Reinventing Road Construction

LL-TECH is a pavement structure technology developed by LANDLOCK and distributed and deployed by SOLECOVIA.

It has been validated and implemented on civil, industrial and military projects, including infrastructure approved by the United States Army, which is recognized as one of the most demanding compliance frameworks in the world. LL-TECH makes it possible to build pavement structures directly from in-place materials, as a structural alternative to traditional asphalt pavements.

The structural layer created by LL-TECH provides high load-bearing capacity and very low permeability, limiting water infiltration, protecting the pavement structure and significantly reducing damage associated with freeze–thaw cycles.

Depending on site conditions, traffic can be restored quickly, often within 24 to 48 hours, without bitumen, without heating and without harmful emissions.

Roads are the arteries of a territory

Road infrastructure carries resources, connects communities and supports the economy. When these arteries weaken, costs surge, interventions multiply and regions become isolated.

Our mission is simple: to deliver roads that are faster to build, more durable and more stable, through an approach that reduces logistical constraints and the environmental footprint associated with traditional methods.

Complete structural innovation for pavement

LL-TECH replaces asphalt-based logic with a monolithic, dense and water-resistant structure.

The technology stabilizes and binds granular materials and soils to create a pavement designed to last for several decades, including under heavy traffic and in severe climatic conditions. Designed as a complete structural system, it is installed without asphalt or heating.

Deployed internationally in more than 35 countries, LL-TECH has been used for road projects as well as military, industrial, mining and logistics infrastructure, where structural performance is a fundamental requirement.

What sets LL-TECH apart

  • Rapid implementation: reduced construction timelines.
  • Optimized logistics: less material importation and reduced heavy transport.
  • Structural performance: a stable, durable and water-resistant layer.
  • Climate resilience: performance maintained in wet and hot conditions and through freeze–thaw cycles.
  • No-heating process: no thermal impact associated with installation.
  • Bitumen-free formulation with integrated UV protection, designed to limit aging caused by sun exposure.

Verifiable technical evidence

LL-TECH is supported by rigorous technical documentation, standardized testing (ASTM, AASHTO) and multi-year field observations.

Available reports document:

  • Mechanical strength,
  • Resistance to water and moisture,
  • Stability under repeated loading,
  • And durability in severe climatic conditions.

Environmental aspects are also supported by specific testing demonstrating the safety and stability of the treated materials.

Concrete, field-proven applications

  • Municipal and regional roads (urban and rural).
  • Industrial, forestry, agricultural and mining access roads.
  • Logistics platforms and maneuvering areas.
  • Aeronautical and military infrastructure (based on documented projects).

A technology designed for in-place materials

Whether using granular materials, gravel, natural soils or on-site recycled asphalt, LL-TECH maximizes the use of existing materials and limits importation.

It integrates seamlessly into rehabilitation projects as well as full reconstructions, with structural performance designed to remain stable despite water exposure and seasonal variations.

SOLECOVIA makes it possible to break away from the repetitive asphalt cycle by deploying LL-TECH technology to build road infrastructure that is durable, high-performing, proven and environmentally responsible, even in the most demanding contexts in the world.
