No. The PDF is a manual. However, the Asphalt Institute sells companion software (WINPAS, Asphalt Pavement Designer) separately.

Asphalt is a complex hydrocarbon material derived from the distillation of selected crude oils. MS-26 breaks down the molecular structure of asphalt, detailing its main chemical fractions:

~1,450 words (optimized for SEO, readability, and depth).

Praised for being "appropriate but not overly technical," making it readable from cover to cover or useful as a quick reference guide. Comprehensive

For professionals in the field, having a digital copy of the MS-26 manual (PDF) allows for immediate access to critical charts, graphs, and testing methodologies during project design or troubleshooting.

By mastering the principles in MS-26, engineers can design mixes tailored to combat specific distresses:

The manual breaks down the complex molecular matrix of asphalt into two primary fractions:

This section addresses materials beyond conventional asphalt cement. It covers:

The , titled The Asphalt Binder Handbook

The publication emphasizes the importance of proper pavement design, which involves considering several factors, including:

The 9th Edition provides both US customary and SI units. Older editions are primarily imperial.

This is the core of the handbook, delving into the standardized tests used to characterize and specify asphalt binders. It explains the evolution from historical grading systems (like viscosity and penetration grading) to the current state-of the-practice: the . This system, developed under the Strategic Highway Research Program (SHRP), grades binders based on their performance at specific high and low pavement temperatures, which is critical for building durable roads.
