2. PRODUCTS.

2.1 MATERIALS.

2.1.1 General. Riprap material shall be durable quarried stone of suitable quality to ensure permanence in the

Upper Mississippi River environment. Stone shall be free from cracks, seams and other defects that would unduly increase its deterioration from natural causes. A crack is considered to be detrimental if it is more than four (4) mils wide and is continuous for one-third the dimension of at least two sides of the stone.

2.1.2 Specific Gravity. All Stone shall have a specific gravity of not less than 2.55 and not more than 2.75.

2.1.3 Riprap Shape. Neither the breadth nor thickness of any individual stone shall be less than one-third its length.

2.1.4 Riprap Gradation. Riprap shall be reasonably well graded within the specified limits shown on the riprap gradation curve contained in Attachment 4 to permit construction of relatively dense riprap sections. Inclusion of objectionable quantities of dirt, sand, clay, rock fines, or other deleterious materials will not be allowed or measured for payment.

2.1.5 Riprap Gradation Processing. On the same date the Contractor provides the submittal for material sources, the Contractor shall also submit for approval the method of processing riprap at the quarry that will preclude the inclusion of objectionable amounts of fine material and organic matter. All riprap shall be processed in accordance with the approved method. Quarry-run riprap material will not be accepted. All rock designated for use as riprap shall be processed over a vibratory grizzly or by an approved method to insure the exclusion of poor quality rock.

2.2 SOURCES AND EVALUATION.

2.2.1 Approved material sources are provided in Attachment 2. The Contractor may elect to furnish rock from another source(s) not listed in Attachment 2, provided the source is approved by the Contracting Officer and meets the conditions hereinafter stated. If the Contractor proposes to furnish materials from a source not listed, the Government Geologist will make such investigations and evaluations as necessary to determine whether or not materials meeting the requirements of this contract can be produced from the proposed source. The Contractor shall be responsible for making its own investigations for sources of suitable materials and for making its own arrangements with the owners of the quarries or land for procuring the required quantities of suitable materials.

2.2.1.1 Within 7 calendar days after award of the contract, the Contractor shall designate and submit for approval only one source or combination of sources from which it proposes to furnish the materials specified. If the Contractor proposes to furnish materials from a source or from sources not listed in Attachment 2, it may designate only a single source or a single combination of sources from which to furnish the material specified. Samples for acceptability testing shall be provided as required by the PARAGRAPH: 2.3 Tests for Acceptability of Alternative Source Material. If a source for materials so designated by the Contractor is not approved for use by the Contacting Officer, the Contractor shall not submit for approval other sources but shall furnish the materials from approved sources selected from the list in Attachment 2, at no additional cost to the Government.

2.2.1.2 Approval of a source of material is not to be construed as approval of all material from that source. The right is reserved by the Government to reject materials from certain localized areas, zones, strata, or channels when such material are unsuitable as determined by the Government Geologist. Materials produced from an approved source shall meet all of the requirements of this specification.

2.2.2 No riprap material shall be used from any river facing bluffs that are visible from the Mississippi

River.

2.3 TESTS FOR ACCEPTABILITY OF ALTERNATIVE SOURCE MATERIAL.

2.3.1 Quality tests and service records will be used to determine the acceptability of stone materials. In the event suitable test reports and satisfactory service records are not available, as in the case of newly operated sources, the materials will be tested to determine acceptability. Tests to which the materials may be subjected to include petrographic analysis, specific gravity, soundness, abrasion, absorption, freezing and thawing, and other tests considered necessary to demonstrate acceptability. Tests will be made by, or under the supervision of, the Government and at the Government’s expense.

2.3.2 Samples. When directed by the Contracting Officer, suitable samples of materials shall be submitted for approval prior to delivery of materials to the work site. Samples shall be obtained by the Contractor, in the presence of the Contracting Officer or its designated representative, and delivered at the Contractor’s expense to a point designated by the Contracting Officer, at least 15 calendar days in advance of the date that the material is required to be delivered.

2.4 RIPRAP GRADATION TESTING.

2.4.1 General Requirements. Gradation tests shall be performed by the methods and frequency listed below.

Testing listed herein shall be completed by and at the expense of the Contractor. Gradation testing results shall be submitted utilizing the gradation plots for the required riprap gradation and the WORKSHEET FOR GRADATION ANALYSIS OF RIPRAP (gradation plots and blank copies of the worksheet are included in the attachments section). The Contracting Officer shall direct the time and location of sampling, unless waived. The Contracting Officer shall be informed a minimum of 24 hours before each test is to be performed. The results of all tests, including failing tests shall be submitted on the appropriate gradation plots and worksheets. The Contracting Officer shall be informed immediately of test results and draft copies of test results shall be submitted at the Contracting Officers request. Tests performed on material that does not meet gradation and shape requirements will not be counted as part of the tests required.

2.4.2 Test Method A. Test method A shall consist of weighing all stones larger than 5 pounds in a sample.

Five to seven weight classes shall be selected within the range of stone sizes. Each stone shall be weighed and recorded on the worksheet for method A. The weight of stones shall be summed for each weight class; after which calculations and a plot of the gradation shall be completed in accordance with accepted practice for soil and aggregate gradations.

2.4.3 Test Method B. Test method B shall consist of separating the stones into 5 to 7 piles, ordered by size.

The sample shall be separated on a clean, hard surface that is free of smaller stones that could become mixed with the sample. The stones shall be visually screened to place them into appropriate piles. All stones shall be separated and placed into a pile before weighing. After separating, the smallest and the largest rock in each pile shall be weighed and recorded. The stones shall be adjusted as necessary so that the weight classes do not overlap. After adjustment is adequate and weight classes have been established, each pile of stone shall be weighed and recorded on the worksheet for method B.

Calculations and a plot of the gradation shall be completed in accordance with accepted practice for soil and aggregate gradations.

2.4.4 Scales. Accuracy of scales shall be as required in PARAGRAPH: 1.4.1 Measurement.

2.4.5 Testing. A sample shall be obtained from each approved material source or combination of sources for each gradation required and tested in accordance with either method A or B. A satisfactory test shall be obtained from each source or combination of sources for each gradation prior to hauling any riprap from that quarry. Each sample shall have a minimum gross weight of not less than 25 times the maximum stone size in the specified gradation (25∙W100).

2.4.6 Testing Frequency. Gradation tests will be required at a frequency of 1 per 5,000 tons of each gradation of material from a specific source that is brought on site, with a minimum of one test per gradation. Tests that do not meet gradation requirements will not be counted.

2.4.7 Corrective Action. If materials fail to meet gradation or shape requirements, the Contractor shall adjust its operations and verify with necessary tests that acceptable materials are being produced, or it shall propose another source and verify, with necessary tests, that acceptable material can be produced from that source.
