Asphalt is the backbone of modern infrastructure, paving millions of miles of highways, runways, and local roads worldwide. However, the performance and longevity of an asphalt pavement depend entirely on the quality of its components. To ensure that asphalt binders, emulsions, and mixtures meet strict engineering specifications, rigorous testing is mandatory.
MS-26 is a technical manual published by the Asphalt Institute that provides guidance on the selection, application, and performance of polymer-modified asphalt binders (PMAs). It summarizes best practices for using PMAs in paving and roofing applications, discusses laboratory testing and specifications, and explains how modifiers influence binder properties and pavement performance.
