Adapting to Industry Change: How HC+M Companies Stay Ahead

AMI plant in Indianapolis

In a constantly evolving industry, success isn’t just about reacting to change – it’s about working together to navigate transitions. HC+M companies understand that when industry-wide shifts occur, collaboration and expertise are essential in ensuring smooth implementation. The recent change in liquid asphalt binder specifications by the Indiana Department of Transportation (INDOT), from PG 64-22 to PG 58-28, exemplifies how companies must come together to maintain quality and efficiency while meeting evolving standards. 

HC+M companies prioritize a proactive approach to industry changes, ensuring customers receive high-quality products without disruption. This commitment aligns with the forward-thinking approach of Asphalt Materials, Inc. (AMI), which has played a key role in developing innovative solutions and automated systems to facilitate a smooth shift to PG 58-28. 

In partnership with the Heritage Research Group (HRG), AMI explored new strategies for creating asphalt blends by working with departments including supply, operations and sales to refine solutions. As part of this effort, the engineering department developed an improved storage plan and implemented an automated asphalt blender system to enhance efficiency and ensure reliable production of the updated specification blends. AMI efficiently integrated new testing methodologies, aligning with AASHTO M332 and R92 requirements to guarantee that all liquid asphalt binders meet industry requirements and optimize performance for Indiana’s climate extremes. 

Experts in chemistry and engineering play a critical role in refining formulations, continuously testing and improving materials so that they not only meet but exceed evolving demands. The dedication of our teams ensures that HC+M companies remain at the forefront of industry advancement, reinforcing our commitment to quality and reliability. 

Industry changes like INDOT’s updated liquid asphalt binder specifications reflect a broader movement toward longer-lasting, higher-performing pavements. At HC+M, our ability to pivot, innovate and collaborate positions us to meet these changes head-on. By fostering strong partnerships and maintaining a forward-thinking approach, we are not just adapting to change, we’re shaping the future of infrastructure with innovation, reliability and industry leadership.
