Proven structural stability under real-world conditions
Freeze–thaw cycles are one of the primary causes of premature deterioration of traditional road infrastructure. Water infiltration into the structure, followed by expansion during freezing, leads to cracking, rutting, loss of bearing capacity, and repeated interventions.
LL-TECH technology was developed to address this structural issue. By transforming in-place materials into a dense, cohesive structure with very low permeability, it limits water migration within the pavement structure and sustainably stabilizes bearing capacity, including under saturated conditions and repeated thermal cycles.
Validated performance
Independent testing conducted in accordance with ASTM and AASHTO standards, including Hamburg Wheel Tracking and MMLS tests, demonstrates:
- high resistance to rutting under immersion,
- no cracking under repeated cycles,
- mechanical stability maintained after thousands of load passes.
These results are directly related to freeze–thaw performance, as winter deterioration results precisely from the combined action of water, freezing, and repeated loading.
Field performance in cold climates
The performance of LL-TECH technology has been observed at numerous sites exposed to recurrent winters, annual freeze–thaw cycles, and prolonged moisture conditions, both in North America and in Europe.
Unlike traditional asphalt structures, no freeze-related structural degradation has been observed at the evaluated sites after several full winters of operation.
These findings demonstrate a road infrastructure that remains stable over time, capable of withstanding the most demanding climatic conditions without heavy maintenance.
Laboratory validation
Hamburg Wheel Tracking tests confirmed high mechanical resistance under severe test conditions. Stabilized specimens withstood 20,000 wheel passes under immersion, with limited deformation.
