The cost of a road starts with the ground.

Its true value is measured throughout its working life.

Why build this road? To transport what, how often, for how many years — and with what consequences?

Facts first · accessible sources

Ground conditions change the cost of a road.

Documented projects in northern settings illustrate how ground conditions, remoteness and construction requirements affect costs.

≈ CAD 3.81 M/km

CAD 25.5 M in funding for the 6.7 km first phase of a two-lane all-season road. Ratio of announced funding, not a final construction cost.

Far North gravel roads

A historical estimate from 2017 cited in the 2022 report for all-season gravel roads in the Far North. This benchmark is not a current market average.

Slave Geological Province

≈ CAD 2.66 M/km

Approximately CAD 1.1 B for a proposed 413 km corridor, giving an indicative ratio. This is a regional infrastructure concept, not a road constructed at that cost.

Academic analysis ↗

Another benchmark: the Northern Policy Institute reports a 2019 quote of CAD 550,000 to 800,000/km for a timber-mat road in a northern setting. This technology differs from XtremeM; it is not an equivalent-scope technical price comparison. Read the study ↗

A completed road must also support efficient operations.

During the first seasons of use on a forest road, driving conditions can vary considerably with the soil, drainage and rainfall. Mud, rutting and surface deformation may require grading or additional materials while slowing vehicles down. This stabilization period therefore carries a real cost: additional maintenance, slower deliveries and occasional access disruptions. Comparing solutions means considering not only construction, but also road availability and operational efficiency from the moment the road enters service.

01 — A different perspective

A road is a production asset.

We do not choose machinery on purchase price alone. Why choose a road without considering truck productivity, reliability, maintenance and residual value?

Build

Clearing, excavation, foundations, aggregates, transport and drainage.

Operate

Fuel, haul cycles, truck wear, maintenance and interruptions.

Address the impacts

Hydrology, habitats, permits, restoration and climate risks.

What value do we place on what the construction price does not measure?

02 — Ground conditions matter

A kilometre is almost never uniform.

Bearing capacity, water, freeze-thaw cycles and transitions between soils determine the work required and the maintenance risks.

RockGood bearing capacity; excavation may be needed
SandOften favourable; erosion is possible
SiltSensitive to water and frost
ClayVariable settlement and bearing capacity
Mixed soilsLocalized weak points
PeatlandLow bearing capacity, water storage
SwampSensitive flows and habitats
PermafrostRisk of subsidence on thawing

Load distribution through the assembly is assessed against loads, ground support and traffic cycles.

03 — Water is part of the project

A road crosses a watershed. Water flows across the landscape.

Embankments can interrupt diffuse flows. Ditches can concentrate water towards a few culverts. Watershed management must consider the cumulative effect of roads, not just each culvert in isolation.

Designing access around water

Traditional road

Embankments, ditches and culverts shape road drainage. Their design must account for natural flows, expected flow rates and downstream effects.

Targeted modular intervention

XtremeM modules can be positioned on sensitive sections to limit earthworks and preserve diffuse flows where site conditions allow. Bearing capacity, crossings and drainage still require project-specific design.

The real issue is not to eliminate all hydraulic management: it is to design access that disrupts watershed functions as little as possible. Watercourse crossings and concentrated flows require specific design.

Depending on ground conditions and loads, a modular configuration may reduce excavation, imported aggregates and longitudinal drainage works. Site preparation and required structures must still be defined for each location; no quantified hydrological benefit or zero-impact outcome is assumed.

04 — The research

Road quality changes the economics of transport.

13%

Fuel

Savings of up to 13% simulated in the independent study by Maior et al. (2025), for a mining-road case in Brazil.

17%

Productivity

A gain of up to 17% simulated per truck in the same study, with cycles up to 15% shorter.

Up to CAD 3.5 B/year

Climate and roads

Potential annual increase in road maintenance and repair costs in Canada by 2050, presented to the Senate in 2023.

Results from specific studies and projections, not measured XtremeM performance. They explain why operations and risks belong in the decision, without being automatically applied to the calculator.

05 — The essential questions

What does the quotation leave out?

A day of access?

What production cost follows an unexpected closure?

One haul cycle?

What are the minutes, fuel and wear avoided worth?

A functioning watershed?

What value do preserved hydrological functions have?

A month gained?

What is the benefit of earlier commissioning?

A smaller footprint?

Which studies and mitigation measures are needed? Faster permitting is not guaranteed.

A second use?

What will recovery and redeployment cost? What value remains in the modules?

06 — The right tool in the right place

The best road may be hybrid.

Stable ground: a traditional road may be optimal. Variable ground: XtremeM modules can target difficult sections. A hybrid configuration therefore combines a conventional road with modules in strategic locations; hydrological management is a complementary area for study.

We do not aim to replace every road. We aim to address the sections where conventional construction becomes costly or damaging.

07 — Exploratory calculator

Compare 15 years of service, not just day one.

An initial economic view of the same access road operated for 15 years, without redeployment, with removal and site restoration in year 15. If the road stays in service, adapt end-of-use costs and terminal values. Amounts are editable: these assumptions are neither quotations nor guaranteed performance.

Annual amount supported by your scenario. Do not combine opportunity revenue and avoided hourly costs for the same hours.
Project amount at the end of year 15. Not automatically multiplied by kilometres.
Project amount at the end of year 15, separate from site restoration.
Site works after removal, without counting module removal twice. No zero-impact assumption is made.
Total terminal value deducted in year 15. Zero by default in this restoration scenario; adjust if the road stays in service or retains recoverable value.

Brings constant-currency expenditure and final value to a common date. The 6% assumption is retained from the supplied scenario; 0% gives an undiscounted view.
