(See D6825 for further information.)3.2.2 slab piecespieces of riprap that exhibit dimensional ratios of the thickness to width or width to length, or both, in excessof a specified ratio. The specified ratios typically range from 1:4 to 1:3 or less.4. Summary of Test Method4.1 The fol
21、lowing four test methods for evaluating particle size distribution are available: Methods A and B involve weightingthe material, determining the mass of the material. Methods C and D involve measuring the sizes. Generally, the precision ishighest for Method A, and consecutively lowest for Method D.
22、The advantages to using different methods depend on resources,sampling frequency and quantity, and to some extent the material size uniformity.4.1.1 Test Method AA sample of the material is obtained, the mass of each individual particle is weighteddetermined andrecorded. Test Method A is the most ri
23、gorous. It is most easily implemented for small sized rock that can be handled manually,or for very limited samples of large pieces.4.1.2 Test Method BAsample of the material is obtained, grouped into weight ranges, and each mass ranges. Each pile withina weight range is weighted.given range has its
24、 mass determined.4.1.3 Test Method CA sample of the material is obtained, the size of each particle is measured and grouped into size ranges,and the size ranges are converted to mass.4.1.4 Test Method DA sample of the material is partitioned within a revetment, particle sizes are measured and groupe
25、d intosize ranges, and the size ranges are converted to mass.5. Significance and Use5.1 Riprap is commonly used to prevent erosion of underlying materials due to the effects of rain runoff, wind, flowing water,or wave action. The particle size distribution (mass of particles) is an important physica
26、l characteristic of riprap, as discussed inGuide D6825. These test methods provide a gradation of the material graphically represented as percent finer than the particlemass. If a gradation can be established or accepted on the basis of only maximum and minimum particle sizes, then it may notbe nece
27、ssary to establish the complete gradation in accordance with these test methods.5.2 These test methods can be used during evaluation of a potential source, as a means of product acceptance, or for assessmentof existing installations. Method D is not recommended as a means of product acceptance.5.3 O
28、ther characteristics of interest, such as particle shape, particle angularity, or visually evident rock durability characteristicsmay be determined during the performance of these test methods.5.4 Interpretation of test results must consider the representativeness of the sample.NOTE 2The agency perf

Reliable testing dependsresults depend on many factors;Practice D3740 provides a means of evaluating some of those factors.6. Apparatus6.1 Scales, of adequate capacity to determine the mass of the sorted riprap pieces either i
32、ndividually or in whole. For TestMethodA(or calibrations for Test Methods B and C), the scale will be accurate to 1 % of the indicated mass. Calibrated or certifiedcommercial truck or quarry scales of adequate capacity are typically used. For individual particle measurements using Test MethodA, hois
33、t line load cells have been used successfully. For Test Method B, the scale will be accurate to 5% of the indicated mass.If bucket scales are used, they shall be subject to calibration and verification with a certified truck scale.6.2 Sieves or Templates, meeting the requirements of Specification E1
34、1 for sizes up to 5 in. (125 mm). For sizes above 5 in.,larger than 5 in. (125 mm), single-opening templates may be fabricated for the required sizes. Templates may be fabricated fromsteel bar or other sufficiently rigid materials in the sizes required. For templates openings from 5 in. to 16 in. (1
35、25 to 400 mm),D5519 142the openings willshall be within62 % of the size, for templates greater than 16 in., in. (400 mm), the openings willshall be within60.25 in. (6.35(6.3 mm). Sieves and templates should be checked on a regular basis to verify squareness, straightness, andconformance to opening t
36、olerances. Hand grips or handles should be considered for ease of use. For larger sizes, it has been founduseful to fabricate templates in the form of a C-shaped caliper representing the sieve opening and the diagonal of the sieve opening(see Fig. 1).6.3 Transport Vehicle, capable of conveying the i
37、ndividual or groups of the individual sorted riprap pieces from the samplingpoint to the test area, and from the test area to the weighing station. If truck scales are used, the transport vehicle should be taredprior to and after determination of the masses.6.3 Handling Equipment, such as forklifts,
38、 loaders, or like equipment forklifts and loaders for sampling, transporting, assistingin the sorting, loading for transport, weighing, and other tasks involved in the physical performance of the test.6.4 Tape Measures for determining particle size dimensions to estimate mass or determine slab piece
39、s.6.6 Test Area, sufficiently large to allow the placement of the test sample, areas or bins to place the sorted materials, andadequate to allow trucks, loaders, and other required equipment to operate safely. The test area should have a smooth surface,preferably of concrete, to provide a suitable w
40、ork surface and prevent loss of the fines.6.5 Proportional Calipers, fabricated in a sufficient size or sizes for use in determining if pieces meet or exceed dimensionalratios to be considered slab pieces (see Fig. 1).6.6 Miscellaneous Equipment, such as spray paints to mark pieces, rock hammers, ca
41、meras for photo photographic or videodocumentation, sample bags, tags or signs, data-recording forms, heavy work gloves, safety goggles or glasses, respirators or dustmasks, and steel-toed boots or caps, as required for the work.7. Hazards7.1 The test facility needs to be adequately large to allow t
42、rucks, loaders, and other required equipment to operate safely duringtest sample placement within areas or bins for sorting by size or mass.7.2 Performance of these test methods includes the moving, lifting, measurement, and transfer of large pieces of rock. Thispresents the potential for personnel
43、injury from crushing, dropped or rolling of the riprap pieces. Whenever possible, the sampleshould be spread to a single layer depth to reduce personnel hazard from rolling or falling pieces.7.3 Personnel performing these test methods will be in the vicinity of working heavy equipment and precaution
44、s should be takento prevent injury from equipment.7.4 Working with and around the pieces may subject personnel to dust, flying particles, falling pieces, and excessive noise.Personnel should be adequately equipped and trained in the use of personal protective equipment.8. Sampling8.1 The precision a
45、nd representativeness of these test methods is directly related to the sampling process. The sampling shouldbe carefully planned and executed to achieve optimum representativeness. All parties Relevant project stakeholders should beinvolved in the planning process. The sampling plan should be docume
46、nted and included as a part of the final report.FIG. 1 Single-Opening Sieve TemplateRiprap Measuring EquipmentD5519 1438.2 The mass of the total test specimen should be large enough to ensure a representative gradation and should be such that itprovides test results to the desired level of accuracy.
47、 One analogy is to consider a test specimen size of such size that the additionor loss of the largest expected piece will not change the results by more than a specified percentage.3NOTE 3Example: For a test specimen size to achieve a 1 % accuracy, assume that the largest individual piece mass is ex
48、pected to be 150 lb (68 kg).For this piece to represent less than 1 %, the sample mass would be 15 000-lb (6 800-kg) minimum. For this piece to represent less than 5 % accuracy,the sample size would be 3000-lb (1360-kg) minimum.8.3 Take an adequate amount of sample to ensure that the minimum test sp
49、ecimen mass is available, however sampling will notbe to a predetermined exact mass. Composite samples will be allowed only when included in the sample plan.8.4 Composite samples are not recommended, since it is more difficult to trace the sample source and the product that the samplerepresents. Composite samples may provide some efficiency for Test Method B; but composite samples provide little advantagein reducing field measurements for Test Methods A and C.8.5 Sampling from the source material will be in accordance with the sampling plan with the emphasis on obta
