3、 slag coarse and fine aggregates shall be usedentirely (Note 1) or combined with other mineral aggregatescovered in Specification D 692 or D 1073, to produce pavingmixtures as described in Specification D 3515 or D 4215.NOTE 1When 100 % of the coarse aggregate in a bituminous mixtureis steel slag, t

15、cification are defined inTerminologies C 125 and D 8.4. Ordering Information4.1 Orders for the material under this specification shallinclude the following information:4.1.1 The name of material (steel slag coarse aggregateand/or steel slag fine aggregate).4.1.2 The specification designation and yea
16、r of issue.4.1.3 The grading of the aggregate to be furnished, byreference to a size number in Classification D 448 for coarseaggregate, grading number in Specification D 1073 for fineaggregate, or other grading as specified by the purchaser.4.1.4 The quantity required.4.1.5 For coarse aggregate, wh
17、ether the intended use is forconventional mixtures or open-graded friction course mixtures(see 6.1.2), and whether for surface courses or base courses(see 6.1.3).4.1.6 For sulfate soundness tests, which salt is to be used inTest Method C 88 and whether soundness requirements areapplicable for the fi
18、ne aggregate.4.1.7 Any special requirements.5. General Characteristics5.1 The coarse and fine aggregates shall consist of hard,tough, durable pieces of steel slag as defined in 3.1.1. Theaggregates shall be processed, as necessary to meet therequirements of this specification, by crushing or screeni
19、ng, orboth, and magnetic separation for the removal of metallics. Atthe time of delivery, the aggregates shall be free of injuriousamounts of foreign materials such as clay, loam, wood, trampmetal, unhydrated lime and other mill wastes.6. Physical Requirements6.1 Coarse Aggregate:6.1.1 GradingThe co
20、arse aggregate grading shall con-form to the requirements of Classification D 448 for the sizenumber designated, or to another grading as stated in the order(Note 2).NOTE 2The coarse aggregate grading to be furnished is dependentupon the desired composition of the paving mixture, and whether thegrad
21、ing to be used in the mixture is achieved with or without blending.Other coarse aggregate gradings may be used provided that the combinedaggregates and filler, when used, will produce a paving mixture thatprovides the desired characteristics.6.1.1.1 The size to be used is dependent upon the desiredc
22、omposition of the paving mixture, and the required size orsizes either before or after blending as specified.6.1.2 Crushed Pieces in AggregateOrders for materialunder this specification shall state the appropriate requirementsfor percentage of crushed pieces (Test Method D 5821).6.1.2.1 Conventional
23、 mixtures, not less than 40 % by mass,of the pieces retained on the 4.75-mm (No. 4) sieve shall haveat least one fractured face (Notes 3 and 4).6.1.2.2 Open graded friction course mixtures, of the aggre-gate pieces retained on the 4.75-mm (No. 4) sieve, not less than90 % by mass, shall have one or m
24、ore fractured faces and 75 %by mass, two or more fractured faces.NOTE 3Attention is called to the distinction between conventional(dense mixtures or open mixtures) and open-graded friction coursemixtures in Specification D 3515.NOTE 4Some sources of aggregate contain angular particles that willperfo
25、rm similarly to a mechanically crushed particle. Where laboratorytests or service records indicate this to be true, such angular particles maybe considered as crushed.6.1.3 Polishing CharacteristicsThe coarse aggregates, orthe coarsest fraction of the aggregate for use in surface coursemixtures, sha
26、ll be of a type known to possess adequateresistance to polishing action of the anticipated traffic (Note 5).NOTE 5No ASTM standard has been recognized to be capable ofdefining adequate resistance to the polishing action of specific trafficconditions. Test Method D 3319 has been found useful in evalu
27、ating therelative polish resistance between samples of different aggregates ormixtures containing different aggregates.6.1.4 SoundnessThe coarse aggregate, when subjected tofive cycles of the soundness test (see Test Method C 88), shallhave a mass loss not greater than 12 % when sodium sulfate isuse
28、d or 18 % when magnesium sulfate is used. If the salt is notdesignated by the purchaser, the aggregate shall be acceptableif it meets the indicated limit for either salt used.6.1.5 DegradationAggregate subjected to testing in ac-cordance with Test Method C 131 shall have a loss not greaterthan 40 %
29、for surface courses or 50 % for base courses.6.2 Fine Aggregate:6.2.1 The fine aggregate grading shall conform to therequirements of Specification D 1073 for the size numberdesignated, or to another grading as designated in the order(Note 6).NOTE 6The fine aggregate grading to be furnished is depend
30、ent uponthe desired composition of the paving mixture, and whether the grading tobe used in the mixture is achieved with or without blending. Other fineaggregate gradings may be used provided that the combined aggregatesand filler, when used, will produce a paving mixture that provides thedesired ch
31、aracteristics.6.2.2 The size to be used is dependent upon the desiredcomposition of the paving mixture, and the required size orsizes either before or after blending as specified.6.2.3 Grading VariabilityFor continuing shipments offine aggregate from a given source, the fineness modulus shallnot var
32、y more than 0.25 from the base fineness modulus (Note7). The base fineness modulus shall be that value that is typicalof the source. The base fineness modulus shall not be changedexcept when approved by the purchaser.6.2.3.1 The base fineness modulus shall be determined fromprevious tests, or if no
33、previous tests exist, from the average ofthe fineness modulus values for the first ten samples (or allpreceding samples if less than ten) on the order.NOTE 7Base fineness modulus of the fine aggregate has a greatinfluence on proportioning of bituminous mixtures; therefore, largechanges in its value
34、may make adjustments in the mixture necessary.6.2.4 Plasticity index of the fine aggregate fraction smallerthan the 425m (No. 40) sieve shall not exceed 4.0 (TestMethod D 4318).6.3 General Requirements:6.3.1 ExpansionAggregates that contain components sub-ject to hydration shall be obtained from sou
35、rces approved byD5106032the purchaser on the basis of either satisfactory performancerecord, aging, or other treatment known to reduce potentialexpansion to a satisfactory level (Note 8).NOTE 8Test Method D 4792 has been used to evaluate the potentialfor expansion of dense graded materials only.6.3.
36、2 Environmental StabilityAggregates shall be evalu-ated for environmental considerations (air quality, water qual-ity, and storage) using the required local, state, and federal testmethods in effect at the time of use.6.3.2.1 The aggregate shall meet all applicable local, state,and federal environme
37、ntal requirements in effect at the time ofuse.6.3.2.2 Aggregates that exhibit a potential for producingleachates shall be tested using the Toxicity CharacteristicLeaching Procedure (EPA Method SW846 1311) or appropri-ate test method as approved by the purchaser. Results shallindicate that all areas
38、tested (metals, volatiles, semi-volatiles,and organics) are below regulatory limits.6.3.3 Special RequirementsEvaluation will be requiredfor the following items (but not exclusive of) when specified bythe purchaser: the potential for stripping (Test Method D 4867/D 4867M) and friable particles (Test
