1、Designation: D5100/D5100M 95a (Reapproved 2010)1Standard Test Method forAdhesion of Mineral Aggregate to Hot Bitumen1This standard is issued under the fixed designation D5100/D5100M; the number immediately following the designation indicates theyear of original adoption or, in the case of revision,
2、the year of last revision. A number in parentheses indicates the year of lastreapproval. A superscript epsilon () indicates an editorial change since the last revision or reapproval.1NOTEUnits information was corrected editorially in July 2010.1. Scope1.1 This test method determines the adhesion of
3、mineralaggregate when applied over a pour coat of hot bitumen on aroof membrane.1.2 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard. The values stated ineach system may not be exact equivalents; therefore, eachsystem shall be used independently of th
4、e other. Combiningvalues from the two systems may result in non-conformancewith the standard.1.3 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health prac
5、tices and determine the applica-bility of regulatory limitations prior to use.2.

Summary of Test Method4.1 Asmall section of roof surface is fabricated with roofingfelt or membrane usin
7、g measured amounts of a bituminouspour coat and mineral aggregate surfacing. The assembly isallowed to cool, the loose aggregate is removed and weighed,and the mass of adhered aggregate is calculated and reported.5. Significance and Use5.1 The quantities of mineral aggregate adhered to thesurface of
8、 a roof vary with the characteristics and total amountof the aggregate. Mineral aggregate shields bituminous mem-branes from solar radiation. Unadhered mineral aggregate canbe displaced by wind, water, and traffic, exposing the bitumen.5.2 This test method provides a laboratory means of deter-mining
9、 and recording the mass of aggregate that adheres to abituminous pour coat.6. Apparatus6.1 Steel Tray, measuring 143 mm 558 in. 6 1 % squareby 13 mm 0.5 in. 6 10 % in height.6.2 Scales, for weighing bitumen and mineral aggregate,balance 1.00-kg 2.2-lb capacity, sensitive to 0.01 % of thecapacity.6.3
10、 Containers, for hot bitumen and mineral aggregate (1-L1-qt capacity).7. Procedure7.1 Cut a piece of saturated felt to just cover the bottom ofthe steel tray; the saturated felt shall be Type 1 complying withSpecification D226.7.2 Attach the saturated felt to the inside of the tray with athin film o
11、f a release agent such as silicone stopcock grease orpetroleum jelly. Lightly grease the insides of the sides of thetray with the same material.7.3 Weigh out 400 g 0.88 lb of gravel, chert, or trap rock,or 300 g 0.66 lb of slag mineral aggregate surfacing 61%.Record this mass as A. This is equivalen
12、t to 19.5 kg/m2400lb/100 ft2 and 14.6 kg/m2300 lb/100 ft2, respectively.7.4 Apply top pour coat of bitumen uniformly according toquantities and temperatures listed in Table 1.7.5 Immediately apply mineral aggregate into hot bitumenand spread uniformly over entire surface within the tray.Allowthe ass
13、embly to cool for 30 min minimum.7.6 Turn sample upside down and collect loose aggregate.Weigh the loose aggregate and record this mass as B.1This test method is under the jurisdiction ofASTM Committee D08 on Roofingand Waterproofing and is the direct responsibility of Subcommittee D08.03 onSurfacin

Precision and Bias10.1 PrecisionThe precisi
19、on of this test method dependson the characteristics of the mineral aggregate.The precision ofany single test series can be estimated from the statisticsrequired by the test method. Differences between laboratoriescan be tested with standard statistical techniques such as thenull hypothesis.10.2 Bia
20、sThe procedure of this test method for theadhesion of mineral aggregate to hot bitumen has no biasbecause the quantity of aggregate adhered in the laboratory isdefined by this test method.11.
