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 [...]
