1. Blue tags, or copies of blue tags from each seed lot. Only certified, blue-tagged seed shall be used.

The blue tag represents a field certification and serves as evidence of the genetic purity and varietal identity of the seed contained in the seed lot.

2. Labels which indicate the percentage composition of various species in the seed mix.

3. Copies of Seed Analysis Reports from a certified seed analyst for each seed lot used in the specified mix. Purchaser will obtain this report from the seed provider. Analysis report must include at a minimum, content of any noxious weed seeds listed on the current “Montana Noxious weeds list”.

Only after the Forest Service has reviewed documentation to verify that the seed does not contain any weeds on the current “Montana Noxious Weeds List”, will the seed be accepted and used.

Fertilizer shall be applied at a rate of 100 pounds per acre in one application by the Dry Method and have a chemical analysis as listed below:

Nutrient Percent

Nitrogen (N) 16

Phosphorus (P2O5) 16

Potassium (K) 16

625.08 Mulching

Delete the entire subsection and replace with the following:

Apply straw or hay mulch that is Montana certified weed free within 48 hours after seeding by the following methods.

(a) Dry Method. Apply mulch by hand or with a mechanical spreader at a uniform rate of

2000 pounds per acre. Apply mulch by hand in areas inaccessible to mulching equipment.

Apply mulch uniformly over the entire disturbed area.

Add the following section:

725.40 High-Strength Nonshrink Grout

Furnish grout that is packaged and ready for use with the addition of water at the construction site. Ensure that each bag is stamped to show the last date on which it may be used. Use grout that consists of a hydraulic cementitious system, graded and processed natural fine aggregate, and additional technical components such that the product meets the following conditions:

(a) Free of inorganic accelerators, including chlorides.

(b) Free of oxidizing catalysts.

(c) Free of gas-producing agents.

(d) When mixed to 130 percent flow on flow table (ASTM C 230 at 10 drops), it does not reduce in linear dimension when tested in accordance with ASTM C157.

Take measurements at 72 hours and 7 days.

(e) Produces no bleeding for the first 2 hours after mixing when mixed to 130 percent flow on flow table (ASTM C 230 at 10 drops), as tested in accordance with

ASTM C232.

(f) Has a minimum strength as follows when tested in accordance with ASTM C 109:

(1) After 72 hours, 25 MPa (3500 psi).

(2) At 7 days, 40 MPa (6000 psi).

(3) After 28 days, 50 MPa (7200 psi).

Provide performance characteristics at 115 to 120 percent flow on flow table

(ASTM C 230 at 10 drops).

(g) It must be designed, as stated by the manufacturer, to be mixed, placed, and cured at atmospheric temperatures of 5 O C to 30

O C (40

O F to 85

O F). Submit products proposed for use for approval by the CO and accompany them with manufacturer’s submittals substantiating all requirements in this subsection, including graphs or charts showing the time, temperature, and humidity requirements for curing to achieve the specified grout strengths; and recommendations for storage, mixing, application, and curing procedures.

As specified as grout on the contract plans, the following products meet the above requirements.

1. MASTERFLOW 928 GROUT, manufactured by Chemrex.

2. CRYSTEX GROUT, manufactured by L&M Construction Chemicals, Inc.

3. CEMENT ALL, manufactured by CTS Cement Manufacturing Co.

4. SURE-GRIP HIGH PERFORMANCE GROUT manufactured by Dayton Superior.

725.41 Mortar

Furnish mortar that is packaged and ready for use with the addition of water at the construction site. Ensure that each bag is stamped to show the latest date on which it may be used. Use mortar that consists of a cementitious system made up of:

(a) Natural aggregate, 3/8” maximum size, that meets the requirements specified in

ASTM C 33 except for grading. Accomplish grading by blending sieve sizes to obtain the optimum density.

(b) Metallic aggregate free from nonferrous material, soluble alkaline compounds, and visible rust.

(c) Water reducers, workability agents, air-entraining agents, and catalysts.

Blend the materials to minimize bleeding, increase workability, resist exposure to freeze-thaw cycles and deicing salts, and prevent shrinkage within and at the perimeter of the patch, keyway, or other area to be filled.

Ensure that the minimum compressive strength of the mortar, as tested by ASTM C 109 for a 3” slump, is:

24-hour...........................................................................................35MPa (5000 psi)

7-day...............................................................................................60 MPa (8500 psi)

28-day.............................................................................................70 MPa (10,000 psi)

Ensure that the durability of the products when tested at 300 cycles, ASTM C 666, procedure A is:

Submerged in: DF (%)

Water 98

5% CaCl2 solution 95

5% NaCL solution 85

Ensure that the scaling resistance has a rating of 3, Moderate Scaling, after 50 cycles when tested in accordance with ASTM C 672.

Provide certification from the manufacturer that the product is compatible for work that is 1” or more in depth and more than 1” in width; and where the mixing, placing, and curing temperatures may range from 5 O C to 30

O C (40

O F to 85

O F).

Submit products proposed for use to the CO for approval, and accompany them with the manufacturer’s submittals substantiating all requirements in this section, including (1) graphs or charts showing the time, temperature, humidity, and curing requirements to achieve mortar strengths equal to the adjacent concrete; and (2) complete recommendations for storage, mixing, application, and curing procedures.
