15、States.3.1.2 Other terms used in this specification are defined inTerminologies C 125 and D8.4. 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

16、.2 The specification designation and year 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

17、 required.4.1.5 For coarse aggregate, whether 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 C88 and whether soundnes

18、s requirements areapplicable for the fine 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 thi

19、s specification, by crushing or screening, orboth, and magnetic separation for the removal of metallics. Atthe time of delivery, the aggregates shall not contain injuriousamounts of foreign materials such as clay, loam, wood, trampmetal, unhydrated lime, or other deleterious materials.6. Physical Re

20、quirements6.1 Coarse Aggregate:6.1.1 GradingThe coarse 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 comp

21、osition of the paving mixture, and whether thegrading 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

22、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.6.1.2 Crushed Pieces in AggregateOrders for materialunder this specification shall state the appropriate requirementsfor percentage of crushe

23、d pieces (Test Method D 5821).6.1.2.1 Conventional 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) sie

24、ve, not less than90 % by mass, shall have one or more 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

25、aggregate contain angular particles that willperform 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 th

26、e aggregate for use in surface coursemixtures, shall 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.

27、 Test Method D 3319 has been found useful in evaluating 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 C88), shallhave a mass los

28、s not greater than 12 % when sodium sulfate isused 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 Met

29、hod C 131 shall have a loss not greaterthan 40 % 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

30、 fine aggregate grading to be furnished is dependent 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 pro

31、duce a paving mixture that provides thedesired characteristics.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

32、a given source, the fineness modulus shallnot vary 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

33、shall be determined fromprevious tests, or if no 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 bituminou

34、s mixtures; therefore, largechanges in its value 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

35、 sub-ject to hydration, such as free-lime (CaO), shall be obtainedD5106082from sources approved by the purchaser on the basis of eithersatisfactory performance record, aging, or other treatmentknown to reduce potential expansion to a satisfactory level(Note 8).NOTE 8Test Method D 4792 is used to eva

36、luate the potential forexpansion of dense graded materials only.6.3.2 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 ag

37、gregate shall meet all applicable local, state,and federal environmental 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

38、 as approved by the purchaser. Results shallindicate that all areas 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 fo
