Road Rehabilitation and Preventative Maintenance
The County maintains more than 1,100 kilometres of roads, excluding private lanes and provincial roadways including Highway 62 and parts of Loyalist Parkway. Maintenance decisions are guided by provincial standards set out in the Ontario Minimum Maintenance Standards for Municipal Highways, O Reg 239/02. Each year, staff develop a road rehabilitation and maintenance plan and capital project budget, which Council reviews and approves.
Learn more below about the techniques the County uses to improve roadways and extend the lifespan of these important infrastructure assets.
Double Surface Treatment
Road sections that are at or near complete failure must be fully rehabilitated. A low-cost option is to pulverize the road, re-grade with added granular and apply a double surface treatment. Some site works such as culvert replacements or ditching may be required depending on the project.
Phase 1 – Road Allowance Preparation: April and May
Culvert replacements, minor ditching, brushing
Phase 2 – Road Surface Pulverization: Late May
Road surface will be pulverized with grader and compactor following the operation
Phase 3 – Road Surface Preparation: Following pulverizing operations, extending to late July
New granular material will be added to the pulverized surface with the grader and compactor
Phase 4 – Double Surface Treatment Application: August
Two layers of surface treatment with a final layer of fog seal.
Frequently Asked Questions
Double surface treatment is a cost effective and durable construction technique for roadways at or near the end of their lifespan.
After the road is pulverized and prepped, double surface treatment is applied. A uniform layer of asphalt emulsion is applied with a distributor truck followed by a spreading machine to apply a layer of cover aggregate. This is immediately followed by compaction machines / rollers to set the aggregate into the emulsion. This process is repeated to form the surface layer of the double surface treatment.
The municipality has included fog seal in the process for double surface treatment, which is applied after the top layer of surface treatment. A layer of hot emulsion is applied by a distributor truck followed by a spreader applying sand. The fog seal will set before opening to traffic. The fog seal will seal the road surfacing and help decrease stone loss.
Work will typically involve minimal amount of disruption to residents as all works are mobile operations. Driveways may be momentarily blocked during activity directly in front of your property.
During construction, the road will remain as a loose-top (gravel) surface for a period of time. This will result in more dust than experienced with your current hard-top (surface treatment) surface.
The municipality will take all reasonable measures to provide dust control during this time. Decreasing your driving speed will reduce the amount of dust created.
Road construction is permitted Monday-Friday (excluding holidays) between 7 am and 7 pm.
Weekend work will only be permitted for the contractor(s) with approval from the municipality. Notifications will be issued in this situation.

Single Surface Treatment
Single surface treatment (SST) is a preventative maintenance technique used on roads in good condition or those that have previously been double surface treated. SST preserves and reinforces the existing road surface, therefore extending its life expectancy, while also creating a new waterproof barrier and restoring the skid resistance on the roadway.
A uniform application of asphalt emulsion is sprayed on the existing road surface by a computerized distributor truck. A uniform layer of cover aggregate is then applied using a chip spreader machine. This is immediately followed by two rollers that set the aggregate into the asphalt emulsion. The aggregate will continue to set with warm weather and traffic volumes.
The road may have a granular appearance immediately following application; however, as it continues to set, the surface will turn darker. Line painting will be reinstated, where applicable, after that material has set sufficiently.
Micro surfacing is a road rehabilitation technique used to extend the life of the roadway. The application of micro surfacing seals the road to prevent water from infiltrating the road base to reduce deterioration. The technique creates a road surface that is coarser texture for enhanced skid resistance and a safe wearing surface.
The micro surfacing process includes a mixture of materials (emulsified asphalt, aggregate, filler, water and additives) that are proportioned, mixed and spread with a specialized machine. Two lifts of micro surfacing will be completed on most roadways. Following a short curing period, traffic is provided access onto the new surface.
Micro surfacing application will take place in early summer and be completed in early July. Line painting will be reinstated, where applicable, after that material has set sufficiently.
Crack sealing is a preventative maintenance technique. Cracks are filled with flexible material that bonds to the existing asphalt and prevents the intrusion of water and debris into the crack, protecting the road from further deterioration. Studies have shown that 75 per cent of unsealed cracks develop into potholes within three years, while only 1 per cent of sealed cracks develop into potholes within three years.
Existing cracks are cleaned using compressed air. The filling material is heated in a kettle and injected into the cracks. Following the application, a barrier material is applied to prevent tracking and allows almost immediate access to traffic following the application.
Crack sealing application will take place early summer and is expected to be completed by early July. Line painting will be refreshed shortly after the application of material.
