5. Testing Bituminous Paving:

a. Prior to producing the bituminous mixtures, the Contractor shall submit a Job Mix Formula in writing as specified in ODOT Section 448 for each of the various asphalt concrete mixes proposed for the site.

b. The Contractor will sample materials at the plant to be delivered to the site and test for conformance with the specifications and the approved job mix formula, according to ODOT Section 448. The Contractor shall supply to the Contracting Officer results of these tests on a regular basis at no cost to the Government.

c. The Contractor's independent laboratory shall provide a 3 ½ inch minimum diameter core for each 300 square yards of paving as depth verification at no cost to the Government. In place compacted thickness shall not vary more than ½" from that required. Repair or remove and replace deficiencies as directed.

6. Rolling: Leveling course shall be thoroughly compacted by rolling with a 2- or 3- wheeled power driven roller. Rolling shall begin at sides and progress to center. Rolling shall continue until material does not creep or wave ahead of roller wheels. Areas of pavement inaccessible to roller shall be satisfactorily compacted by means of approved tampers.

7. After the last course has received the final rolling, no vehicular traffic shall be permitted on the pavement until it has hardened sufficiently that such traffic will not damage finished surface, but in no case less than 12 hours after surface is finally rolled.

8. The variation between any two contacts with the surface shall not exceed ¼" from a 10' straightedge. Any deviations from planarity required must be corrected during the initial application of material.

I. Jointing Asphalt Concrete Paving With Other Surfaces:

1. Thoroughly clean interface of other surface. Saw cut edges of existing pavement to ensure neat and uniform bonding surface.

2. Prior to applying bituminous leveling course, uniformly apply at the interface of other surfaces asphalt concrete pavement with specified tack coat.

3. Match adjacent grade of existing pavement with finished surface of asphalt. Special care should be taken in walk areas to ensure transition meets ADA requirements.

4. Apply the specified sealant at the joint of adjacent horizontal and vertical surfaces.

J. Pavement Clean-Up: Remove all excess material and debris of any kind and place in first-class condition upon completion of paving to be ready for backfilling of edging material against paving edges.

K. Pavement Marking: Install pavement marking as specified in ODOT 640. Clean area by brooming, air blasting or other acceptable method. Parking space lines shall be 4-inches wide solid yellow line. Directional arrows shall be solid yellow. Stop Bar shall be 12-inches wide solid white line. Two (2) coats are required. Contractor shall take necessary precautions to keep vehicular and pedestrian traffic off freshly painted areas.

02931 EDGING, SEEDING & MULCH

A. Work in this section consists of installing edging material, seeding, fertilizing and mulching area.

B.

Edging Material:

1.

Where the soil is bare topsoil shall be replaced. It is preferred that the original topsoil be stockpiled during construction and put back in place once grading and paving is complete. Where original topsoil is not available, and the Contracting Officer has determined the remaining soil material is not suitable, the contractor will provide topsoil that is approved by the Contracting Officer.

2.

After areas that are to be seeded have been brought to grade, and immediately prior to dumping and spreading of topsoil, the subgrade shall be loosened by disking or by scarifying to a depth of at least 2-inches to permit bonding of the topsoil to the subsoil.

3.

It is imperative that topsoil be of high quality as the basis of the project is the establishment of seedbed conditions conducive to maintaining permanent vegetative cover. Topsoil shall be a sandy loam, clay loam, sandy clay loam, or other soil approved by the Contracting Officer. For topsoil to be considered loamy, that fraction passing the No. 10 sieve shall not contain more than 40% clay. Acceptable topsoil shall not contain less than 3% or more than 20% organic matter.

4.

Topsoil shall not be a mixture of subsoil and or contain slag, cinders, stones, lumps of soil, sticks, roots, trash, or other extraneous material larger than 1½-inches in diameter.

5.

The topsoil shall be uniformly distributed on designated areas. Topsoil shall not be placed while in a frozen or muddy condition or when the subgrade is excessively wet. Any irregularities in the surface resulting from adding topsoil shall be corrected in order to prevent the formation of depressions.

C. Fertilizer:

1. Fertilizer shall be a regular commercial fertilizer, meeting the requirements of applicable state laws. All fertilizer applications for seeding shall be of a 12-12-12 analysis and applied at a rate of 10 pounds per 1,000 square feet of surface area.

2. The Contracting Officer shall be notified in writing or by telephone prior to initiation of fertilizing activities.

3. Fertilizer shall be spread uniformly and worked into the soil immediately after spreading to a depth of not less than 2-inches.

4. If the fertilizer has been washed or otherwise lost from the seedbed through Contractor's neglect, the area so depleted shall be retreated as directed by the Contracting Officer at no cost to the Government.

D. Seeding:

1.

All grading and shaping operations shall be completed and the area to be seeded shall be reasonably smooth, free of hills and gullies before seedbed preparation. The Contracting Officer shall approve the seedbed and be notified in writing or by telephone prior to initiation of seeding.

2.

The area shall be disked and harrowed to a suitable seedbed. A perfectly smooth surface should be avoided. All areas to be seeded shall be free of rock and other foreign material larger than 1½-inches in any dimension. If the seedbed becomes compacted prior to seeding, it shall be re-disked or loosened to a friable condition before seeding.

3.

Seed shall be drilled, hydroseeded, or broadcast with types of equipment approved by the Contracting Officer that shall ensure uniform distribution of seed. Seed shall be placed into soil not less than ¼-inch and not more than ½-inch.

4.

Seeding shall be done as soon as possible after seedbed preparations. Permanent seeding shall be completed prior to October 1. No dormant seeding shall be permitted.

5. Seeding supplied by BesTurf Sod Farms, 2092 Mt. Pleasant St. NW, North Canton, OH, 1-800-927-2105 or approved equal. The following seed mix shall be sown at the rate recommended by the manufacturer:

25% Kentucky Bluegrass 98/85

25% Creeping Red Fescue

20% Chatham Perennial Ryegrass

15% Pearl Perennial Ryegrass

10% Gettysburg Perennial Ryegrass

6. The Contracting Officer reserves the right to test, reject, or approve all seed after delivery on the project.

7. All seeded areas to have at least 75% vegetative coverage to bind soils and prevent erosion and sedimentation. The Contractor shall maintain all seeded and mulched areas until final inspection.

8. Seeded or mulched areas damaged by wind, water, or other causes shall be repaired to the re-established condition prior to seeding as directed by the Contracting Officer. The repairs shall be made prior to completion of the project by re-grading, re-fertilizing, re-seeding, and mulching. All damage or erosion of these areas due to Contractor's neglect shall be satisfactorily repaired at no additional cost to the Government.

9. Any areas outside the construction site where existing vegetation is removed or damaged by the Contractor in the course of this contract shall be seeded, fertilized, and mulched according to these provisions and specifications. This work shall be done at no additional cost to the Government.

E. Mulch:

1.

Within 24 hours after seeding, any seeded area not having erosions matting shall be uniformly mulched at a rate of two (2) tons per acre of clean, un-weathered straw.

2.

Mulching which is displaced shall be replaced at once, but only after the seeding or other work which preceded the mulching and which work was damaged as a result of displacement of mulching materials has been acceptably repaired. This work shall be done at no additional cost to the Government.
