Types of Paving Repairs

Patching is the go-to solution for asphalt paving repairs Adelaide. Quickly filling potholes helps stop further pavement erosion while cutting costs with time-intensive, disruptive repairs.

Linear cracking (or longitudinal cracking), is the formation of long, straight cracks running along the pavement surface or roadway surface. They may occur as a result of asphalt shrinkage, temperature changes or poor construction techniques.
Class A

Patching – Filling potholes and excavated areas quickly helps minimize further deterioration, delay more expensive repair options, and save money. Crackfilling involves placing material into non-working or low movement cracks to block moisture entry to the subgrade and cause erosion of pavement surfaces.

Skin patching (also referred to as surface patching) is a temporary repair method designed for winter or extreme weather conditions, often applied prior to milling and paveing a parking lot.

Pavement rutting is caused by compression of surface layers and/or insufficient compaction during installation, and further compounded by traffic. Class A rutting, for instance, manifests itself by depressions in asphalt that become evident during rainfall showers; such damage can be repaired using cold mills, overlays, infrared patches or infrared patches. Line painting involves marking pavement with directional arrows, disabled parking symbols and parking stalls to enhance curb appeal while fulfilling ADA code compliance – we use only high quality line painting materials to achieve this result!
Class B

Asphalt overlay is an effective and affordable method of revitalizing pavement that remains structurally sound yet requires resurfacing. This process involves applying a fresh layer of asphalt on top of existing one to add strength or improve aesthetics; milling may or may not be required depending on its condition and road or surface condition.

Class B partial-depth pavement repair employs asphalt rather than concrete when resurfacing projects are in excess of three inches deep. This repair type may also be employed on full depth or composite (AC over PCC) pavements which have spalling, delamination or surface spalling but without significant reflective cracking issues.

Edge cracks are long, V-shaped cracks that appear along the outside edges of paved surfaces and are caused by poor drainage, heavy vegetation along the edges or excessive traffic. In order to repair edge cracks effectively, tack coating or grinding should be performed to ensure adhesion between new patches and the old patches.
Class C

Class C asphalt surface repairs target damage localized to one area of an asphalt surface and is intended as a short-term fix to help mitigate further degradation until more permanent solutions can be completed. Examples of Class C repairs are crack filling, patching and rutting.

Linear cracking is a type of wear and tear found on asphalt pavement that appears as long, straight lines. This condition may be brought on by daily temperature fluctuations, soil shrinkage and weak points in pavement joints; prevention methods usually include repairing edges of asphalt roads, improving drainage around them and clearing away vegetation that might cause root intrusion.

This type of paving repair entails sealing and filling existing cracks in your asphalt surface layer with hot rubberized joint sealant that meets federal specifications, then filling them in with light aggregate material to increase adhesion. It’s an affordable, quick, and temporary repair solution.
Full Depth

Sometimes basic resurfacing alone won’t suffice when it comes to protecting the asphalt at an industrial facility. When damage has reached all the way to its core layer, full-depth reconstruction may provide the more effective and long-term solution.

Under this technique, old asphalt and base materials are ground into a uniform consistency using specialized machines before mixing with various stabilizing additives like lime, fly ash, or asphalt emulsions for stabilization. After that step is completed, the mixture can then be graded and compacted to form a new base that’s stronger than ever.

Throughout the construction process, regular visual observations are essential to monitoring equipment and ensuring it is functioning effectively. Pulverizer temperatures, moisture requirements and asphalt emulsion temperatures must all be strictly managed to produce top quality results. Steel mesh repairs of over 10 feet long must also be strengthened using full depth reclamation in order to provide strong patches that last over time.
