B. Markings shall not be permanent and must be removed after government verification.

1.4 QUALITY ASSURANCE

A. Regulatory agencies, codes & standards

All work shall be performed in accordance with all applicable Local, State or Federal regulations and requirements, including Occupational Safety standards. The Contractor shall be responsible for verifying that required permits are secured and approved prior to starting any work affected by such requirements.

B. Soil testing and inspection

Contractor shall provide soil testing and quality control testing during earthwork operations from an independent testing entity acceptable to both the Government and the Contractor. The cost of all testing shall be borne by the Contractor. Contractor shall obtain and submit to the Contracting Officer the test results for every soil proposed to meet specified material or to be used within the project, prior to such material being used on the project. These tests shall include:

a. Optimum moisture-density curve as determined by ASTM D 1557 (modified proctor)

b. Sieve analysis as determined by ASTM C-117 & C-136

c. In addition to initial testing, Contractor shall perform additional gradation tests and furnish results as materials are processed and/or delivered. Frequency of

31 20 00 - 2 additional testing shall be 1 test per 500 cubic yards. If source of materials should change after completion of original test, a complete set of tests, as required above, shall be performed again.

d. The Government reserves the right to conduct quality control inspection and testing to determine the reliability of the test results.

e. Materials delivered that do not comply with the specifications and/or certifications shall be removed from the site at no cost to the Government.

1.5 SUBMITTALS

A. Comply with Section 01330 (Submittals) with regard to process and quantity of submittals.

B. Submittals shall be prepared for items including, but not limited to:

1. Soil gradations

2. Soil density tests (modified proctors)

1.6 PROTECTION OF PERSONS AND PROPERTY

A. The Contractor shall be responsible to ensure that all persons and property are adequately protected. The public, structures, utilities, traffic, sidewalks, pavements and other facilities shall be protected from damage caused by settlement, lateral movement, undermining, washout and any other hazard created by the earthwork operations. Protect all existing trees, shrubs and plantings.

PART 2 - PRODUCTS

2.1 MATERIALS

A. Crushed Stone Aggregate Surface Course Material (Half Inch Minus)

1. Aggregate shall consist of hard, durable particles or fragments of crushed stone or gravel conforming to the following requirements and gradations:

Los Angles abrasion, ASTM C 131 and C 535 ................ 50% max.* Fractured faces (one face) ................................................ 95% min.* Fracture faces (two faces) ................................................ 75% min.* Soundness loss, 5 cycles, ASTM C 88 (magnesium) ....... 18% max.* Flat/Elongated (length to width >5 ASTM D4791 .......... 15% max.*

* Based on the portion retained on the 3/8" sieve

2. Materials shall be free from organic material and lumps or balls of clay.

3. Material passing the No. 4 sieve shall consist of natural or crushed sand and fine mineral particles. The material including any blended filler, shall have a plasticity index of not

31 20 00 - 3 more than 6 and a liquid limit of not more than 25 when tested in accordance with ASTM D4318.

4. Aggregate shall contain a minimum of 5% clay particles by no more than 50% of that portion of material passing the No. 200 sieve size shall be clay. Inorganic clay to be used as binder shall conform to the following:

Passing No. 200 ......................... 75% Liquid Limit ........................... 30 min.

Plastic Index ............................. 8 min.

5. The fraction of material passing the No. 200 sieve size shall be determined by washing as indicated in ASTM D1140, "Amount of Material in Soils Finer Than the No. 200 Sieve."

The fractured faces for the coarse aggregate portion (retained on the No. 4 Sieve) shall have an area of each face equal to at least 75% of the smallest midsectional area of the piece. When two fractured faces are contiguous, the angle between the planes of fractures shall be at least 30 degrees to count as two fractured faces. Fractured faces shall be obtained by mechanical crushing.

6. Gradation shall be obtained by crushing, screening, and blending processes as may be necessary. Material shall meet following screen analysis requirements by weight.

Sieve Designation Percent Passing 1/2" 100% 3/8” 90-100% No. 4 60-81% No. 8 44-60% No. 40 20-33% No. 200 10-16%

PART 3 - EXECUTION

3.1 AGGREGATE EMPLACEMENT

B. The contractor will be responsible for measuring existing surface course in advance of the placement, determining emplacement thickness, assuring that a uniform thickness has been emplaced and compacted to specifications, that the road profile has been maintained.

C. The standard for depth shall be to approach 2 inches of surface course depth without going under.

D. Sections over 100’ long that consistently have depths under 2 inches or over 2.5 inches, or do not have an evenly graded surface, or do not have sufficient compaction, will be required to be reworked.

E. Placement will be in accordance with the approved quality control plan.
