While many technical manuals focus strictly on field application, MS-26 provides a deep dive into the "why" behind material behavior. It is the primary resource used by state DOTs, refinery chemists, and laboratory technicians to ensure pavement longevity. Key topics covered in the handbook include:
that focuses entirely on asphalt binders (bitumen). It serves as a consolidated resource, merging information from several other Asphalt Institute publications including MS-4, MS-5, and SP-1. Gilson Co. Best Ways to Access or Download Official Digital & Physical Purchase
As the industry shifted from empirical methods to the mechanistic-empirical design of pavement structures, the need for a comprehensive manual on binder chemistry, rheology, and testing became paramount. MS-26 fills that gap. Whether you are a materials engineer, a contractor, or a student, here is why this handbook is considered the "bible" of asphalt binders.
Many universities with civil engineering programs (e.g., Texas A&M, UC Berkeley, Purdue) have institutional subscriptions. If you are a student or faculty:
While many users search for a free "PDF download" of this handbook, it is important to note that MS-26 is a copyrighted technical manual.
