ustainability and transparency have become key drivers of innovation in today's asphalt paving industry. The value chain of material suppliers, producers, and municipalities is experiencing increased pressure to quantify environmental impacts and make data-driven decisions. One of the most effective tools enabling this shift is the Environmental Product Declaration (EPD). 

 

What Is an Environmental Product Declaration (EPD)? 

An EPD is a standardized document that communicates the environmental impact of a product throughout its life cycle. Developed according to international standards such as ISO 14025 and EN 15804, an EPD can provide transparent data on metrics like global warming potential (carbon footprint), resource use and depletion , energy consumption, and emissions in addition to a host of other environmental impacts. 

 

In the asphalt industry, EPDs are particularly valuable because they quantify the environmental footprint of materials such as bitumen, asphalt binders, polymers, rejuvenators, modifiers, and additives. This enables key decision makers to compare options based on objective, third-party verified data rather than marketing claims. 

 

Why EPDs Matter in Asphalt Paving Projects 

For decades, sustainability conversations in infrastructure were limited to cost, performance, and durability. Today, measurable factors like carbon intensity and environmental impact have become just as important. Departments of transportation and asphalt producers are increasingly requesting EPDs as part of their procurement or bid specifications. 

 

By analyzing EPD data, decision makers can: 

  • Quantify the carbon footprint of their paving materials 
  • Evaluate the environmental performance of different products or formulations 
  • Select asphalt additives aligned with sustainability targets such as greenhouse gas (GHG) emissions 

 

In short, EPDs empower organizations to make informed, science-based decisions. This has become a critical step toward reducing the overall environmental impact of asphalt road construction. 

 

The Need for Transparency Around Asphalt Industry GHG Emissions 

Despite their importance, EPDs have not always been widely shared within the asphalt and construction materials sectors. Some companies have traditionally regarded EPDs as internal documents available only on request. Other firms hesitate to publish these documents due to competitive concerns or misunderstandings about what the data represents. 

 

This lack of transparency has limited the broader industry's ability to benchmark and improve its sustainability efforts. Without open access to environmental data, engineers can encounter barriers to making truly informed decisions. Moreover, the absence of shared data can slow collective progress toward sustainability goals. 

 

Leveraging Environmental Product Declarations for More Sustainable Asphalt Solutions 

EPDs are more than just compliance documents. They are strategic tools for product selection, process optimization, and long-term sustainability planning.  

  • Producers can use EPD data to identify environmental improvement opportunities in manufacturing, sourcing, or mix formulations. 
  • Municipalities and departments of transportation can include EPD requirements in procurement to ensure taxpayer-funded projects contribute to established climate goals. 
  • Contractors and consultants can use EPDs to demonstrate environmental leadership and differentiate their services. 

 

As the industry moves toward specifications that value both performance and sustainability, accessible and accurate EPD data can be a critical differentiator. 

 

Sripath Sets a New Standard for Openness 

Recognizing the importance of transparency, Sripath Technologies has taken a groundbreaking step by making its individual product EPDs publicly available on its corporate website. This decision, led by Sripath's executive team, underscores the company's belief that openness fosters innovation, accountability, and collaboration across the asphalt industry. 

 

By publishing EPDs for products such as ReLIXER®, PGXpand®, PHALANX®, NuMIXER®, and ReNUBIT®, Sripath provides direct access to verified environmental data. Third-party analysis and EPD development is also underway for Sripath's latest product release, ButaPhalt®, and will be published once complete. 

 

Making EPDs available allows industry stakeholders to: 

  • Understand each product's environmental impact profile in detail 
  • Incorporate sustainability metrics into material selection and mix design 
  • Confidently specify products that support low-carbon and circular economy goals 

 

Sripath's transparent approach sets a precedent for the asphalt industry and demonstrates how sharing environmental data is a responsibility. 

 

Building a Circular Future for Asphalt Paving 

At its core, the push for EPD disclosure aligns with the asphalt industry's commitment to the circular economy. This effort includes using recycled materials, reducing waste, and lowering energy consumption all while extending pavement life.  

 

Products like ReLIXER exemplify how data-driven sustainability and innovation can be achieved together. ReLIXER exhibits a negative global warming potential (GWP) as documented in the product's EPD, which covers a cradle to gate lifecycle analysis. A bio-based asphalt rejuvenator engineered to restore aged bitumen in reclaimed asphalt pavement (RAP), ReLIXER enables the production of high-RAP mixes that compact easily and deliver long-lasting performance comparable to virgin mixes. By allowing contractors to recycle existing road materials, ReLIXER helps reduce greenhouse gas emissions, lower the need for virgin bitumen and aggregates, and shrink the overall carbon footprint of paving projects.  

 

Its EPD also accounts for carbon sequestration during biogenesis. The renewable oils used in ReLIXER are derived from plants that capture and store CO₂ during growth. As such, the carbon remains locked within the pavement throughout its service life and reuse cycles, contributing to a more sustainable, circular asphalt economy. 

 

A Transparent Path Forward for Sustainable Asphalt Paving 

Public EPD disclosure is one way for the asphalt industry to address demands for accountability and climate-conscious performance. Sripath's leadership team has highlighted how sharing verified environmental data can drive collaboration and help municipalities and producers achieve greener roads.
