Several indicators suggest asphalt repair is necessary. These include alligator cracking, which appears as interconnected cracks and indicates structural issues; potholes caused by water infiltration; rutting in wheel paths due to heavy loads; raveling, where the surface aggregate becomes loose; and edge or block cracking resulting from aging or inadequate support. Additionally, depressions or areas that collect water, often called 'birdbaths,' may point to subgrade problems. Addressing these issues promptly can prevent further damage and avoid the need for costly full replacement.
