Many municipalities have a pothole patching program that is not based on a solid pavement repair strategy. Instead of addressing the underlying and surrounding issues that create the potholes, these programs focus on throwing asphalt at the problem. This can lead to a quick fix that is easily undone by heavy traffic. This article looks at how a more thorough process can save both labor and equipment costs and allow for a more sustainable tarmac pothole repair.
The first step in the tarmac pothole repair process is to clear the area of any debris, then backfill with cold-lay tarmacadam at the appropriate depth and compact it using either a mechanical tamper or lawn roller. Consolidation is the key to making sure that the tarmacadam will set properly and not break loose. A vibrating plate is ideal for this work, but a club hammer with a block of wood is suitable if the budget does not allow for the purchase of this tool.
From Driveways to Highways: Addressing Pot Hole Repairs
Once the tarmacadam is in place, a cold joint spray sealant and over-banding tape can be applied to complete the pothole repairs. HAPAS-approved products like Ultracrete SCJ spray and Instaband Eco are excellent choices for these applications.
In addition to these essential products, a tarmac restoration product such as Nuproof can also help in the long-term maintenance of a pothole repair. This product is specifically fomulated to rejuvenate tired old tarmacadam and can be used on different aggregate gradings. It is available in a tin or in a powder format.
