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.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. 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.

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