Traditional road rehabilitation methods rely on a repetitive cycle: milling, transport, heated asphalt mixes, followed by resurfacing a few years later. This model is energy-intensive, polluting, and structurally limited by asphalt’s sensitivity to water and aging.

LL-TECH deployed by SOLECOVIA offers a fundamentally different approach. It makes it possible to replace the asphalt structure by directly reusing existing materials, without massive extraction or the addition of bitumen.

Principle of intervention

• In-place crushing and mixing of existing materials (recycled asphalt, aggregates, soils).
• Creation of a monolithic, dense, and impermeable structure.
• Cold process, without heating, without fumes, without harmful emissions.

Key benefits

• Reduction of more than 90 % in heavy logistics (transport, materials, fuel).
• Major reduction in VOC, PAH, and CO₂ emissions.
• Reopening to traffic possible within 24 to 72 hours depending on conditions.
• Observed durability exceeding 12 years, without resurfacing or measurable deformation.
  

This approach makes it possible to permanently break free from the asphalt degradation cycle and to provide communities with road infrastructure designed to last.
