Terminology3.1 DefinitionsFor definitions of terms used in this testmethod, see Terminology D 1079.4. Summary of Test Method4.1 Asmall section of roof surface is
6、 fabricated with roofingfelt or membrane using 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
7、of mineral aggregate adhered to thesurface of 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 metho
8、d provides a laboratory means of deter-mining 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-l
9、b) capacity, sensitive to 0.01 % of thecapacity.6.3 Containers, for hot bitumen and mineral aggregate (1-L(1-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 D 226.7.2 Attach the satu
10、rated felt to the inside of the tray with athin film of 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 aggreg
11、ate surfacing 61%.Record this mass as A. This is equivalent to 19.5 kg/m2(400lb/100 ft2) and 14.6 kg/m2(300 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 spr
12、ead uniformly over entire surface within the tray.Allowthe assembly 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

Calculation8.1 Calculate the mass of the adhered aggregate for each testas:C 5 A 2 B (1)where:C = mass of the adhered aggregate in pounds per squarefoot (4.88 (A B) gives the
16、 mass of the adheredaggregate in kg/m2).8.2 Calculate the mean mass of the adhered aggregate Cmbydividing the sum of the four determinations by four.8.3 Calculate an estimate of the standard deviation s by:s 54(C22 (C!212(2)8.4 Calculate the standard error of the mean S by:S 5s2(3)9. Report9.1 Repor
17、t the following information:9.1.1 The type of aggregate, including screen grading, andthe type of bitumen used.9.1.2 The mass of the adhered aggregate for any singledetermination as Cm6 3.18 3 s (95 % level of confidence).9.1.3 The mean mass of adhered aggregate as Cm63.18 3 S.10. Precision and Bias
18、10.1 PrecisionThe precision 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 th
19、enull hypothesis.10.2 BiasThe 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.
