Comment from Brandon Brever, Minnesota Asphalt Pavement Association, bbrever@mnapa.org, 10/31/2024
Life Cycle Value of HMA:
New HMA pavement (Alternate #3) can offer better long-term performance and durability than rehabilitation options, as it provides a new pavement structure. This can result in fewer required interventions and lower maintenance costs over time, especially beneficial on a heavily trafficked route.
HMA can reduce the frequency of maintenance activities compared to shorter-cycle alternatives, minimizing traffic disruptions and long-term costs.
Long-Term Performance and Reduced User Costs:
Asphalt pavements are known for their smoothness and ability to reduce wear and tear on vehicles, lowering user costs.
A new HMA (Alternate #3) provides an excellent balance of cost, durability, and user benefits, making it an ideal choice for projects where user experience and reduced maintenance costs are priorities.
Environmental Benefits:
HMA pavements are compatible with high recycled content (100% of asphalt pavements are recycled), contributing to sustainability goals. Utilizing RAP (Recycled Asphalt Pavement) aligns with environmental objectives by reducing the demand for virgin materials and lowering carbon emissions associated with production.
Flexible Maintenance Options:
Asphalt pavements provide a range of flexible maintenance options that can be implemented quickly, such as overlays and surface treatments, ensuring that road performance remains optimal over time.
This flexibility allows for quick and cost-effective repairs, which is particularly advantageous for high-use roads where minimizing downtime is essential.
Resilience and Adaptability:
With climate resilience becoming a significant consideration, asphalt’s adaptability to various weather conditions and potential for innovative additives (e.g., warm-mix asphalt technology) make it a forward-looking choice.
The choice of HMA could align well with future requirements to adjust to evolving climate conditions or state and federal funding priorities that prioritize resilient infrastructure.
Considering these comments, New HMA (Alternate #3) is a cost-effective, sustainable, and resilient pavement option, supporting both immediate and long-term project goals.
