Premier Graphene has initiated third-party testing on HGI Industrial Technologies’ proprietary graphene-enhanced asphalt. 

The collaboration between the two companies involves Premier Graphene integrating HGI’s graphene formulation into asphalt mixtures for testing.

The tests aim to assess the material’s performance in various global climates, focusing on structural strength and thermal conductivity when compared to standard asphalt formulations.  

Premier Graphene president Pedro Mendez said: “Our early, initial tests have yielded outstanding results. Our team believes that HGI’s unique graphene formulation, particularly given the results to date, is destined to dramatically affect the durability of asphalt by enhancing its resistance.  

“By using less asphalt, our discovery may have dramatic results on reducing CO₂ [carbon dioxide] emissions.” 

The third-party testing aims to determine the most effective ratio for ease of use, mechanical strength, thermal stability, and overall durability.

The identification of this ratio could result in annual savings of billions for national, state, and local governments by reducing road maintenance costs and extending the lifespan of infrastructure. 

Once the optimal mix ratio is established, Premier Graphene plans to collaborate with road construction companies.  

The partnership will focus on constructing specific road sections in extreme weather conditions and high-traffic areas using graphene-enhanced asphalt.  

Long-term monitoring of these roads is expected to provide data on the material’s performance and benefits. 

In April this year, Premier Graphene showcased its progress in integrating graphene with construction materials through in-house studies.  

The company highlighted the potential of graphene-infused concrete to offer increased resistance, strength, and faster curing times, which could reduce costs for large-scale construction projects.
