Trinidad Lake Modified Asphalt is a modified asphalt binder used to bind aggregates together to form the asphalt pavement.

Manufacturing Process:

Produced by the proportionate blending of 180/200 refinery bitumen, a heavy oil residue resulting from the refining of crude petroleum, with the world’s #1 modifier of refinery Bitumen, naturally occurring Trinidad Lake Asphalt (TLA).
Other Names: AC, TLAC, Trinidad Modified Asphalt (TMA), Trinidad Lake Asphalt Cement, Modified Asphalt, 60/75 Pen, Asphalt Cement

Composition:

Homogenous blend of 27-37% Trinidad Lake Asphalt and 63-73% Refinery Bitumen

Physical and Chemical Properties

Appearance: A semi-solid, brown to black material
Uses:

• Airport runways
• Roads
• Highways
• Bridge decks

Advantages of using Trinidad Lake Modified Asphalt
60/75 Asphalt Cement

• TLA components improve the ductility of the asphalt cement allowing the pavement to recover from distortions due to stress, without rupturing and rutting.
• The unique mineral matter component of the TLA adds non-skid properties to the pavement
• Increased stability and resistance to permanent deformation and rutting
• Decreased aging
• Resistance to cracking
• Increased fatigue performance
• Improved pavement load carrying
• Provides structural and durability improvements which lead to extended pavement life
• Withstands a wide temperature range
