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 Fractured Particles in Coarse AggregateOrders formaterial under this specification shall state the appropriaterequirements for percentage of fractured particles.5.3.1 Conventional Mixtures, not less than 40 %, by mass,of the aggregate particles retained on th
22、e 4.75-mm (No. 4)sieve shall have at least one fractured face (see Note 2 and Note3).5.3.2 OpenGraded Friction Course Mixtures, of the aggre-gate particles retained on the 4.75-mm (No. 4) sieve, not lessthan 90 %, by mass, shall have one or more fractured faces andnot less than 75 %, by mass shall h
23、ave two or more fracturedfaces.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 frac
24、tured particle. Where laboratorytests or service records indicate this to be true, such angular particles maybe considered as fractured.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
25、adequateresistance to polishing action 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 res
26、istance between samples of different 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 Not
27、e 5). If the salt is notdesignated 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 than4
28、0 % for surface courses or 50 % for 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 satis
29、factory pavement and (2) the results 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 in
30、dicate that the desired performancecan 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 sa
31、tisfactory level (see Note 6).NOTE 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
32、federal testmethods in effect at 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 te
33、sted (metals, volatiles, semivolatiles,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.4Available from Department of Commerce, National Technical InformationCenter, 5285 Port Royal
