PHALANX Archives

Warm mix asphalt is paving mix that can be produced and compacted at lower temperatures than traditional hot mix asphalt materials for roadway development. This may result in reduced greenhouse gas (GHG) and asphalt emissions through lower operational temperature requirements at the plant and at the job site. PHALANX®, a specially engineered warm mix additive, is designed to improve compactability of hot asphalt mixes and Polymer Modified Bitumen (PMB) mixes. It helps reduce the paving temperature when laying down a roadway. PHALANX helps lower the carbon footprint, reduce energy consumption, and deliver overall cost savings.

Warm Mix Asphalt: Pros and Cons of WMA Technology in Paving

Warm mix asphalt (WMA) primarily differs from its hot mix asphalt (HMA) counterpart on the basis of providing for lower asphalt production and compaction temperatures, which can be between 30 to 120°F less than HMA applications. However, WMA offers a number of key advantages over traditional HMAs beyond temperature reduction. While WMAs are no longer uncommon across the paving [...]

Warm Mix Asphalt Temperature Ranges and Benefits for Roadway Paving

With concerns around sustainability in asphalt increasing across the paving industry, more mix engineers are turning to warm mix asphalt (WMA) to design paving mixes that help reduce emissions while continuing to meet performance specifications. Currently, over 40% of asphalt pavement construction in the United States uses warm mix asphalt technology. Additionally, agencies such as Highways England are exploring [...]

Is Sustainable Asphalt a Reality?

Developing infrastructure remains a key focus for global departments of transportation, with conservative estimates placing new road construction projects at a value of $3.4 trillion. The global market for asphalt production is expected to reach 138 million tons by 2027. Simultaneously, 107 countries have also made pledges to pursue net-zero emissions according to the United Nations. At the [...]
