If your lab is using an from before 2015, you are likely missing:
A: Yes. It includes AASHTO T 48 (Cleveland Open Cup) and T 79 (Tag for cutbacks), though PG binders primarily use T 48.
If you are looking for the official, comprehensive text, it is highly recommended to acquire it directly from authorized sources:
While I don't have the specific content of MS-26, Asphalt Institute publications typically cover a range of topics, including:
As a step-by-step reference for executing standardized lab testing and troubleshooting irregular results.
The manual provides an exhaustive breakdown of the Superpave Performance Grading (PG) system, which classifies binders based on their performance under specific climate and traffic conditions (e.g., PG 64-22).
One of the highest-value sections of the MS-26 PDF is its detailed explanation of Superpave test methods. It clarifies not just how to run the tests, but why they matter:
The "MS-26" likely refers to a specific publication or standard from the Asphalt Institute. Without more context, it's a bit challenging to provide a direct link or the exact content you're seeking. However, I can guide you on how to find or access such documents:
This foundational section covers the origins of asphalt, from its natural sources to modern petroleum refining processes. It defines key terminology and introduces the chemical and physical constituents of asphalt binders, explaining how these properties dictate their behavior in paving applications.
The current edition of the aligns closely with AASHTO (American Association of State Highway and Transportation Officials) standards. Here is what you will find inside:
MS-26 incorporates AASHTO methods but adds Asphalt Institute-specific recommendations, especially for material properties and climate adjustment.
Assessing fluid properties for spray applications like chip seals.
The binder becomes brittle. Without proper testing, the road "cracks" as the earth shifts. The Turning Point: The Superpave Revolution
Best practices for production, storage, and sampling.
Liquid asphalt binders are typically handled at temperatures ranging from 250°F to over 350°F (120°C to 175°C). At these temperatures, contact causes severe, deep-tissue thermal burns. Furthermore, certain cutback asphalts release flammable vapors. MS-26 places a heavy emphasis on personal protective equipment (PPE) and safe handling practices. Mandatory PPE for Asphalt Sampling:
Digital PDF copies and printed versions can be purchased directly from the official Asphalt Institute online store. Purchasing guarantees you receive the most current edition, including any recent errata or technical updates.
