2. MATERIALS REQUIRED:

Acceptance of Materials: Materials will be inspected at the jobsite prior to acceptance/delivery. Contractor shall be responsible for maintaining gradation as specified. Materials test requirements maybe required if on site Corps of Engineers representative determines that materials being delivered does not meet the specification contained in this document.

3. METHOD OF DELIVERY:

All materials will be delivered using Solo Truck, Truck and Transfer or Side Dump; Supplier must be able to provide a minimum of 1000 tons of material per day.

4. STONE MATERIALS SPECIFICATIONS:

Each stone piece shall meet the following test requirements for quality:

Test Requirement

Specific Gravity (BSSD) 2.60 minimum.

(ASTM C127-88(2001) (CRD-C 107)

Absorption Not more than 3 percent

(ASTM C127-88(2001) (CRD-C 107)

Abrasion Not more than 20 percent loss

(ASTM C131-96) (CRD-C 117)

Accelerated Expansion (CRD-C 148) Not more than 10 percent breakdown

Magnesium Sulfate Soundness, 5 cycles (ASTM C88-99a) (CRD-C 137) Not more than 10 percent loss

Drop Test No breakage or cracking

5. LABORATORY STONE TESTING:

Previous test results may be requested to verify quality. The following represent test procedures specified recently on Corps projects to determine quality:

a) Specific Gravity and Absorption: Weight per cubic foot will be determined by multiplying the bulk-saturated-surface-dry specific gravity (BSSD) times 62.4 pounds per cubic foot. Specific gravity and absorption will be determined in accordance with ASTM C127 (Corps of Engineers Testing Procedure CRD-C 107), modified as follows: The test sample will consist of about 5,000 grams of generally cubical pieces of stone passing the 2-inch and retained on the 1-1/2 inch standard square mesh sieve sizes. Test pieces will be laboratory prepared by jaw crushing and chipping. Test method permits a variance in reproduction of test results of 0.02 in BSSD specific gravity and 0.05 percent in percentage of absorption. This variance in specific gravity is equivalent to a variance of plus-or-minus 1.2 pounds per cubic foot in unit weights computed from the specific gravity.

b) Abrasion: Abrasion loss will be determined in accordance with ASTM C131 (Corps of Engineers Testing Procedure CRD-C 117), modified as follows: Test sample will be of the same size and gradation as that described above for use in determination of specific gravity and absorption, the abrasive charge used will comply with that used in Grading “A", and the test sample will be subjected to 500 revolutions.

The standard test method designated ASTM C535 (CRD-C 145) shall not be substituted for ASTM C131.

c) Accelerated Expansion (15 Days): The test sample will be tested in accordance with Corps of Engineers

Testing Procedure CRD-C 148, except as herein specified. Testing procedure for sample size in CRD-C 148 will be modified as follows: The test sample will be from 4,950 grams (10.83 pounds) to 5,050 grams (11.05 pounds) of 1-1/2 inch to 2 inch pieces. Test results will be computed by dividing the number of pieces that breakdown by the number of pieces in the original test sample. Failure or breakdown is defined as any piece separating into two or more pieces or losing sufficient surface material to allow it to pass through the 1-112 inch sieve. Maximum allowable breakdown is 10 percent over a period of 15 days. Weight loss based on the original oven dry weight will be recorded.

d) Magnesium Sulfate Soundness: The test is based upon ASTM C88 (CRD-C 137). Test sample will be similar to that described above for use in determination of specific gravity and absorption. This test, which will be conducted through five cycles, which requires 2 to 3 weeks time for completion.

e) Physical Stone Testing by Drop Test. A drop test provides an immediate evaluation of the durability of very large stones during handling of the stone including placement into a structure. If requested, several representative test stones shall be dropped from a bucket or by other means from a height of not less than half the average diameter of the stone onto a rigid surface or second stone of comparable size. Dumping from a truck is not acceptable. The stone shall be examined carefully before as well as after the completion of the test. Failure criteria are the development of new cracks, opening of old cracks, and the loss of a piece from the surface of the stone. Each stone that is to be tested shall be dropped a total of five times for evaluation purposes with examination after each drop. The Contractor shall provide all necessary equipment and operating personnel to help perform the testing. Drop tests shall be conducted by the Contractor under the supervision of the Contracting Officer.

f) Quarry Operations. Quarry operations shall be conducted by the Contractor in a manner that shall produce stone conforming to the requirements specified and may involve selected quarrying, handling, processing, blending, and loading as necessary. Blasting and handling of rock shall be controlled by the Contractor to produce rock of the size ranges and quality specified. Techniques such as the use of proper hole diameter, hole depth, hole angle, burden, and spacing distances, types and distribution of explosives, delay intervals and sequence, removal of muck piles between each shot, and special handling techniques are required as necessary to produce the specified materials. All aspects of blasting operations shall be specifically designed so that the end product is not damaged from the blasting technique and that the stone is suitable for the intended purpose.

g) Stone Gradation:

Stone shall be 2-4 Ton Rock as specified below:

Distribution Weight (lbs) Diameter (Inches) 100% Smaller 8000 52-66

50% Size 6000 38-52 100% Larger 4000 22-30

Sieve Percent Passing 4 inch 100 2 inch 0

All rock shall be sound, clean, angular, durable stone. Rounded rocks are not acceptable. The longest dimension of any stone shall not exceed three times its shortest dimension. Acceptability of stones will be determined by visual inspection, laboratory tests, and/or geologic inspection.

Topsoil The topsoil for the project will consist of a 75/25 mixture of engineered soil and organic compost, respectively. The engineered soil will meet the following gradation, and shall be free of roots, chemicals, garbage, and debris.
