ASTM D7379/D7379M-08(2015)e1

Standard Test Methods for Strength of Modified Bitumen Sheet Material Laps Using Cold Process Adhesive

SIGNIFICANCE AND USE
3.1 These tests are useful in sampling and testing combinations of modified bitumen sheet materials used with cold applied adhesives.
SCOPE
1.1 These test methods cover the procedure for sampling and testing the strength of laps formed with adhesive used with polymer-modified bituminous sheet materials.  
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be sued independently of the other. Combining values from the two systems may result in non-conformance with the standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

D7379/D7379M − 08 (2015)
6.1.1 Modified Bitumen Samples for Testing—Samples for testing shall consist of two 140 by 152 mm (5.5[5.5 by 6 in.)in.] test
panels of modified bitumen, bonded with the adhesive to be tested, and cut into 25 mm (1 in.)[1 in.] specimens as shown in Fig.
1. Cut the modified bitumen sheet materials and mate the sides to be bonded facing each other.
6.1.2 Sides to be bonded shall be prepared in the same fashion as a field seam is constructed with the bottom side of a top panel
bonded to the top side (selvage) of the bottom panel using the adhesive to be tested.
6.2 Stir the adhesive to be tested until it is uniform. Spread 5.0 6 0.3 g of the adhesive evenly over the selvage portion of a
bottom panel. Place the top panel over the adhesive-coated area of the bottom panel (as shown in Fig. 1) in the same manner, as
a field lap would be made.
6.3 Roll the freshly prepared panel combination three times with a back-and-forth motion, taking care not to move the panels
during the rolling process. No downward pressure shall be exerted on the roller by the operator. The roller shall be placed in direct
contact with the 3-in. wide cemented lap portion. The roller shall be 127 mm (5 in.)[5 in.] 6 5 % wide, 127 mm (5 in.)[5 in.] 65 %
in diameter, and shall weigh 11.8 kg (26 lb)[26 lb] 65 %.
6.4 Conditioning—Heat condition completed modified bitumen panels prior to peel testing in a ventilated, forced air convection
oven at 70 6 3°C (158[158 6 5°F)5°F] for 7 days 6 2 h. Panels are to be placed in the oven within 24 h of preparation.
6.4.1 After conditioning, allow panels to come to constant temperature at 23 6 2°C (73.4[73.4 6 3.6°F)3.6°F] and 50 6 5%
humidity for 24 6 1 h prior to testing.
6.5 Specimens—Prepare five die cut test specimens from each panel. Discard the outer 5 mm (0.13 in.)[0.13 in.] of each panel
to avoid any edge effects. Specimens shall be 25.4 6 0.2 mm (1[1 6 0.01 in.)in.] by 152 6 2 mm (6[6 6 0.05 in.)in.] long.
Specimens for testing shall incorporate a 25.4 6 0.2 mm (1[1 6 0.01 in.)in.] by 76 6 0.6 mm (3.0[3.0 6 0.03 in.)in.] bonded area,
as shown in Fig. 1.
