(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 LTPPBind Online calculated maximum pavement design temperature and the minimum pavement design temperature.
Note 1: For more information on LTPPBind Online, see https://infopave.fhwa.dot.gov/Tools/LTPPBindOnline accessed July 10, 2023.
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.

Overview
ASTM D6626-23: Standard Specification for Performance-Graded Trinidad Lake Modified Asphalt Binder sets out the requirements for asphalt binders modified using Trinidad Lake asphalt. This performance-graded binder is widely used in road construction, adapted according to the specific pavement design temperature range. The standard helps ensure quality, consistency, and suitability of Trinidad Lake modified asphalt binders for diverse climates and roadway conditions. The document details grading, material composition, testing, and quality assurance to ensure binders meet demanding pavement performance needs.
Key Topics
- Performance Grading: Binders are classified by average seven-day maximum, intermediate, and minimum pavement design temperatures, determined via LTPPBind Online calculations.
- Material Composition: Trinidad Lake asphalt is added to petroleum-based base asphalt. The resulting binder must be homogeneous, free of water and harmful impurities, and must not foam at 175°C.
- Solubility and Viscosity: The binder should have at least 99% solubility in N-Propyl Bromide and meet specified viscosity limits, to ensure optimal mixability and durability.
- Testing Methods: Recognized ASTM test methods (such as D92, D95, D140, D1754, D2872, D4402, D6521, D6648, D7175, and D7553) verify properties like flash point, viscosity, rheology, aging, and physical hardening.
- Sampling and Inspection: Specifies how to sample asphalt materials and outlines procedures for inspection, rejection, and retesting to ensure compliance with the specification.
- Ordering and Designations: When ordering, users must specify the required performance grade (e.g., TLG 52-16 or TLG 64-34) aligned with the table of available grades.
Applications
- Road and Pavement Construction: Performance-graded Trinidad Lake modified asphalt binders are crucial for highways, urban roads, rural access roads, and airport runways. Their adaptability to temperature extremes makes them suitable for a wide range of climatic conditions.
- Climate-Specific Projects: The grading system allows engineers to select the right binder for regions with high-temperature fluctuations, improving pavement lifespan and reducing maintenance needs.
- Pavement Rehabilitation: Used in resurfacing and maintenance projects, these binders help restore and extend the performance of existing asphalt pavements.
- Quality Assurance: Consistency in material performance aids state and municipal agencies and contractors in meeting project specifications and regulatory requirements.
