AEC Premier Straw Double Net FibreNet, Erosion Control Blanket (ECB)

Dear Ms. Malusky:

This letter report presents the results for large-scale slope erosion tests performed on AEC Premier

Straw Double Net FibreNet ECB, rolled erosion control product (RECP), over loam. Included are

data developed for target rainfall intensities from 2 to 6 in/hr (5 to 15 cm/hr). All testing work was

performed in general accordance with the ASTM D 6459, Standard Test Method for Determination

of Rolled Erosion Control Product (RECP) Performance in Protecting Hillslopes from Rainfall-

Induced Erosion. Generated results were used to develop the following general cover factor (C-

Factor) for the tested material:

C-Factor AEC Premier Straw Double Net FibreNet ECB & 1.7 staples/sy = 0.038 for cumulative R-Factor ≤ 162;

Eqn: C = 0.00000172R1.96308492

TRI is pleased to present this final report. Please feel free to call if we can answer any questions or

provide any additional information.

Sincerely,

SLOPE TESTING REPORT


TESTING EQUIPMENT AND PROCEDURES

Overview of Test and Apparatus

TRI/Environmental, Inc.'s (TRI's) large-scale slope erosion testing facility is located at the Denver

Downs Research Farm in Anderson, SC. Testing oversight is provided by C. Joel Sprague, P.E. The

large-scale testing reported herein was performed in accordance with ASTM D 6459, on 3:1 slopes

using loamy soil test plots measuring 40 ft long x 8 ft wide. The simulated rainfall was produced by

ten “rain trees” arranged around the perimeter of each test slope. Each rain tree has four sprinkler

heads atop a 15 ft riser pipe. The rainfall system has been calibrated prior to testing to determine the

number of sprinkler heads and associated pressure settings necessary to achieve target rainfall

intensities and drop sizes. The target rainfall intensities are 2, 4, and 6 in/hr and are applied in

sequence for 20 minutes each. Three replicate test slopes covered by the same rolled erosion control

product (RECP) submitted were tested. The erosion resistance provided by the product tested is

obtained by comparing the protected slope results to control (bare soil) results. Tables and graphs of

rainfall versus soil loss are generated from the accumulated data.

Preparation of the Test Slopes

The initial slope soil veneer (12-inch thick minimum) is placed and compacted. Compaction is

verified to be 90% (± 3%) of Proctor Standard density using ASTM D 2937 (drive-cylinder method).

Subsequently, the test slopes undergo a “standard” preparation procedure prior to each slope test.

First, any rills or depressions resulting from previous testing are filled in with test soil and subject to

heavy compaction. The entire test plot is then tilled to a depth not less than four inches. The test

slope is then raked to create a slope that is smooth both side-to-side and top-to-bottom. Finally, a

steel drum roller is rolled down-and-up the slope 3 times proceeding from one side of the plot to the

other. The submitted erosion control product is then installed as directed by the client.

Installation of Erosion Control Product on Test Slopes

As noted, the submitted erosion control product was installed as directed by the client. For the tests

reported herein, the RECP was anchored with 6-inch staples at 1.7 staples per square yard.

Specific Test Procedure

Immediately prior to testing, rain gauges are placed at the quarter points (i.e. 10, 20, 30 ft) on the

slope. The slope is then exposed to sequential 20-minute rainfalls having target intensities of 2, 4,

and 6 inches per hour. All runoff is collected during the testing. Additionally, periodic sediment

concentration grab samples are taken and runoff rate measurements are made. Between rainfall

intensities, the rainfall is stopped and rainfall depth is read in the three rain gauges, valves are

adjusted to facilitate the subsequent rainfall intensity, and empty collection vessels are positioned to

collect subsequent runoff.

After allowing for sediments to settle, water is decanted from the collected runoff. The remaining

solids are used to determine “bulk” soil loss. Bulk soil loss is measured by drying all collected

sediments.

TEST RESULTS

The Cover Management (C) Factor from the Revised Universal Soil Loss Equation (RUSLE) of the

USDA-ARS Agricultural handbook 703 is the reported performance measure for slopes determined

from this testing. The C-Factor and R-Factor reported herein are related through RUSLE by the

following relationship:

A = R x K x LS x C x P

where: A = the computed soil loss in tons per acre (measured/calculated from test);

R = the rainfall erosion index (measured/calculated from test);

K = the erodibility of the soil (calculated from test – see Figure 9);

LS = the topographic factor (2.78 for 8 x 40 ft slope);

C = the cover factor = ratio of protect soil loss to control soil loss (1.0 for control); and

P = the practice factor (1.0 for all test slopes).

Total soil loss and the associated rainfall depth measured during the testing are the principle data

used to determine the C Factor. The cumulative C-Factors shown in Table 3 are the ratio of the soil

loss from the protected condition at a calculated cumulative R-Factor divided by the cumulative soil

loss from the control plot (Figure 9) at that same R-Factor.

In all cases, the soil loss and associated rainfall data for both protected and control conditions are

used to develop a normalized cumulative graph of R-Factor versus C-Factor (R factor = total kinetic

energy of the storm (E) times its maximum 30-minute Intensity (I)). The maximum average

normalized cumulative R-Factor calculated for the target test events: 2 in/hr for 20 minutes + 4 in/hr

for 20 minutes + 6 in/hr for 20 minutes, is R = 231 assuming all raindrops achieve terminal velocity.

Since this is not the case, the R-Factor must be “scaled” to reflect the kinetic energy associated with

the actual velocity achieved by each size of raindrop. For the tests reported herein, the C-Factor

associated with this scaled R-Factor of 162 is the reported performance value. This facilitates

product-to-product comparison of test results at a common point of the storm event.

Graphs of R-Factor versus C-Factor for the protected condition and Soil Loss versus R-Factor for the

control condition are shown in Figures 8 and 9, respectively. Figure 8 includes the best regression

line fit to the test data to facilitate the determination of the C-factor. Figure 8 additionally allows

users of this report to evaluate performance at other points in the model storm by selecting the R

factor (and the corresponding C Factor) that may fit local conditions.

According to the test procedure ASTM D6459, a test may be stopped in the event of catastrophic soil

loss, as determined by the lab. AASHTO NTPEP ECP Panel has determined this practice places an

undue amount of subjectivity into the test. In lieu of stopping the test, the test is run to completion.

The runoff and sediment loss just prior to catastrophic failure is separated from that occurring after.

This additional point is used in the creating of the Soil Loss verses R Factor Graph.

The tests reported herein did not experience catastrophic slope failure. Linear (R2=0.64), power

(R2= 0.92), and polynomial (R

2 = 0.64) fits were the best fits evaluated.

The overall C-Factor information shown in Table 4 is derived from Figure 8 which relates the C-

Factors and associated R-Factors given in Table 3.
