PART 2 PRODUCTS

2.1 STONE

2.1.1 General

a. Shape: All stone must be sub-angular to angular quarried material with a shape that assures interlocking with adjacent stone.

b. All stone must be durable material approved in advance. In case an unlisted source is to be used, demonstrate that an adequate quantity of material is available and provide quality test data. Stone must be of a suitable quality to ensure permanence in the structure and in the climate in which it is to be used. Vary the quarrying, processing, loading and placing operations to produce the sizes and quality of stone specified. If the furnished stone does not fully meet all the requirements of these specifications, provide, at no additional cost to the Government, other stone meeting the requirements of these specifications.

c. Stone must be free from cracks, blast fractures, bedding, seams and other defects that would tend to increase its deterioration from natural causes. Inspections for cracks, fractures, seams and defects must be made by visual examination during Contractor Daily Stone Quality Control Inspections.

2.1.2 Stone Sources

2.1.2.1 Stone Source Authorization

a. Before stone is produced from any source, the source of stone must be approved. Submit the name and location of the proposed Stone Source(s) in writing at least 15 days prior to the stone source inspection date.

b. The Government will conduct a stone source investigation and evaluate the quality test data provided by the Contractor to determine whether acceptable stone can be produced from the proposed source. Notify and schedule the stone source inspection and submit stone quality test results. A stone source may be one or a combination of the following types of sources of stone:

(1) Stone source listed within the specifications herein.

35 31 26 - 4

(2) Stone source proposed by the Contractor and not listed within the specifications herein.

c. Authorization of a stone source is not be construed as a waiver of the right of the Government to require the Contractor to furnish stone which complies with these specifications. Materials produced from localized areas, intervals, or strata will be rejected when such materials do not comply with the specifications. Before a proposed source of stone will be considered for evaluation and approval, the Contractor must demonstrate that the source is capable of providing the quality, quantities and gradation needed and at the rate needed to maintain the scheduled progress of the work. If sufficient amounts of stone conforming to these specifications are not available from a source or sources used in the work, the Contractor must submit stone from another source for authorization.

2.1.2.2 Stone Authorization Criteria

Authorization of a proposed stone source will be based on test results and stone source inspection. Government approved stone quality tests are required for all stone sources, as outlined in paragraph, Quality Compliance Sampling and Testing. The Contracting Officer will approve the source based on stone quality, stone source inspection and the stone source demonstration stockpile inspection.

2.1.2.3 Potential Stone Sources

a. On the basis of information and data available to the Government, the following sources located near the project have in the past produced stone meeting the quality requirements of these specifications:

Quarry Name Nearest City

3M Corona Corona, California Pebbly Beach Avalon, California

b. Listing of a stone source is not to be construed as current or future availability of the source, authorization of all materials from the source, nor as a waiver of inspection and testing of the source. Stone produced from any source must meet all the requirements set forth in these specifications. Listing of a stone source is also not to be construed as an indication that the source can produce the total quantity or size of stone required for the project. Stone may be furnished from other sources designated by the Contractor and authorized by the Contracting Officer.

2.1.2.4 Stone Source Inspection

The proposed stone source must be inspected and approved prior to source authorization. The inspection must be performed at the quarry/stone source by the Contracting Officer, Contractor, a materials laboratory technician from the approved laboratory described in paragraph Materials Testing Laboratory, a representative of the quarry, and a Geologist from the Geotechnical Branch, Geology Section, of the Los Angeles District. Provide notification of the stone source inspection to all required attendees a minimum of 15 days prior to the inspection date. The inspection date must be a minimum of 45 days in advance of the time when the stone will be required in the work. During the stone source inspection, the Contracting

35 31 26 - 5

Officer will select the samples to be collected for quality testing in accordance with paragraph Stone Quality.

2.1.3 Stone Quality

2.1.3.1 Quality Compliance Sampling and Testing

a. Collect a minimum of two stone samples from each separate rock-type lithology for each proposed source and perform the complete list of stone quality evaluation tests twice for each separate rock-type lithology.

