PMB mixes have been popular for decades and are designed to maintain the integrity of the roadway while enhancing functional performance characteristics. Most virgin bitumen lacks the complete properties needed in quality to build high-performing roadways. Adding polymers to create a PMB can help strengthen and toughen the roadway surface. PGXpand®, a bitumen-friendly polymer additive, is uniquely designed to allow polymer modified bitumen (PMB) producers to boost the high temperature performance of the binder while maintaining low temperature properties. It minimizes SBS content, improves viscosity, supports higher filler loading, and provides better stability.

Understanding Polymer Modified Bitumen (PMBs) – Frequently Asked Questions

Paved roadways have been around since ancient Babylonian civilizations began blending asphalt with gravel to accommodate travelers and merchants. In more modern times, roads constructed from asphalt, or bitumen, appeared in the late 1700s as chemists started to better understand the binding qualities of natural asphalt in surface performance. Fast forward to today, and the Earth is [...]

Sustainability in Asphalt with Sripath Additives That Support a Reduced Carbon Footprint

Traditional methods and materials for roadway development may be here to stay, but the advent of sustainably produced additives that may support contractor and department of transportation goals to lower their carbon emissions are much newer to the industry. Newer still is the perspective that asphalt and bitumen additives can be produced with a lower carbon footprint, helping [...]
