Standard Specification for Performance-Graded Trinidad Lake Modified Asphalt Binder
The following bibliographic material is provided to assist you with your purchasing decision:
This specification covers the standards for graded Trinidad Lake modified asphalt binders. Grading is related to the average seven-day maximum pavement design temperature, the intermediate pavement design temperature, and the minimum pavement design temperature. The Trinidad Lake modified asphalt binder shall be prepared by adding the Trinidad Lake asphalt modifier to base asphalt produced from the refining of petroleum crude. The base asphalt binder shall be homogenous, and free from water or any deleterious materials.
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.
