8 Step Framework for Balanced Mix Design in Asphalt

TRANSCRIPT: Asphalt mix design engineers are facing challenges in balancing requirements for roadway durability, sustainability, and cost. Using balanced mix design, or BMD, shifts the focus from volumetric properties to performance testing. This can help engineers optimize resistance to rutting, cracking, aging, and fatigue while also potentially reducing costs and leveraging eco-friendly solutions such as reclaimed asphalt [...]

Examples of Sustainability in Asphalt Paving

Sustainability has become a central topic of focus across all sectors of the asphalt paving industry. Local governments and departments of transportation are considering how updated specifications can lead toward meeting broader net zero emissions goals. Producers and contractors are looking for different technologies that can help meet performance requirements while lowering their own carbon footprint and keeping [...]

How to Choose an Ideal Asphalt Rejuvenator

Using reclaimed asphalt pavement (RAP) offers several key benefits to producers and mix designers looking to trim costs from their mixes while delivering performance/specification requirements. Importantly, increasing the amount of RAP in a mix can reduce the need for virgin bitumen and aggregates. Using RAP also helps to reduce waste and, and durable, RAP-based roadway surfaces can support [...]

VIDEO: Why Bitumen Quality Matters in Asphalt Roadway Production

TRANSCRIPT: As global demand for roads grows, so does the importance of the material that holds them together: bitumen. However, once a consistent, locally sourced byproduct of oil refining, bitumen quality has become increasingly unpredictable. Why? Because modern refineries now prioritize extracting other outputs, resulting in bitumen of varying, often lower quality. Bitumen [...]
