This aspect has enabled a significant reduction in building expenses and environmental emissions.

Advancements in Asphalt Technology

Another breakthrough is absorbent asphalt, which allows water penetration the pavement, reducing runoff and improving water quality. These upgrades have increased the appeal of asphalt as an eco-conscious choice in road projects.

Challenges for Asphalt Paving
