17、ge.8. Test Methods8.1 Significance and Use:8.1.1 The distortion and brittleness tests are used to deter-mine the handling characteristic of the material. The waterabsorption and compression tests are used to determine thesuitability of the material as an expansion joint filler.8.2 Procedures:8.2.1 D

18、istortion at 52C (125F)Cut a test specimen 51by 152 mm (2 by 6 in.), substantially flat and straight, with the152-mm dimension parallel to the machine direction of thestrip. Clamp the specimen between two blocks so that theexpansion joint forms a cantilever of 89-mm (312-in.) length.Place the clamp

19、and joint assembly in a forced-draft ovenmaintained at 52 6 1.1C (125 6 2F), with the specimen ina horizontal position, for 2 h. Measure the deflection of thespecimen from the horizontal.8.2.2 BrittlenessCut a test specimen 51 by 152 mm (2 by6 in.) with the 152-mm dimension parallel to the machinedi

20、rection of the strip. Maintain the specimen at a temperatureof 4 to 6C (39 to 43F) in water for at least 2 h prior to testing.Clamp the specimen between two boards so that the expansionjoint forms a cantilever of 89-mm (312-in.) length and hold ina horizontal position by a suitable rigid support. Su

21、spend aspherical cast iron ball, weighing 0.43 kg (0.95 lb) and havinga diameter of 48 mm (178 in.), by a cord tied to an eyeletfastened to the ball. For specimens having a thickness of 14.3mm (916 in.) or less, suspend the ball 304 mm (1 ft) above thecenter of the projecting portion of the specimen

22、. For specimensover 14.3 mm in thickness, suspend the ball 610 mm (2 ft)above the specimen. Release the ball by burning the cord abovethe eyelet. Other suitable suspension and release devices maybe used.8.2.3 Water AbsorptionCut a test specimen 51 by 152 mm(2 by 6 in.) from the joint filler material

23、, in such a manner thatall edges are freshly cut, and weigh. Immerse the specimenhorizontally under 25.4 mm (1 in.) of distilled or deionizedwater at 23 6 2C (73.4 6 3.6F) for 24 h, remove, and wipeoff the surface water with a slightly dampened cloth. Weigh thespecimen quickly and calculate the gain

24、 in weight and expressas weight percent of water absorbed.8.2.4 CompressionTest the joint filler in accordance withthe compression test outlined in Methods D 545, except makeonly a single application of the load required to compress thespecimen to 50 % of its thickness before test, and do notmeasure

SINGLE-OPERATOR PR

28、ECISION STATEMENTSX2.1 Practice C 670, for Preparing Precision and BiasStatements for test methods for Construction Materials, wasused to develop the single-operator precision statement.X2.2 Windows 95 function categories were used to calcu-late the average (avg) values and the one-sigma (1s) limits

29、.Data was graphed using Windows 95 Chart Wizard.X2.3 Acceptance of individual measurement values wasbased on the calculated difference of two-sigma (d2s) limits asthe appropriate index of test precision. Maximum acceptancerange of the measurements was calculated per Practice C 670,and for a given te

30、st the individual results of the measurementswere accepted if the results were within the calculated maxi-mum acceptable range.X2.4 Single-Operator Precision was calculated per PracticeC 670. Results of three (3) specimens were used to calculatethe average values and the one-sigma limits. From Pract

31、iceC 670, for the average of three (3) measurements, the multi-plier is 5.7 for the maximum acceptable range of individualmeasurements. The precision statement then for a single-operator is calculated as follows:Precision Statement 51s!35.7 (X2.1)X2.5 Calculated precision statements for the various
