Sustainability & Environment

Pavement design isn’t just about strength, smoothness, and cost anymore. It’s also about sustainability-how each material and process affects the environment across its entire lifespan. That’s where Life-Cycle Assessment (LCA) comes in. This analytical approach measures the total e…

Regulatory Pathways and Best Practices Why Wetlands and Sensitive Habitat Matter Wetlands slow floodwaters, filter pollutants, recharge aquifers, and anchor food webs. Fragmenting or burying them for a wider roadway can raise project costs, introduce permitting delays, and expose the agency (or its …

Why Air-Quality Matters in Asphalt Production Modern asphalt plants are far cleaner than their predecessors, but they still generate particulate matter (PM), volatile organic compounds (VOCs), sulfur oxides (SOₓ), nitrogen oxides (NOₓ), carbon monoxide (CO), and nuisance odors. Controlling these pol…

Why End-of-Life Strategy Matters When an asphalt or concrete pavement reaches the end of its service life, owners face a pivotal choice: remove and replace the structure in its entirety or harvest maximum value from the existing layers. The latter approach, designing an end-of-life (EOL) strategy, c…
