Pothole Partnership Programme Process Overview
PREPARATION
Once the pothole has been identified, the area surrounding the damage will be carefully marked and cut to form a clean, uniform square or rectangular shape. This process involves removing all loose debris, weakened asphalt, and irregular edges to create a stable boundary for repair. By reshaping the pothole into defined geometric edges, the filling material can be placed more accurately, compacted more effectively, and bonded more securely to the existing pavement structure. This preparation step is crucial for achieving a durable, long-lasting, and structurally sound pothole repair.
BLOWING
After the preparation work is completed, the shaped pothole will undergo a thorough cleaning process. A high-powered blower will be used to remove all dust, loose aggregates, and remaining debris from the cavity. This step is essential because any residual particles can interfere with the bonding of the repair material, reducing adhesion and compromising the durability of the patch. Ensuring a completely clean surface helps achieve a stronger, longer-lasting, and more uniform repair.
FILLING
After the cleaning and blowing process is completed, a uniform layer of asphalt tack coat is sprayed over the prepared pothole cavity. This bonding agent is essential, as it helps the new material adhere securely to the existing pavement. Once the tack coat is properly applied, the repair material is poured into the cavity in controlled layers. The material is then spread evenly across the entire area to ensure that all voids are filled and that the surface is level. This careful placement and distribution of the material are critical for achieving a durable, stable, and long-lasting repair.
CONDENSING
Once the cavity has been filled with the required repair material, the mixture is carefully levelled and evenly distributed across the entire prepared area to ensure uniform coverage. After achieving an even spread, a mechanical compactor (condenser) is employed to compress the material firmly into the cavity. This compaction process is essential, as it removes trapped air, increases material density, and promotes strong bonding between the new material and the existing pavement structure. Proper compaction ensures that the repaired section attains the necessary strength, stability, and durability to withstand traffic loads and environmental conditions over time.
BRANDING
After the pothole has been properly filled and compacted, the final step involves carrying out the required branding or marking. This typically includes applying identification labels, markings, or company branding on or near the repaired section, ensuring proper documentation and visibility of the completed work.
