This is largely attributed to rapid growth in global infrastructure as demand for both new and refurbished roads takes the spotlight. Yet there are concerns that increasing road projects will impede environmental conservation efforts aimed at net zero carbon emissions. One way the industry [...]
TRANSCRIPT FROM VIDEO: While high-RAP mixes include any mix with more than 25% Reclaimed Asphalt Pavement, some departments of transportation are looking to push the envelope on RAP usage. When using an effective rejuvenator, RAP usage of up to 100% is possible while maintaining performance specifications. A field trial demonstrated the viability of 100% RAP mixes with [...]
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 [...]
TRANSCRIPT FROM VIDEO: The Illinois Tollway used Sripath’s asphalt rejuvenator, ReLIXER, to test the performance of a high-traffic roadway prone to extreme weather conditions. The goal was to incorporate a minimum of 40% Reclaimed Asphalt Pavement in their balanced mix design while achieving key performance specifications. When evaluating sample performance, Illinois Tollway used several different tests. The [...]
