What does the process of crack sealing aim to achieve?

The process of crack sealing primarily aims to prevent water ingress and further damage to pavements. When cracks form in the surface of pavement, they can allow moisture to seep into the underlying layers. This moisture can lead to a variety of problems, such as freeze-thaw cycles which exacerbate the cracks, erosion of the base material, and ultimately, more significant structural failures. By sealing these cracks, the procedure prevents water from entering the cracks and causing additional damage, thereby extending the lifespan of the pavement and improving its overall integrity.

The focus on preventing water ingress illustrates the importance of maintenance in public works, as it aligns with the broader goal of preserving infrastructure assets in a cost-effective manner.
