Paving Repairs

Paving repairs are an essential component for maintaining a long-lasting, safe and attractive roadway surface. Neglecting to perform necessary repairs will eventually result in major issues and expensive replacements.

Early maintenance is always more economical than waiting until the pavement is severely damaged. That is why it is beneficial to regularly check your asphalt for damages and take steps to prevent them from getting worse. Look out for paving contractors adelaide south.

Crack Filling

Crack filling, or filling in a crack, is an integral part of paving repairs. It prevents moisture from seeping into the asphalt, which is one of the primary reasons why asphalt pavement deteriorates rapidly.

Additionally, it reduces the potential risk of vegetation growing in cracks, which could raise the pavement and necessitate more costly and time-consuming paving repairs.

The initial step in crack filling is to measure their width and determine if they should be filled with rubberized crack sealer or other fill materials.

To determine the width of a crack, use a measuring tape and compare its width with an established crack width guide.

Before applying asphalt crack filler, thoroughly clean the area. This includes taking out any weeds or grass that have grown in the crack and making sure it’s completely dry.


Over-banding is a widely used and successful technique for sealing cracks in pavement. This involves routing the crack and filling it with hot rubber material, which prevents water ingress and extends the life of asphalt surfaces.

Over banding can be applied in several ways to seal and protect voids up to 5mm wide. It may be applied using a road product applicator, by hand or roller following the line of cracks.

Another popular over-banding procedure involves pouring liquid substance into the crack or joint and quickly creating a wider band over it. This allows for thermal shrinkage of the sealant, which helps protect the surface by providing better moisture resistance.

Sometimes it’s essential to repair a crack in the pavement before temperatures drop and make it dry enough for cracking to occur. Colder air can cause the mat of asphalt to segregate at the surface, leading to faster degradation and increased vulnerability to leakage and water penetration.


Routing is a method that involves applying a cutting device to an existing crack, giving the hot rubber more surface area to adhere to, which could result in longer-lasting seals than non-routed ones.

Routed cracks also tend to fill in flush with the pavement, keeping them free from being caught and torn apart by shovels or snow plows.

No matter the size or scope of your surface repair or resurfacing job, D&R Paving can assist you. Our experts will assess the situation and suggest which method is most suitable for your particular undertaking.

Routing is often the most cost-effective solution when pavement with a crack density of less than 20%. Routing helps prepare the edges for sealing and may create an isolated reservoir to accommodate thermal movement over time. Aside from being an efficient idea, routing will extend your pavement’s lifespan much further than it would without it.


Patching is a small piece of asphalt placed into cracks or holes to fill them and prevent water damage to the pavement. It’s an effective repair option that’s more cost-effective than cutting away or replacing affected areas.

When patching a paving repair, there are three primary types of patching you can choose: surface patches, partial-depth patches and full-depth patches.

Surface patching is the most basic type of repair, which involves applying asphalt to damaged areas. It’s usually applied in a thin layer and then leveled off with a steel tamper to make sure it sits flush against surrounding asphalt.

Full-depth patching is a more permanent method of mending damaged areas. This procedure grinds away the top 2 to 3 inches of asphalt, replaces it with new compacted asphalt and seals the edges. However, for this method to be successful, the foundation beneath the damaged area must remain sound.

This paving pattern is popular because it is easy to install. It involves laying the pavers flat and parallel to each other, then running them at a half-offset so that the joints are centred above and below each course.

Another popular paving pattern is the Flemish Bond or Dutch bond which is made using alternate courses of headers and stretchers. The headers for the first course should be laid so that they lie in a group of stretchers from below. The stretchers for the next course should be laid so that the header of the following course is centred.
