The world's most essential infrastructure is rebuilt using a process that is costly, inefficient and unchanged for a century
Conventional road rehabilitation relies on hot mix and warm mix asphalt (HMA and WMA), materials produced at centralized plants and trucked to every jobsite. That dependence creates six distinct challenges for the road networks global economies run on.
Quarry
Mining of virgin stone aggregate and hauling to plant
Bitumen
Petroleum binder hauled a plant for processing
Plant Heating
Heated to 300°F+
and mixed
Hauling to Site
Hot mix trucked from plant to site ~400 trips
per lane-mile
Waste Surplus
Asphalt millings are hauled away from site
High Emissions Baseline
Conventional asphalt paving projects require five separate carbon-intensive operations before asphalt touches the road.
Conventional methods like Hot Mix Asphalt (HMA) and Warm Mix Asphalt (WMA) dominate the industry, and can only incorporate up to 25% of the existing road.

Life extension
Failed Roads Qualify
Cold recycling is a reconstruction method, not a maintenance treatment. The road must have reached the end of its structural life, where resurfacing and repair are no longer effective solutions.
Mill and Remove Aged Asphalt
A cold recycler pulverizes the existing asphalt and base layers into loose material in a single pass. The failed road becomes the raw material for the new one, processed entirely on site.
Material Processed
The pulverized material is processed into a uniform, engineered mix. This becomes the structural base of the reconstructed road, with no new aggregate required.
Rejuvenated and Remixed
A binding and rejuvenating agent is introduced into the reclaimed material, reactivating the old binder and transforming it into a structurally stable base layer without heat.
Compacted and Installed
The finished cold mix is laid directly behind the recycling train and compacted by a roller close behind. Traffic reopens within hours. About one lane-mile per 10-hour workday, two to three times the rate of conventional repaving.
Circularity
100% material reuse
Existing pavement becomes structural feedstock. No quarry expansion, no virgin aggregate. The road regenerates itself.
Air Quality
Zero plant VOC emissions
Ambient-temperature process, no plant heating, no stack emissions, no community exposure to volatile organic compounds and diesel particulate.
GHG Emissions
Avg 60% reduction
88-146 tCO₂/lane-mile baseline collapses to 38-125 depending on technique. Verified under VM0039.
Community Health
Less HMA plant reliance
Fewer truck trips through burdened neighborhoods. Reduces dependence on the 3,600 HMA plants disproportionately sited near vulnerable communities.
Speed
1 mile per day production
Same-day reopening. Communities aren't displaced by construction for weeks. Freight isn't rerouted across the network.
Cost
~45% project savings
Resurfacing ~$330K/lane-mile drops dramatically. Cold recycling stretches limited DOT budgets across more lane-miles per dollar.
742 road segments across 5 verified projects in 24 states
Road reconstruction projects across public and private networks, from national parks to urban corridors, each delivering lower costs, fewer truck trips, extended road life, and emission reductions verified under the Verified Carbon Standard through VM0039, the first methodology of its kind.
