(Specification)Standard Specification for Performance-Graded Trinidad Lake Modified Asphalt Binder
Standard Specification for Performance-Graded Trinidad Lake Modified Asphalt Binder
ABSTRACT
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 performance-graded Trinidad Lake modified asphalt binders. Grading designations are related to the average seven-day maximum pavement design temperature, °C, the intermediate pavement design temperature, °C, and minimum pavement design temperature, °C.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
