WHAT IS IT?
“Crack filling” refers to the process of filling or sealing cracks or fissures in a paved surface, such as a road, highway, parking lot, or sidewalk. This procedure is carried out to prevent existing cracks from widening over time due to exposure to the elements and traffic, which could lead to more serious issues with the paved surface.
Repairing asphalt pavement is often necessary due to natural wear and tear over time and damage caused by factors such as traffic, weather conditions, tree roots, water leaks, and other external agents. Asphalt patches are specific areas where damaged or deteriorated asphalt is removed and replaced to restore the surface to its original condition.
Steps of crack filling
Crack filling is typically done using a sealing material, which may be an asphalt-based compound or a similar substance. The process involves the following steps:
Cleaning the crack
Before applying the sealer, it’s important to clean the crack of any dirt, debris, or moisture that may be present. This ensures better adhesion of the sealer to the crack’s walls.
Preparation of the sealer
The sealing material is prepared according to the manufacturer’s specifications. It can be in liquid form or solid form, depending on the type of sealer used.
Application of the sealer
The sealer is poured or applied into the crack to fill it completely. It can be applied hot or cold, depending on the type of sealer and the surface conditions.
Compaction and smoothing
After applying the sealer, a suitable tool, such as a trowel or squeegee, may be used to compact the material and smooth the surface. This ensures that the sealer adheres well and that the crack is level with the surrounding surface
Crack filling is an important maintenance measure to extend the lifespan of paved surfaces and prevent more significant damage. By sealing existing cracks, it prevents water and other elements from penetrating into the pavement’s base and causing additional damage, such as pothole formation. This helps maintain the structural integrity of the surface and reduces long-term repair costs.
