Pavement Preservation & Road Rehabilitation

PAVEMENT PRESERVATION & ROAD REHABILITATION

Maximizing Value

Proudly Serving Ontario Since 1988

Pavement preservation is a cost-effective, sustainable approach that extends the lifespan of roads while maximizing the value of taxpayer dollars. Unlike conventional road rehabilitation methods, pavement preservation techniques are designed to maintain and protect existing pavement in good condition for as long as possible, delaying the need for costly full reconstruction.

In addition to delivering significant cost savings, a well-planned pavement preservation strategy has notable environmental benefits. It typically generates fewer greenhouse gas emissions, consumes less energy and raw materials, and allows for quicker application times—reducing disruption to road users and the community.

Our Promise

When implemented effectively, pavement preservation increases the average condition of your road network while lowering the average cost per square metre. This means municipalities and road owners can maintain more kilometres of road to a higher standard, using fewer resources and delivering greater value for every tax dollar spent.

Cost-Effective Longevity

Pavement preservation stretches the lifespan of roads while maximizing every taxpayer dollar spent.

Eco-Friendly Practices

Preservation methods produce fewer greenhouse gases and use significantly less energy and raw materials.

Faster, Less Disruptive

Thin surface treatments allow for traffic to return shortly after placement, reducing lane closures and minimizing traffic interruptions.

Limited budgets mean that spending on infrastructure is not keeping pace with current needs. Roadways are constantly deteriorating and the finances necessary to continually rebuild them are not available. The need for cost effective pavement preservation strategies is immediate. Duncor provides Thin Surface Treatments to help meet this need.

Thin Surface Treatments are also ecologically and socially responsible pavement preservation tools. Surface Treatments use fewer raw materials and produce significantly less green house gases than conventional mill and pave operations. Micro-surfacing for example emits approximately 80% less CO2 and uses approximately 80% less aggregate than a typical asphalt overlay.