In addition to the above tests, subject the stone to a petrographic and X-ray diffraction analysis, in accordance with ASTM C295/C295M (5). The stone must not contain any expansive clays.

c. Specific Testing Procedures

(1) Wetting and drying test. Perform this test using all procedures according to ASTM D5313 and in accordance with the following specific procedures:

(a) Entire sample must be carefully examined and four representative test specimen slabs selected and produced. The specimen slabs must be large enough to produce four separate cut slabs, each a minimum of 2-1/4 inches thick, with a minimum total surface area of 25 square inches on the slab side. The slab must not be less than 5 inches length per side.

(b) The test samples must be color photographed four times to show all surface features, before each slab is produced. After the slabs are produced and prior to performing the first cycle of the test, the slabs must be individually photographed to show all surface features and then examined under a low-power microscope of at least 20X magnification. All visible surface features must be noted and recorded. A length scale must be included and shown in all color photographs of slabs.

(c) Subject the slabs to a maximum of thirty cycles of wetting and drying. Two of the four slabs must be soaked in fresh tap water with 0.5 percent ethyl alcohol added by mass; the remaining two slabs must be soaked in salt water, in accordance with ASTM D1141, if a source of nearby natural salt water is not available.

(d) At intervals of every four cycles, the slabs must again be individually color photographed and examined with the low-power microscope to check for openings or movement of fractures, disintegration, spalling, splitting, flaking along edges, swelling

35 31 26 - 8 of clays, softening of rock surfaces, heaving of micaceous minerals, breakdown of matrix material, and any other evidence of weakness developing in the rock. Observation or worsening of any of the aforementioned flaws must be recorded and the cycle at which they are first observed must be included.

(e) After thirty cycles, the slabs and chunks must again be examined, and all changes must be noted and recorded. The test slabs, together with all particles broken-off during the test, must be oven-dried, weighed, and color photographed. The test may be terminated prior to the completion of thirty cycles, if the mass of the largest remaining fragment of the slab amounts to less than half of the mass of the original slab specimen.

(2) Weakening and loss of individual surface particles is permissible, unless bonding of the surface grains softens and causes general disintegration of the surface material.

(3) The test procedure for Petrographic and X-ray Diffraction is performed according to ASTM C295/C295M, except for the following:

(a) Prepare a color, magnified photograph of each stone type using a microscope, and identify the individual minerals within the stone by labels and arrows, upon the photograph.

(b) Develop a very detailed macroscopic and microscopic description of the stone, to include all the mineral constituents, individual sizes, their approximate percentages, and mineralogical histories. Include a description of stone hardness, texture, weathering, and durability factors.

(c) Present a written summary of the suitability of stone for use as stone protection, based on the Petrographic and X-ray tests and the results of ASTM C535, in the final laboratory report on stone quality.

(4) Provide a minimum of two color photographs for each individual stone quality test. Take one of the two photos prior to commencement of each test, and the other after completion of any of each test. Include a suitable length scale in each color photograph. Label each photo "prior to testing" and "after testing" as appropriate. Label each photo with the name of the test and the name of the sample.

(5) Test procedure for LA Abrasion test. Perform this test using all procedures according to ASTM C535, but the following specific procedures for LA Abrasion testing must be performed: The entire sample must be run for 500 revolutions on rock particles in the size range graded from approximately 3 to 4 inches in diameter.

2.1.3.5 Stone Acceptance Criteria

a. All stone is subject to approval. The Contracting Officer will perform visual inspections and measurements of the stone at any point, including before and during delivery to the job site and up to and including placement.

b. If, by visual examination, it is determined that 4 percent or more of the stone produced contains hairline cracks, then all stone produced

35 31 26 - 9 by the means and measures which caused the fractures must be rejected.

Observed deviations of gradation, weight or quality of stone from the specified requirements or stone considered by the Contracting Officer to be questionable will lead to the stone being rejected and re-sampling and re-testing will be required.

(1) Detrimental hairline cracks are defined as being a minimum width of 4 mil (0.1 mm) and are seen continuously running along one-third the dimension of at least two sides of the stone.

c. Additional sampling and testing of the stone, including the type and quantity of sampling, is at the discretion of the Contracting Officer.

