Installation

One technology, two installation methods

Rebuild the pavement from materials already on site, or seal an existing surface. The right choice depends on road condition, traffic loads, and target service life.

Rebuild LL-TEQ reclaimer integrating polymer into the existing pavement

New road from existing material

Cold in-place recycling. A reclaimer scarifies the existing pavement and base 100–150 mm deep, then integrates the LL-TEQ polymer into the pulverized material — no plant, no long-haul transport, no heating.

Surface seal LL-TEQ topical seal applied via spray-bar water truck

Sealing of an existing surface

Topical application. LL-TEQ is sprayed onto a shaped and compacted surface using a spray-bar water truck — penetrating 25–40 mm to bind fines, shed water, and stop dust at the source.

LL-TEQ advantages

What sets LL-TEQ apart

Three numbers tell the story — strength, speed, and water-tightness — proven in the field and the lab.

  1. 2× vs cement

    Stronger than cement stabilization

    LL30 at 4% reached 1,625 PSI on a sand-clay soil — versus 804 PSI for Portland Cement at 8% on the same soil.

    • Residual flexibilityless cracking under freeze-thaw
    • Design valueproject-specific testing per soil

    SourceASTM C39 · S.A.M. Consultants 2016 · single-specimen test

  2. 2 km+ / day · complete 2-lane rebuild

    Faster to build

    Over 2 km per day of complete rebuild — structure and wearing course, 2 lanes — with a trained crew: one pass, one reclaimer, zero plant.

    • Reopened to traffic12 h+ depending on conditions
    • Equipmentstandard road-building machinery

    Notedelay depends on soil, temperature, and weather.

  3. 10⁻⁹cm/s measured permeability

    Impermeable to water

    Hydraulic conductivity of 3 to 6 × 10⁻⁹ cm/s on treated soil — an order of magnitude below the same untreated soil. No infiltrated water: no ice lenses, no base erosion.

    • Freeze-thawless water, less ice, less damage
    • Service lifesub-base erosion removed

The process

From a worn road to a structural pavement, in one day

One site pass — no plant, no long-haul transport. Click a step to explore it.

Step 1 — Scarification

Scarification of the existing pavement

~ 1 h / km

A stabilization mill pulverizes the existing wearing course and base to the target depth — typically 100–150 mm. No material is removed: everything stays in place and is reintegrated into the final slab.

Field validation

Adopted by the U.S. military

LL-TEQ is used for tactical airstrips, forward operating bases, and logistics platforms (USMC, USAF) where rapid deployment, durability, and operational reliability are critical.

Deployed on civil, industrial, and military projects across multiple continents — field case studies documented from 2012 to 2024.

FAQ

Frequently asked questions from municipal engineers

LL-TEQ is a pavement-stabilization system made of two complementary products: LL30, a polymer binder that integrates into in-place materials (recycled asphalt, aggregates, natural soils) to create a single, dense and watertight structure, and LL25, a topical sealing coat that protects the surface. The technology is deployed in 39 countries and has been used by the U.S. military since 2012. LL-TEQ is the Québec adaptation of the system, produced here and engineered for the specific challenges of our roads: water, freeze-thaw and heavy loads.
Yes. An independent report signed by a third-party Engineer of Record in May 2026 evaluated the freeze-thaw performance of the LL-TEQ system across 9 reference sites in the United States, totalling 77 cumulative winters of service in 4 climate regimes comparable to that of the St. Lawrence Lowlands. The finding is unequivocal: 0 defects attributable to freeze-thaw observed on any of the 9 sites. No cracking, no potholes, no heaving, no rutting. The secret: LL-TEQ keeps water out of the pavement structure. No infiltrated water, no freezing expansion, no thaw creating voids — therefore no degradation.
The reference sites evaluated in May 2026 by a third-party Engineer of Record have up to 10 winters of real service with no structural defect and no defect attributable to freeze-thaw — all backed by visual inspections. How many winters an LL-TEQ pavement will then last depends on the road type, traffic volume, vehicle weight and site conditions. Because the system is not a floating surface added on top but a single, watertight structure integrated into the soil, the classic failures (cracking, rutting, potholes) that come from a water-weakened sub-base are nearly nonexistent. Light periodic surface maintenance extends the service life further.
Significant. Traditional Québec practice requires a total thickness of 550 to 950 mm (bituminous layers + base + sub-base). LL-TEQ does the same job in a single 150 mm layer, integrated directly into the soil — up to 6 times thinner.
Major. Traditional Québec practice requires a total thickness of 750 to 1,150 mm (bituminous layers + base + sub-base). LL-TEQ does the same job in a single 150 mm layer, integrated directly into the soil — up to 7 times thinner.
