\(1\) Furnish spalls and rock fragments graded to provide a stable dense
mass.

\(2\) The volume of a rock with these cubic dimensions has a mass
approximately equal to the specified rock mass.

\(3\) Furnish rock with breadth and thickness at least one-third its
length.

**705.03 Rock for Masonry Structures.** Furnish sound, durable rock that
is native to the vicinity of the work or is similar in texture and color
to the native rock and has been proven satisfactory for the intended
use.

Furnish dimensioned masonry rock free of reeds, rifts, seams,
laminations, and minerals that may cause discoloration or deterioration
from weathering.

**(a) Sizes and shapes.** Do not use rock with depressions or
projections that might weaken it or prevent it from being properly
bedded.

When no dimensions are shown on the plans, furnish the rocks in the
sizes and face areas necessary to produce the general characteristics
and appearance indicated on the plans.

Unless otherwise specified, furnish rock fragments with the following
dimensions:

**(1)** Minimum thickness 5 inches

**(2)** Minimum width 12 inches or 1½ times the thickness, whichever is
greater

**(3)** Minimum length 1½ times the width

**(4)** Rocks with volume ≥ 1 cubic foot 50% min.

When headers are required, furnish headers with lengths no less than the
width of bed of the widest adjacent stretcher plus 12 inches.

**(b) Dressing.** Remove all thin or weak portions. Dress face rock bed
and joint lines to a maximum variation from true line as follows:

**(1)** Rubble masonry 1½ inches

**(2)** Class B masonry 3/4 inch

**(3)** Class A masonry 1/4 inch

**(4)** Dimensioned masonry Reasonably true

**(c) Bed surfaces.** Dress face rock bed surfaces normal to the face to
a depth of 3 inches. Beyond that point, the departure from normal may
not exceed 1 inch in 12 inches for dimensioned masonry or 2 inches in 12
inches for all other classes.

**(d) Joint surfaces.** For dimensioned masonry, dress face rock joint
surfaces normal to the bed surface. For all other classes of masonry,
dress face rock joint surfaces to form an angle with the bed surface of
not less than 45 degrees.

Dress face rock joint surfaces normal to the face to a depth of 2
inches. Beyond that point, the departure from normal may not exceed 1
inch in 12 inches.

Do not round corners at the meeting of the bed and joint lines in excess
of the following radii:

**(1)** Rubble masonry 1½ inches

**(2)** Class B masonry 1 inch

**(3)** Class A masonry No rounding

**(4)** Dimensioned masonry No rounding

**(e) Arch ring rock joint surfaces.** Dress ring rock joint surfaces
radial to the arch or normal to the front face to a depth of 3 inches.
Beyond that point, the departure from the radial or normal may not
exceed 3/4 inch in 12 inches.

Dress the back surface adjacent to the arch barrel concrete parallel to
the front face and normal to the intrados to a depth of 6 inches. When
concrete is placed after the masonry is constructed, vary adjacent ring
stones at least 6 inches in depth.

**(f) Finish for exposed faces.** Remove all drill or quarry marks from
exposed faces. Pitch face stones to the line along all beds and joints.
Finish the exposed faces as specified in the contract. The following
symbols are used to represent the type of surface or dressing specified:

**(1) Fine pointed (F.P.).** Make point depressions approximately 3/8
inch apart. Limit surface variations to 1/8 inch or less from the pitch
line.

**(2) Medium pointed (M.P.).** Make point depressions approximately
5/8 inch apart. Limit surface variations to 1/4 inch or less from the
pitch line.

**(3) Coarse pointed (C.P.).** Make point depressions approximately 1⅛
inches apart. Limit surface variations to 3/8 inch or less from the
pitch line.

**(4) Split or seam face (S.).** Provide a smooth appearance, free from
tool marks, with no depressions below the pitch line, and no projection

\(1\) For turf reinforcement mats containing degradable components,
obtain all property values on the non-degradable portion of the matting
alone.

\(2\) Minimum average roll values, machine direction only.

\(3\) Field conditions with high loading and high survivability
requirements may warrant the use of turf reinforcement mats with tensile
strengths of 3,000 pounds per foot or greater.

\(4\) Minimum shear stress the turf reinforcement mat (fully vegetated)
can sustain without physical damage or excess erosion (\>1/2-inch soil
loss) during a 30‑minute flow event in large-scale testing. These
performance test values should be supported by periodic bench scale
testing under similar test conditions and failure criteria using Erosion
Control Technology Council Test Method #3.

\(5\) Other large-scale test methods determined acceptable by the CO.

## Section 714. --- GEOTEXTILE AND GEOCOMPOSITE DRAIN MATERIAL

**714.01 Geotextile.** Use long-chain, synthetic polymers, composed at
least 95 percent by mass of polyolefins or polyesters, to manufacture
geotextile or the threads used to sew geotextile. Form the geotextile,
including selvedges, into a stable network such that the filaments or
yarns retain their dimensional stability relative to each other.

