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 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 [...]

PHALANX Warm Mix Additive Development Featured in Roads & Infrastructure Australia

Warm mix additive development has traditionally been focused on lowering mix compaction temperatures. The team at Sripath has continued to innovate the warm mix additive space with the recent launch of PHALANX®. PHALANX is a superior warm mix additive (WMA) that helps lower both production and compaction temperatures without sacrificing performance requirements. The story was recently covered in [...]

Warm Mix Additives for Asphalt – Frequently Asked Questions

Warm mix additives for asphalt (WMAs) may be newer to the paving industry, but they are becoming increasingly important as contractors look to achieve density and smoothness of roadway surfaces while also meeting sustainability standards. These additives can help agencies achieve reduced emissions onsite and aid material compaction for potentially higher performing roads. Key to the process is [...]
