16、Method, Toxicity CharacteristicLeaching Procedure43. Terminology3.1 DefinitionsFor defining aggregate types, see Descrip-tive Nomenclature C294 and Terminologies C125 and D8.4. Ordering Information4.1 Orders for the material under this specification shallinclude the following information:4.1.1 The s

17、pecification designation and year of issue,4.1.2 The size number as given in Classification D448 orgrading to be furnished,4.1.3 The quantity required,4.1.4 Use of the coarse aggregate, whether for conventionalmixtures or open-graded friction course mixtures (see 5.3 and5.4), and whether for surface

18、 courses or base courses,4.1.5 In case of sulfate soundness tests, which salt is to beused,4.1.6 Any angularity requirements, and4.1.7 Any special requirements.5. Physical Properties5.1 GeneralThe coarse aggregate shall consist of hard,strong, durable pieces, free of adherent coatings and conform-in

19、g to the requirements of this specification.5.2 GradingThe grading shall conform to one of thefollowing subparagraphs:5.2.1 The coarse aggregate grading shall conform to therequirements of Classification D448 for the size numberdesignated in the order. The size to be used is dependent uponthe desire

20、d composition of the paving mixture, and the requiredsize or sizes either before or after blending as specified.5.2.2 The coarse aggregate grading shall conform to thegrading as specified in the purchase order. The grading to beused is dependent upon the desired composition of the pavingmixture and

21、shall be determined by the purchaser.5.3 Crushed Pieces in AggregateOrders for material un-der this specification shall state the appropriate requirementsfor percentage of crushed pieces.5.3.1 Conventional Mixtures, not less than 40 %, by mass,of the pieces retained on the 4.75-mm (No. 4) sieve shal

22、l haveat least one fractured face. (see Note 2 and Note 3)5.3.2 OpenGraded 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 more fractured faces and notless than 75 %, by mass shall have two or more fractured face

23、s.NOTE 2Attention is called to the distinction between conventional(dense mixtures or open mixtures) and open-graded friction coursemixtures in Specification D3515.NOTE 3Some sources of aggregate contain angular particles that willperform similarly to a mechanically crushed particle. Where laborator

24、ytests or service records indicate this to be true, such angular particles maybe considered as crushed.5.4 Polishing CharacteristicsThe coarse aggregates, orthe coarsest fraction of the aggregate for use in surface coursemixtures, shall be of a type known to possess adequateresistance to polishing a

25、ction of the anticipated traffic (see Note4).NOTE 4No ASTM test method has been recognized to be capable ofdefining adequate resistance to the polishing action of specific trafficconditions. Test Method D3319 has been found useful in evaluating therelative polish resistance between samples of differ

26、ent aggregates ormixtures containing different aggregates.5.5 SoundnessThe coarse aggregate, when subjected tofive cycles of the soundness test, shall have a weighted loss notgreater than 12 % when sodium sulfate is used or 18 % whenmagnesium sulfate is used (see Note 5). If the salt is notdesignate

27、d by the purchaser, the aggregate shall be consideredto be in compliance with this specification if it meets theindicated limit for either salt used.5.6 DegradationAggregate subjected to testing in accor-dance with Test Method C131 shall have a loss not greater than40 % for surface courses or 50 % f

28、or base courses (see Note 5).NOTE 5Coarse aggregate failing to meet the requirements of 5.5 or5.6 may be considered for use provided that (1) similar aggregates fromthe same source have been shown by experience, to the satisfaction of thepurchaser, to result in satisfactory pavement and (2) the resu

29、lts of othertests indicate that the desired performance can be obtained. Aggregatefrom a new source that fails the requirements of 5.5 or 5.6 and for whichno experience exists, may be considered acceptable provided the results ofthe other relevant laboratory tests indicate that the desired performan

30、cecan be obtained.5.7 ExpansionAggregates that contain components sub-ject to hydration shall be obtained from sources approved bythe purchaser on the basis of either satisfactory performancerecord, aging, or other treatment known to reduce potentialexpansion to a satisfactory level (see Note 6).NOT

31、E 6Test Method D4792 has been used to evaluate the potential forexpansion of dense graded materials.5.8 Environmental StabilityAggregates shall be evaluatedfor environmental considerations (air quality, water quality,and storage) using the required local, state, and federal testmethods in effect at

32、the time of use.5.8.1 Aggregates that exhibit a potential for producingleachates shall be tested using the Toxicity CharacteristicLeaching Procedure (EPAMethod SW846 1311) or appropriatetest method as approved by the purchaser. Results shallindicate that all areas tested (metals, volatiles, semivola

33、tiles,and organics) are below regulatory limits.5.8.2 The aggregate shall meet all applicable local, state,and federal environmental requirements in effect at the time ofuse.5.9 Special RequirementsEvaluation will be required, butnot exclusive of, the following items, when specified by thepurchaser:
