Workmanship, Finish, and Appearance7.1 The asphalt plank shall be free from defects affecting itsserviceability and appearance; it shall have straight edges andsquare corners.8. Sampling8.1 For the purpose of testing, three planks shall be selectedat rand

16、om by the purchaser or his representative for each 1000planks or fraction thereof for each thickness included in theshipment.9. Test Methods9.1 ScopeThe four test methods listed in this section areintended to measure those attributes necessary to measure theability of asphalt plank to provide a reas

17、onably long andsatisfactory service. They are listed as follows:Test Method SectionAbsorption 9.2Brittleness 9.3Dimensions 9.4Hardness 9.59.2 Absorption:9.2.1 ScopeThis test method covers the determination ofwater absorption of asphalt plank.9.2.2 Significance and UseThe ability of the plank towiths

18、tand significant water absorption is a measure of itsporosity and therefore its ability to withstand freezing andthawing conditions. It is a measure of its density.9.2.3 ProcedureA specimen 50.8 by 152.4 mm (2 by 6in.) shall be cut from the asphalt plank in such a manner that alledges are freshly cu

19、t. The mass of the specimen shall beaccurately determined to the nearest 0.10 g, immersed in waterfor 24 h, removed, and the surface water wiped off with aslightly dampened cloth. The mass of the specimen shall thenbe determined to the nearest 0.10 g and the percent absorptiondetermined. The time el

20、apsing between the removal of thespecimen from the bath and its weighing shall not exceed 1min.9.3 Brittleness:9.3.1 ScopeThis test method covers the determination ofbrittleness of asphalt plank.9.3.2 Significance and UseThis test measures the abilityof the plank to function in cold temperatures wit

21、hout detrimen-tal cracking.9.3.3 ProcedureTwo 152.4 by 152.4 mm (6 by 6 in.)specimens shall be cut from each of the three sample planksselected in accordance with Section 8. Five of those specimensshall be tested as follows: The specimens shall be conditionedand maintained at a temperature of 0C (32

22、F) for not less than3 h, and then tested immediately. A 0.9-kg (2-lb) weightdropped from a height of 508 mm (20 in.) onto a 5.7 mm(0.225 in.) diameter cylindrical pin shall not cause a crack toextend more than 37.5 mm (1.5 in.) from the point of impact.The point of impact shall be as close to the ce

23、nter of the sampleas possible.9.4 Dimensions:9.4.1 ScopeThis test method covers the measurement ofdimensions to determine if the sample complies with the planor specification requirements.9.4.2 Significance and UseThis test method will ensurethat the finished product in place will afford an even, un

24、iformbearing surface for subsequent construction.9.4.3 ProcedurePlank from each lot shall be examined forappearance, straightness of edges, and squareness of corners,and measured for width and length to an accuracy required inSection 6. They shall also be calipered at four scattered pointseach, with

25、 a micrometer having flat bearing surfaces at bothcontact points of not less than 6.4 mm (14 in.) in diameter. Theaverage of the readings shall be considered the thickness of theplank.9.5 Hardness:9.5.1 ScopeThis test method covers the determination ofhardness of asphalt plank.9.5.2 Significance and

26、 UseThis test method measures theability of the asphalt plank to withstand serviceable loads andto ensure that the grade of asphalt used is proper to serve underwarm temperature without excessive deformation.9.5.3 ProcedureThe hardness of the plank shall be deter-mined by means of a McBurney penetro

27、meter in which the pinin contact with the plank during the test is a hemispherical pin5.7 mm (0.225 in.) in diameter. The specimen shall be keptsubmerged in water maintained at the temperature specified fora time sufficient to ensure that the specimen has attained thistemperature throughout. The tes

28、t shall be made with thespecimen supported on a smooth, solid support. The tests shallbe performed upon samples at least 152.4 mm (6 in.) in lengthand of the full width of the plank. In each case the requiredload shall be applied for a period of 60 s, and the contact pinof the penetrometer shall be

29、applied to the specimen at points37.5 mm (1.5 in.) or more from the edge of the specimen.9.6 Precision and Bias:9.6.1 PrecisionAttempts are being made to determine theprecision of the two tests in this standard that result in anumerical value.9.6.2 BiasNo statement can be made on the bias of thetest
