What is the first step in filling a crack with asphalt?

Cleaning the crack is the first and essential step in the process of filling a crack with asphalt. This preparation ensures that any debris, dirt, or old material lodged within the crack is removed, which allows the new material to bond properly with the existing asphalt surface. If the crack is not clean, the filling material may not adhere well, leading to an ineffective repair that could allow moisture and debris to penetrate, potentially causing further damage. Proper cleaning often involves using a wire brush, compressed air, or a vacuum to ensure the area is fully prepared for the application of the asphalt filler. This foundational step is crucial for achieving a durable and long-lasting repair in asphalt surfaces.
