Polymer Modified Binders, Hybrid Modification

The separation of polymer and asphalt during hot storage is evaluated by comparing the ring and ball softening point of the top and bottom portions taken from a conditioned, sealed tube of polymer-modified asphalt. The conditioning consists of placing a sealed tube of polymer modified asphalt in a vertical position in a 163+ 5°C (325 + 10°F)

polymer modified bitumen modified bitumen modified asphalt

When a polymer is added to regular bitumen, it becomes more elastomeric, which provides it with additional elasticity. The polymer that is added is styrene butadiene styrene (SBS), which acts as a binder modification agent. The primary objective of SBS polymer modified bitumen is to provide extra life to pavement, roads and construction designs.

Introduction to Rubberized Asphalt Index

Defines asphalt rubber binders as “a blend of paving grade asphalt cements, ground recycled tire (that is, vulcanized) rubber and other additives, as needed, for use as binder in pavement construction. The rubber shall be blended and interacted in the hot asphalt cement sufficiently to cause swelling of the rubber particles prior to use.”

Asphalt Modifiers – Pavement Interactive

Asphalt Modifiers. Some asphalt cements require modification in order to meet specifications. Asphalt cement modification has been practiced for over 50 years but has received added attention in the past decade or so. The added attention can be attributed to the following factors (Roberts et al., 1996 [1] ): Increased demand on HMA pavements.