**(a) Physical requirements.** Conform to the following tables for the
type of geotextile specified:

**(1) Type I (A - F)** Subsurface drainage Table 714-1

**(2) Type II (A - C)** Separation Table 714-2

**(3) Type III (A - B)** Stabilization geotextile Table 714-3

**(4) Type IV (A - F)** Permanent erosion control Table 714-4

**(5) Type V (A - C)** Temporary silt fence Table 714-5

**(6) Type VI** Paving fabric Table 714-6

All property values, with the exception of apparent opening size (AOS),
in these specifications represent minimum average roll values in the
weakest principal direction (i.e., average test results of any roll in a
lot sampled for conformance or quality assurance testing shall meet or
exceed the specified values). Values for AOS represent maximum average
roll values.

Elevate and protect rolls with a waterproof cover if stored outdoors.
When using a geotextile for a permanent installation, limit the
geotextile exposure to ultraviolet radiation to less than 10 days.

**(b) Evaluation procedures.** Geotextile will be evaluated under
Subsection 106.03. Furnish a commercial certification including the name
of the manufacturer, product name, style number, chemical composition of
the filaments or yarns, and other pertinent information to fully
describe the geotextile.

When samples are required, remove a 3-foot long, full-width sample from
beyond the first outer wrap of the roll. Label the sample with the lot
and batch number, date of sampling, project number, item number,
manufacturer, and product name.

subsurface drainage geotextile attached to or encapsulating the core.
Include all necessary fittings and material to splice one sheet, panel,
or roll to the next and to connect the geocomposite drain to the
collector and outlet piping.

For the drainage core, use long chain synthetic polymers composed at
least 85 percent by mass of polypropylene, polyester, polyamide,
polyvinyl chloride, polyolefin, or polystyrene. Fabricate the core in
sheets, panels, or rolls of adequate strength to resist installation
stresses and long-term loading conditions. Build the core up in
thickness by means of columns, cones, nubs, cusps, meshes, stiff
filaments, or other configurations.

Furnish geocomposite drains with a minimum compressive strength of 40
pounds per square inch when tested according to ASTM D 1621, procedure
A. Furnish splices, fittings, and connections with sufficient strength
to maintain the integrity of the system during construction handling and
permanent loading without impeding flow or damaging the core.

Elevate and protect sheets, panels, or rolls with a waterproof and
ultraviolet resistant cover if stored outdoors.

When using a geocomposite drain for a permanent installation, limit the
geocomposite exposure to ultraviolet radiation to less than 10 days.

Geocomposites will be evaluated under Subsection 106.03. When samples
are required, provide a 3-foot square sample from products supplied as
sheets or panels or a 3-foot length full-roll width sample from products
supplied in rolls. Label the sample with the lot and batch number, date
of sampling, project number, item number, manufacturer, and product
name.

**(a) Geocomposite underdrains.** The horizontal and vertical flow of
water within the core shall interconnect at all times for the full
height of the core. The drainage core with the geotextile fully
encapsulating the core shall provide a minimum flow rate of 5 gallons
per minute per foot of width when tested according to ASTM D 4716 under

movement cannot occur either during handling or after placement. Achieve
bonding using nonwater-soluble adhesive, heat sealing, or other methods
recommended by the manufacturer. Do not use adhesive on areas of the
geotextile fabric where flow is intended to occur.

If heat sealing is used, do not weaken the geotextile below the required
strength values. Extend the geotextile below the bottom of the core a
length sufficient to completely encapsulate the collector pipe.

**(b) Geocomposite sheet drains.** The horizontal and vertical flow of
water within the sheet drain shall interconnect at all times for the
full height of the core. The drainage core with the geotextile laminated
to one side of the core shall provide a minimum flow rate of 5 gallons
per minute per foot of width when tested according to ASTM D 4716 under
test conditions (1) through (5) in (a) above.

If core construction separates the flow channel into two or more
sections, only the flow rate on the in-flow face is considered in
determining the core\'s acceptability.

Firmly attach the geotextile to the core so folding, wrinkling, or other
movement cannot occur either during handling or after placement. Achieve
bonding using nonwater-soluble adhesive, heat sealing, or other method
recommended by the manufacturer. Do not use adhesive on areas of the
geotextile fabric where flow is intended to occur.

If heat sealing is used, do not weaken the geotextile below the required
strength values. Extend the geotextile below the bottom of the core
length sufficient to completely encapsulate the collector pipe.

**(c) Geocomposite pavement edge drains.** The geotextile shall tightly
encapsulate the geocomposite edge drain. The edge drains shall permit
in-flow from both sides. The drain core with the geotextile in place
shall provide a minimum flow rate of 15 gallons per minute per foot of
width when tested according to ASTM D 4716 under test conditions (1)
through (5) in (a) above, except the gradient shall be 0.1.

If the geocomposite polymer core separates the flow channel into two or
more parts, consider only the tested flow rate of the channel facing the
pavement.

All pipe and pipe fittings used for an outlet to the edge drain shall be
non-perforated plastic pipe conforming to Subsection 706.08.

The solvent cement for the outlet pipe and fittings shall be according
to ASTM D 2564. The material composition of the outlet fittings shall be
compatible for direct solvent welding to PVC.