Acceptance of any stone does not constitute acceptance of all stone from a source. All accepted stone must be as follows:

(1) Accepted by the Contracting Officer from an authorized source.

(2) Of the same lithology as the original stone from which test results or quarry records were taken as a basis for authorization of the source.

(3) Sound, durable, hard, and free of laminations, weak cleavages, undesirable weathering, or blasting or handling-induced fractures which subtend more than 1/3 of the total circumference of the stone along the plane of fracturing and which would tend to increase its deterioration from natural causes and hairline cracks that are detrimental.

(4) Of such character that the stone will not disintegrate from the action of air, water, or the conditions of handling and placing.

(5) Clean and free from earth, clay, refuse, or adherent coatings.

(6) Meet all the prescribed stone acceptance criteria and pass all stone quality tests.

2.1.3.6 Stone Source Demonstration Stockpile

a. Following submittal of the Contractor's Stone Source Quality Control (QC) Plan and selection of a source, but prior to the Government's approval of a source, make arrangements to provide a pre-production demonstration stockpile for each stone source according to each specific stone gradation class for the project. Submit notification and schedule Government inspection of demonstration stockpile. All stockpiles must be evaluated for quality and gradation by the Contracting Officer. The stockpile will contain 48 stones and must be located at the source of the stone and be shaped in windrow fashion.

b. Place stones with a size range greater than 15 inches in a single layer with 5 foot of clear space around each stone. Turn individual stones as directed to accommodate the Contracting Officers inspection.

Do not stack stones under 15 inches in size higher than 2 feet. All stones placed in the demonstration stockpiles must be representative of the overall quality of materials in the source and should not consist of the best specimens, unless it is reasonable to determine that the source will provide the required amount of stone of the applicable size range with a degree of quality no less than that existent in the demonstration stockpile.

35 31 26 - 10

c. Preselect all stones placed in the stockpile consistent with what is described in the Contractor's QC Plan and:

(1) Eight stones ranging in weight from 4 to 6 tons,

(2) Eight stones ranging in weight from 2 to 4 tons,

(3) Eight stones ranging in weight from 1 to 2 tons,

(4) Ensure that each stone does not exceed the maximum aspect ratio criteria as described in paragraph 2.1.5, Proportional Dimension Limitations.

d. The Contracting Officer will inspect stone in the stockpiles according to the stone quality and gradation criteria of these specifications.

An entire stockpile will be rejected if more than 8 percent of the stones in the stockpile are rejected. If a stockpile is rejected, prepare a replacement stockpile for re-evaluation by the Contracting Officer and revise and resubmit the Stone Source QC Plan. If the replacement stockpile is rejected, the stone source will be rejected for the corresponding size range that is rejected.

e. Stockpiles of representative reject stones from the demonstration stockpile(s) must be marked with a red "X" and set aside to a separate stockpile. The Contractor may choose a replacement stone source if a first or second stockpile is found to be unacceptable. Replacement of the stockpiles or stone sources will be at no additional cost to the Government and with no change in submittal schedule or time of completion of project.

2.1.4 Quarry Operations

a. Conduct quarry operations in a manner that produces stone conforming to the requirements specified. Producing the stone may involve selective quarrying, handling, processing, blending, and loading as necessary.

b. Any stone found to not meet the minimum acceptance criteria as specified in paragraph Stone Acceptance Criteria must be marked with a red "X" and set aside in a stockpile separate from the acceptable stone to be used in the work.

2.1.5 Proportional Dimension Limitations

A flat and elongated piece of stone is defined as having a ratio of width to thickness or length to width greater than 3:1. Use ASTM D4791 as a guide to perform the test. Not more than 20 percent of the stones within a gradation range are to have an aspect ratio greater than 2.5:1 and not more than 5 percent of stones within a gradation class range are to have an aspect ratio greater than 3:1.

