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, ^o C, the intermediate pavement design temperature, ^o C, and minimum pavement design temperature, C.

Note 1--For asphalt cements graded by penetration at 25 ^o C, see Specification D946. For asphalt cements graded by viscosity at 60 ^o C, 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.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
