ASTM D545-2019 pdf free download.Standard Test Methods for Preformed Expansion Joint Fillers for Concrete Construction (Nonextruding and Resilient Types)
3. Significance and Use
3.1 The compression resistance perpendicular to the faces, the resistance to the extrusion during compression, and the ability to recover after release of the load are indicative of a joint filler’s ability to continuously fill a concrete expansion joint and thereby prevent damage that might otherwise occur during thermal expansion. The asphalt content is a measure of the fiber-type joint filler’s durability and life expectancy. In the case of cork-type fillers, the resistance to water absorption and resistance to boiling hydrochloric acid are relative measures of durability and life expectancy. N OTE 2—The quality of the results produced by this standard are dependent on the competence of the personnel performing the procedure and the capability, calibration, and maintenance of the equipment used. Agencies that meet the criteria of Specification D3666 are generally considered capable of competent and objective testing, sampling, inspection, etc. Users of this standard are cautioned that compliance with Specification D3666 alone does not completely ensure reliable results. Reliable results depend on many factors; following the suggestions of Specification D3666 or some similar acceptable guideline provides a means of evaluating and controlling some of those factors.
4. Apparatus
4.1 Balance, for weighing joint fillers capable of weighing test specimens within 0.01 g.4.2 Mechanical Convection Oven, capable of maintaining 220 6 5.0 °F (104 6 3 °C). 4.3 Desiccator, of sufficient size to accommodate the test specimens. 4.4 Vernier Caliper, for measuring length and width of specimens with accuracy within 60.01 in. (0.25 mm). 4.5 Dial Micrometer, or other measuring device, graduated to read in 0.001-in. (0.02-mm) units. 4.6 Extrusion Mold—Three-sided steel mold to confine lateral movement of specimens under compression to one side only. Interior dimensions shall be 4 by 4 in. (102 by 102 mm) with permissible variations in length and width of 60.015 in. (0.38 mm). Mold sides shall be of such height as to extend at least 0.5 in. (13 mm) above the test specimens. A typical mold can be made from a steel base 1 ⁄ 2 by 4 by 4 6 0.015 in. (13 by 102 by 102 6 0.3 mm) and three bolted steel side plates 1 ⁄ 4 in. (6.35 mm) thick, extending approximately 1 1 ⁄ 2 in. (38 mm) above the base plate, thus forming a three-sided, open-top box. 4.7 Template—One steel template 4 by 4 in. (102 by 102 mm), machined from 1 ⁄ 2 -in. (12.7-mm) steel plate to fit the extrusion mold. The template shall fit the mold within −0.005 in. (0.13 mm) in length and width. 4.8 Metal Plate, 4 1 ⁄ 2 by 4 1 ⁄ 2 in. 6 0.1 in. (114 by 114 6 2.5 mm) with parallel faces machined from 1 ⁄ 2 -in. (12.7-mm) steel plate.4.9 Compression Tester, either hydraulic- or screw-type equipment with sufficient opening between upper- and lower- bearing surfaces to permit the use of verifying apparatus. The load applied to the test specimen shall be indicated with an accuracy of 61.0 %. The upper-bearing device shall be a spherically seated, hardened metal block firmly attached at the center of the upper head of the machine. The center of the sphere shall lie at the center of the surface of the block in contact with the specimen. The block shall be closely held in its spherical seat, but free to tilt in any direction. Load shall be applied without shock at 0.05 in. (1.3 mm) per min. 4.10 Extractor Apparatus, Soxhlet Extractor with thermo- statically controlled heating element.
5. Sampling
5.1 One representative sample approximately 2 ft 2 /1000 ft 2 of joint filler shall be obtained and properly packaged for safe transporting to the testing agency. 5.2 For self-expanding cork joint filler, a minimum of five 4 1 ⁄ 2 by 4 1 ⁄ 2 -in. (114 by 114-mm) square specimens properly banded and plastic wrapped at point of manufacture shall be submitted for testing.
