Phạm vi áp dụng / Scope of standard

This specification covers asphalt binders graded by performance.
Grading designations are related to the average 7-day maximum
pavement design and minimum pavement design temperatures. This
specification incorporates new procedures for determining the
critical low cracking temperature using a combination of the T 313
and T 314 test procedures. This testing regimen is a rigorous
approach that is inclusive of most modified materials.

Note 1-For asphalt binders graded by
penetration at 25"C, see M 20. For asphalt binders graded by
viscosity at 6OoC, see M 226.

Note 2-R 29 provides
information for determining the performance grade of an asphalt
binder.
