Why LL-TECH
Installation Process
LL-TECH integration procedure — fast, precise, and in a single pass
One-Pass Technology
Standard equipment, exceptional results
LL-TECH integrates directly into standard road construction methods. Using a cold recycler and stabilizer, product integration at the required depth is performed in a single pass, ensuring homogeneous mixing, high execution precision, and increased efficiency.
Once the recycler pass is complete, the grader and compactor can intervene immediately. Sealing layers finalize the structure. Production rate: 2 to 4 km per day with a single reclaimer, once the crew is familiar with the process. The rate depends on treatment width, target depth, and site conditions.
Step-by-Step Process
Five steps to a durable road
Mill & Mix
The cold recycler mills the prescribed thickness of in-place material — asphalt, soil, or aggregate — while injecting the LL-TECH solution from a tanker truck in a controlled, continuous manner. Objective: homogeneous mixture at optimum moisture content (OMC).
Initial Compaction
A roller compactor provides initial compaction to stabilize the treated material and limit displacement during grading. Critical step for final structural performance.
Grading
A grader grades the treated material to achieve the profile and slopes required by project specifications — ensuring geometric compliance before final compaction.
Final Compaction
Final compaction to a minimum of 95% of standard Proctor density (moisture content near OMC) using a roller compactor. Reopened to traffic in 12 to 36 h under favorable conditions. The delay depends on material type, ambient temperature, and weather conditions. High-plasticity soils may require additional time before traffic reopening or surface treatment application.
Sealing Layer
The sealing layer is applied with a tanker equipped with a rear spray system. May include pigmentation. Can begin immediately after compaction depending on aggregate gradation.
Equipment Used
Standard machinery — no special imports
Cold Recycler / Reclaimer
Performs milling, mixing, and product injection in one pass. Standard rental equipment used globally.
Motor Grader
Profiles the surface to specified slopes and grades. Standard construction equipment.
Roller Compactor
Achieves minimum 95% of standard Proctor compaction (near OMC) for structural integrity. Standard vibratory roller.
Water / Product Tanker
Supplies LL-TECH solution diluted in water to the recycler. Enables controlled, continuous injection.
Performance Rates
Up to 4 km per day
Production rate: 2 to 4 km per day with a single reclaimer, once the crew is familiar with the process. The rate depends on treatment width, target depth, and site conditions. Reopened to traffic in 12 to 36 h under favorable conditions; the delay depends on material type, ambient temperature, and weather conditions, and high-plasticity soils may require additional time.
No asphalt plant. No material import. No heating. No fumes.
Performance values reported are based on specific test conditions and may vary depending on project context.
Reference Section
Reference section (pilot project)
LL-TECH is validated in laboratory and field across 39 countries — on the same materials found in Quebec: RAP, aggregates, clay, silt, sand. Testing was performed by independent laboratories in the United States and Australia under ASTM and AASHTO protocols, and in France under current NF standards. Engineering parameters are universal — a CBR is a CBR, a Proctor is a Proctor, whether the soil is from Illinois, Brittany, or Montérégie.
What the industry calls a "pilot project," we call a reference section. The technology is no longer experimental — it has been deployed for over a decade under U.S. military aircraft and on the roads of 39 countries. Solecovia offers this reference section on preferential terms for new partners, to create a visible, measurable local benchmark. Our engineers and technicians provide on-site support to ensure technical compliance and skill transfer to local crews — although the process uses standard road-building equipment and methods.
