ASTM D6626-01 - 10.4.2001
 
1. Scope

1.1 This specification covers graded Trinidad Lake modified asphalt binders. Grading designations are related to the average seven-day maximum pavement design temperature, oC, the intermediate pavement design temperature, oC, and minimum pavement design temperature, C.

Note 1--For asphalt cements graded by penetration at 25 oC, see Specification D946. For asphalt cements graded by viscosity at 60 oC, see Specification D3381.

Note 2--AASHTO Guide PP5 provides information on the evaluation of modified asphalt binders.

1.2 The values stated in SI units are to be regarded as standard.
