPACTION TESTS,
AT LEAST ONE LABORATORY TEST WILL BE PERFORMED FOR EACH
DISTINCTIVE MATERIAL TO BE USED IN EMBANKMENT CONSTRUCTION.
12. EMBANKMENT SLOPES SHALL NOT EXCEED 2H TO D UNLESS EM-
BANKMENT MATERIAL IS A MINIMUM OF 0 ROCK THEN SLOPES
SHALL NOT EXCEED 1.35H TO 1V.
13. ROADSIDE DRAINAGE DITCHES ARE TO BE "V" sHAPED WITH 2H TD
1V SIDE SLOPES.
14. ALL CULVERTS SHALL BE COVERED BY COMPACTED FILL TO A MINI-
MUM DEPTH OF 1 FOOT,
16. DITCHES AMID CULVERTS SHALL BE KEPT FREE OF DEBRIS; DAMAGED
OR CRUSHED CULVERTS MST BE REPLACED.
17. HAUL ROADS SHALL BE SURFACED WITH GRAVEL, SCORIA, CRUSHED
ROCK OR ASPHALT.
18. ALL ROADS TO BE sLPERELEVATED AT CURVES WITH 0.04 FT,/FT.
RECOMMENDED. SUPERELEVAT1oN SHALL NOT EXCEED 0.06 F UFT.
19, HAIL ROADS SHALL BE MAINTAINED BY BLARING, FILLING OF POT -
HDLES, REPLACEMENT OF THE ROAD SURFACE, REVEIETATION, BRUSH
REMOVAL, WATERING FOR DUST CONTROL, AND MINOR RECONSTRUC-
TION AS NECESSARY SO THAT THE DESIGN STANDARDS ARE MET
THROUGHOUT THE LIFE OF THE FACILITY.
20. THE DESIGN AND CONSTRUCTION OR RECONSTRUCTION OF HAIL. FCADS
SHALL BE CERTIFIED BY A QUALIFIED REGISTERED PROFESSIONAL
ENGINEER.