2.1.6 Gradation

2.1.6.1 General

a. All new stone must meet the gradation requirements as specified both at the source and as delivered to the project. Stone not meeting the required grading due to segregation or degradation during placement will be rejected. If test results indicate that stone does not meet

35 31 26 - 11 the required gradation, the hauling operation will be stopped immediately and will not resume until processing procedures are adjusted and a gradation test is completed showing gradation requirements are met. All gradation tests are at the expense of the Contractor.

b. New armor stone furnished for repair of the east jetty revetment is designated "A-4 class armor stone". A-4 designation indicates a median stone weight of 4 tons.

2.1.6.2 Gradation Compilation

a. Pr ovi de pr oof of gr adat i on compl i ance by speci f y i ng t he i ndi v i dual wei ght s of each ar mor st one f or each bar ge or t r uck/ l oad.

b. Use scale to weigh each individual stone from each stone gradation class. Add together individual stone weights and obtain total weight from each class. Record individual and total weight for each stone class separately from other stone class types. Submit results in a Stone Gradation Report prior to stone being placed.

c. Measure and determine the greatest and least dimension of each stone larger than 2 tons or 36 inches, if the stone is determined to be elongated, with an aspect ratio of 2 to 1, based on visual estimates.

d. Report the proportional dimension characteristics for each stone weighed that is greater than 2.5 to 1 and 3 to 1 ratios. No more than 20 percent of the total weight of stone per stone gradation class can be greater than 2.5 to 1 ratio. No more than 5 percent of the total weight of stone per gradation class can be greater than a 3 to 1 ratio.

2.1.6.3 Stone Gradation Testing

a. If at any time the Contracting Officer determines that weight determination of the stones is necessary on any barge load or other delivery unit, this action will constitute a formal gradation test.

All formal gradation tests must be at the expense of the Contractor and conducted in accordance with ASTM D5519, Test Method A.

b. Perform a formal gradation testing on samples selected in the presence of the Contracting Officer. Testing may be performed by the Contractor, subject to approval by the Contracting Officer. Testing must be supervised by a California registered Civil Engineer or geologist, experienced in rock gradation testing.

c. Plot the gradation results on gradation curves, all data points representative of the stone must be between the boundary limits, as defined by smooth curves drawn through specified grading limits and plotted on a mechanical analysis diagram. The individual grading curves must not exhibit abrupt changes in slope, denoting skip-grading or scalping of certain sizes. If gradation test results show that stone does not meet the required gradation, the hauling and/or barging and placement operations will be stopped immediately and will not resume until processing procedures are adjusted and a passing gradation test is completed, showing that gradation requirements are

35 31 26 - 12 met.

2.1.6.4 Stone Gradation Reports

Submit Stone Gradation Reports for the initial gradation tests. Submit stone gradation reports following gradation testing performed at the direction of the Contracting Officer. The stone test gradation reports contain the following:

a. Date of test and sample location.

b. Size of sample in pounds and, where applicable, dimensions of the area sampled.

c. The greatest dimension and least dimension, of each stone larger than 36 inches or 2 tons, if the stone is determined to be elongated, with an aspect ratio of 1:1.5 based on visual estimates.

d. Weight of material not measured in c) above.

2.1.6.6 Weight Verification

Provide a visual sample palette of individual stones, each weighing nearest to 6, 4, 2, and 1 tons, that is representative of the weight distribution amongst all of the stone gradation classes required in the specifications. This sample palette must be located on the project site and be visible to aid the Contracting Officer in determining the onsite gradation of stone during continuous Quality Assurance Inspections. Mark each stone with its measured weight in tons such that the marked weight of every stone is clearly visible.

35 31 26 - 13

2.1.7 Rejected Stone

New stone of unsuitable quality and/or size distribution, as required by these specifications, will be rejected. Any rejected stone must be promptly removed from the project at no expense to the Government. Any portions of the work covered by these specifications containing rejected stone will be considered incomplete.

2.2 FILL MATERIAL

2.2.1 General

Provide fill material as needed to construct a temporary ramp/workspace to support equipment operations seaward of the mean higher high water line (MHHW). Use of existing sand on the beach of Corona Del Mar as fill material is prohibited. Following completion of the east jetty revetment armor stone placement, the fill material becomes the property of the Contractor and the top layers must be removed from the site unless the fill material is determined to be beach compatible sand.

2.2.2 Gradation Testing
