Urbanization, Roadway Development, and Asphalt Paving

Across the globe, cities are expanding at unprecedented rates, driven by population increases, economic opportunity, and the desire for connected, accessible lifestyles. In fact, by 2050, nearly 70% of the world’s population is expected to live in urban areas. To support all of this growth, demand for expanded and upgraded transportation infrastructure is leading conversations across the [...]

Crosslinkers for Polymer Modified Bitumen – Frequently Asked Questions

Crosslinkers are a key component for enhancing the performance of Polymer Modified Bitumen (PMB). These additives can help enhance the bond between polymers and bitumen in a mix and improve durability, elasticity, and rutting resistance. Notably, crosslinking agents can differ in terms of chemistry, reactivity, and dosage requirements. Because of this, asphalt crosslinkers must be carefully selected and introduced at [...]

High-RAP Mixes at Scale with an Asphalt Rejuvenator

Asphalt is the most recycled material in the United States according to the National Asphalt Pavement Association (NAPA), amounting to nearly 97 million tons of reclaimed asphalt pavement (RAP). As a result, over 90% of new roadway surfaces in the U.S. are built using RAP. This trend is spreading globally as more contractors and transportation agencies explore the [...]

Reducing Variability in RAP Mixes During Plant Production

Asphalt producers are increasingly relying on reclaimed asphalt pavement (RAP) to meet environmental goals and cost-efficiency targets. Using RAP can allow aggregate and aged binder to be reused, reducing the need for virgin materials and lowering overall material costs. However, one key challenge that working with RAP poses to plant operators and mix engineers is variability. When [...]
