LL-TEQ™
Environment
No bitumen. No heating. No asphalt plant. No acute aquatic toxicity — confirmed by EPA-method testing.
Carbon impact
A process that eliminates the main sources of emissions
A fundamentally different process
Roads built without burning anything
Traditional road construction relies on petroleum-based binders, high-temperature processes and heavy logistics that generate significant CO₂, fine particulates and volatile organic compounds.
LL-TEQ builds or rehabilitates roads using the materials already on site — without bitumen, without heat, without combustion. It removes the three largest carbon contributors of conventional road construction in a single step: bitumen heating, asphalt-plant logistics and long-distance material transport.
The result: a road that is engineered to last decades, built by working with the environment — not against it.
Water safety
Acute aquatic toxicity not detected under EPA methods
Independent testing performed by Coastal Bioanalysts, Inc. (VELAP #460030, EPA #VA01116 accredited laboratory) under EPA Methods 2000.0 and 2002.0, on simulated runoff from LL-TEQ-treated road material. The applied EPA methods are equivalent to the Canadian ECCC EPS 1/RM/21 and 1/RM/22 protocols (Whole Effluent Toxicity, Environment and Climate Change Canada). No statistically significant lethality was observed for either freshwater species, even at 100% undiluted runoff.
Built next to the Bay
Selected for direct proximity to a protected ecosystem
Ravenswood Trail (Bedwell Bayfront Park, Menlo Park, California, May 2024): 40,000 sq. ft. of multi-use trail built inside a nature reserve adjacent to San Francisco Bay. LL-TEQ was selected for its acute aquatic toxicity profile — not detected under EPA methods — to protect native birdlife and the aquatic species of the site.
Beyond aquatic safety, the treated layer exhibits very low permeability (k = 3.6 × 10⁻⁸ cm/s, ASTM D5084) — roughly an order of magnitude below the untreated soil — limiting the migration of pollutants toward the groundwater. At the end of its service life, the pavement can be cold-recycled in place and re-stabilized with a fresh LL-TEQ dosage, rather than sent to landfill.
Environmental certifications
Independent assessments — multiple jurisdictions
- WHMIS (Canada) — per the manufacturer MSDS: all components are listed on the DSL (Domestic Substances List) or below the NDSL reporting threshold. Not classified as a hazardous material under WHMIS 2015. Not regulated under TDG (Transportation of Dangerous Goods).
- EPA methods equivalent to ECCC — acute aquatic toxicity testing (Coastal Bioanalysts, 2013, VELAP #460030, EPA #VA01116 accreditation) under EPA Methods 2000.0 and 2002.0, equivalent to the Canadian ECCC EPS 1/RM/21 and 1/RM/22 protocols. No statistically significant lethality to Ceriodaphnia dubia or Pimephales promelas; LC50 > 100%.
- OSHA / TSCA (United States) — not classified as a hazardous chemical under 29 CFR 1910.1200. All components are listed under TSCA. Not classified as RCRA hazardous waste. Not regulated under US DOT or IATA.
- U.S. Fish & Wildlife Service (2017) — site-specific approval for use in Alabama beach mouse (Peromyscus polionotus ammobates) habitat, a protected species.
- Tennessee Valley Authority (TVA) — soil supplied by TVA for the 2013 aquatic toxicity testing program (Coastal Bioanalysts).
Deployed in sensitive environments
Used near bays, rivers, forests and farmland
Since 2012, the technology has been deployed across 39 countries — including coastal zones, marine environments, farmland, forested areas, and protected biodiversity habitats. The Ravenswood Trail (Menlo Park, California, May 2024) was built directly along the edge of San Francisco Bay, inside a nature reserve. The UNRA pilot project (Lira, Uganda, April 2012) has been monitored under tropical high-rainfall conditions for several years — still in service.
Lower carbon. Safer water. Same road that lasts decades.
