PREPARATION
STRIP AND REMOVE EXISTING VEGETATION, ROOT SYSTEMS, ORGANIC SOILS, DEBRIS, AND
ANY OTHER DELETERIOUS MATERIALS FROM PROPOSED ROADWAY AREAS AND WHERE
MAT OR SHALLOW FOUNDATIONS WILL BE CONSTRUCTED. SUBSEQUENT TO THE SURFACE
CLEARING AND GRUBBING EFFORTS, THE EXPOSED NATURAL SUBGRADE SOILS BENEATH
PROPOSED ROADWAY AREAS AND MAT OR SHALLOW FOUNDATION AREAS SHOULD BE
PROOF-ROLLED TO DETERMINE THE LOCATIONS OF ANY SOFT OR YIELDING SOILS THAT
MAY REQUIRE REMOVAL AND REPLACEMENT. ADDITIONALLY, THE SUBGRADE SOILS
BENEATH ROADWAYS SHOULD BE SCARIFIED, MOISTURE CONDITIONED AND COMPACTED
TO A MINIMUM DEPTH OF TWELVE INCHES. THE MOISTURE CONTENT AND COMPACTION OF
SUBGRADE SOILS SHOULD BE MAINTAINED UNTIL ROADWAY CONSTRUCTION.

1Compaction requirements may be increased by the electrical engineer based on thermal resistivity
analyses. Upper 12 inches should be compacted to 95% within structural areas. Low-volume change
imported soils should be used in structural areas. ASTM D6938 Backscatter Method may be used for
compaction testing in trenches in order to avoid damage to conductors. Frequency of tests may be
increased or decreased at the discretion of the Geotechnical Engineer of Record.

LIFTS FOR FILL SLOPES MUST BE PLACED HORIZONTALLY. BENCHING IS REQUIRED WHEN TYING-IN TO ANY
EXISTING SLOPE OF 5:1 (H:V) OR STEEPER. MINIMUM BENCH HEIGHT SHALL BE 4 FEET, AND A SHEAR KEY IS
REQUIRED AT THE TOE OF THE SLOPE, WITH A MINIMUM SHEAR KEY DEPTH OF 2 FEET AND MINIMUM WIDTH OF
15 FEET, WITH THE BASE OF THE KEY EXCAVATION BEING SLOPED A MINIMUM OF 2% DOWNWARD TOWARD THE
EXISTING SLOPE. THE NEED FOR A BACK DRAIN SHOULD BE EVALUATED BY THE GEOTECHNICAL ENGINEER OF
RECORD WHERE THERE IS POTENTIAL FOR SHALLOW GROUNDWATER, ELEVATED MOISTURE INFILTRATION, OR
PERCHED WATER CONDITIONS.
ROADWAY RECOMMENDATIONS
COMPACTED NATIVE SOILS ACCESS ROAD DESIGN RECOMMENDATIONS:
BASED UPON THE SOILS CONDITIONS ENCOUNTERED IN THE TEST BORINGS, THE USE OF ON-SITE
SOILS FOR CONSTRUCTION OF ON-SITE ROADS IS CONSIDERED ACCEPTABLE.
CONSTRUCTION OF THE UN-SURFACED NATIVE ROADWAYS SHOULD CONSIST OF A MINIMUM OF 12
INCHES OF COMPACTED ON-SITE SOILS.
95 -3%+3%
MATERIALS AND CONSTRUCTION OF ROADWAYS FOR THE PROJECT SHOULD BE IN ACCORDANCE
WITH THE REQUIREMENTS AND SPECIFICATIONS OF THE NORTH CAROLINA DEPARTMENT OF
TRANSPORTATION (NCDOT) OR THE APPLICABLE LOCAL GOVERNING BODY.
WITHOUT THE USE OF ASPHALT CONCRETE OR OTHER HARDENED MATERIAL TO SURFACE THE ROADWAYS,
THERE IS AN INCREASED POTENTIAL FOR EROSION OF THE ROADWAY TO OCCUR. THE UN-SURFACED
ROADS ARE EXPECTED TO FUNCTION WITH PERIODIC MAINTENANCE.
NOTE: THE FILL COMPACTION REQUIREMENTS AND ROADWAY RECOMMENDATION TABLES ARE FOR
REFERENCE ONLY.
CONTRACTOR SHALL REFER TO THE GEOTECHNICAL REPORT PREPARED BY TERRACON CONSULTANTS,
INC. FOR ALL GEOTECHNICAL REQUIREMENTS AND RECOMMENDATIONS.

Drawing Not To Scale
1.Prepare soil before installing rolled
erosion control products (RECPs),
including any necessary application of
lime, fertilizer, and seed.
2.Begin at the top of the channel by
anchoring the RECPs in a 6"(15cm)
deep X 6"(15cm) wide trench with
approximately 12"(30cm) of RECPs
extended beyond the up-slope portion
of the trench. Use ShoreMax mat at the
channel/culvert outlet as supplemental
scour protection as needed. Anchor the
RECPs with a row of staples/stakes
approximately 12"(30cm) apart in the
bottom of the trench. Backfill and
compact the trench after stapling. Apply
seed to the compacted soil and fold the
remaining 12"(30cm) portion of RECPs
back over the seed and compacted soil.
Secure RECPs over compacted soil
with a row of staples/stakes spaced
approximately 12" apart across the
width of the RECPs.
3.Roll center RECPs in direction of water
flow in bottom of channel. RECPs will
unroll with appropriate side against the
soil surface. All RECPs must be
securely fastened to soil surface by
placing staples/stakes in appropriate
locations as shown in the staple pattern
guide.
4.Place consecutive RECPs end-over-end
(Shingle style) with a 4"-6" overlap. Use
a double row of staples staggered 4"
apart and 4" on center to secure
RECPs.
5.Full length edge of RECPs at top of side
slopes must be anchored with a row of
staples/stakes approximately 12"(30cm)
apart in a 6"(15cm) deep X 6"(15cm)
wide trench. Backfill and compact the
trench after stapling.
6.Adjacent RECPs must be overlapped
approximately 2"-5" (5-12.5cm)
(Depending on RECPs type) and
stapled.
7.In high flow channel applications a
staple check slot is recommended at 30
to 40 foot (9 -12m) intervals. Use a
double row of staples staggered
4"(10cm) apart and 4"(10cm) on center
over entire width of the channel.
8.The terminal end of the RECPs must be
anchored with a row of staples/stakes
approximately 12" (30cm) apart in a
6"(15cm) deep X 6"(15cm) wide trench.
Backfill and compact the trench after
stapling.
