Preparation of cracks before the repair is essential. Before they become severely damaged, crack filling can be an economical approach for preventive maintenance of asphalt pavement. The primary objective of preparing a crack is to create a dry and clean reservoir area, allowing the sealant to stick to the crack walls. The crack should be cleaned using a wire broom or wheel, ensuring a sufficient reservoir is created. Then, fill the crack with either hot or cold pour material and use a squeegee to smoothen any excess material. With a proper and timely filling, the functional lifespan of an asphalt pavement can be extended for several years.
