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.
1.1 This specification covers performance-graded Trinidad Lake modified asphalt binders. Grading designations are related to the LTPPBind Online calculated maximum pavement design temperature and the minimum pavement design temperature.
