SHRP-A-379 traducir

2.2 This practice is applicable to specimens prepared in a laboratory mix design
procedure or cored from a pavement for post-construction performance analysis.
2.3 Compiete analysis of the test results from the SUPERPAVE ® shear test device
requires the SUPERPAVE ®Specification, Mix Design and Support Program.

4. SUMMARY OF THE PRACTICE
4.1 SUPERPAVE ®Level 2 Mix Design
4.1.1 A sequence of three tests is performed with the shear test device in the level 2
mix design. At each asphalt binder content, four specimens are tested at two different test
temperatures. The level 2 test matrix is summarized in table 1.
4.2 SUPERPAVE ®Level 3 MIX Design
4.2.1 A sequence of five tests is performed with the shear test device in the level 3
mix design. At each asphalt binder content, six specimens are tested at four different test
temperatures. The level 3 test matrix is summarized in table 2.
and 2.
4.3 The following sequence of steps is common to each of the tests shown in tables 1
4.3.1 Prepare test specimens. Saw specimen ends perpendicular to the longitudinal
axis of the specimen; clean; measure dimensions; and determine specific gravity of each
specimen.
