CRF Pavement Preservation on George and Spring Streets

Reasons for pavement preservation

The maintenance of the top coat of asphalt is a fundamental aspect of long term pavement life. This is because water is the main element that causes damage to a roadway by seeping into the roadbed through cracks and expansion/contraction during freeze thaw cycles. Inevitably, new asphalt deteriorates due to the oxidization of the asphalt cement, which leads to brittle roads that crack over time.

Options for pavement preservation

Reclamite is an emulsion that is applied to the top course of the asphalt and rejuvenates the existing asphalt cement and slows down the oxidization process. This helps to extend the life of the top course of asphalt and reduces the cracking that typically appears within five to six years after a new application. As a result, this treatment is applied to roads that are in relatively good condition and before significant cracking develops.

Typical crack sealing involves clearing out existing cracks and filling it in with a rubberized product. It is used to seal the top layer and prevent water seepage into the granular bed. CRF is an alternative treatment to typical crack sealing treatment. CRF applies an emulsion and sand product that treats the entire road as opposed to just the cracks. In addition to filling in the cracks, CRF also provides asphalt rejuvenation similar to Reclamite.

The Counties has worked with Superior Road Products in the past. Given this past experience, and recent local test results,  the Counties is trying this product again. Other adjacent municipalities and counties are already working with Superior Road Products. 

The Counties negotiation with the supplier also provides test locations for the townships and Westport.  George and Spring Streets were chosen by Westport Public Works and the product was applied on Tuesday.  There is no cost to the Village.  

Many thanks to the United Counties of Leeds & Grenville.
