Derek Nunn of Walker Construction provided a presentation to Council on pavement preservation options, specifically regarding the bonded wearing course product which was applied to Township roads in 2023.
Nunn spoke to the financial benefits of preserving roads, rather than rebuilding or constructing roads. The type of treatment suggested by Walker Construction for each road type and condition is intended to keep good roads good and Nunn indicated this would affect the various types of treatments they would recommend applying.
Bonded Wearing Course is an ultra-thin hot mix paving product and its application was described by Nunn. The product is used as a wear coat to extend the life of the roadway, but does not restore or improve the condition of the road.
Nunn spoke to how Walker Construction intends to facilitate repairs to the areas that were not successfully bonded during the 2023 application.
Nunn inquired of Staff whether there was an appetite to change the consistency (smoother texture) for the mix. Nunn and Staff confirmed that the rough texture of the product will naturally smooth out with use, as a natural attribute of the product. Council was not supportive of changing the consistency of a proven product.
Council noted the centre line of the road is showing seams, and inquired whether this could be improved.
Nunn confirmed that in the Spring, Walker Construction will work with staff to address areas where joints are noticeable. Nunn noted that as part of this, Council should be aware that small spots may not be feasible to correct, due to the way that repairs are made.
Walker Construction have been applying this product since 2011. With this product, the expectation is 8-12 years of extended use of the roads. Nunn confirmed that the warranty starts when the spring work is done, and will be as per the contract.
