Asphalt repair works when you have isolated problem areas—a few cracks, small potholes, or minor settling. If the majority of your surface is still in good condition, targeted repairs can extend its life cost-effectively. Replacement becomes necessary when you have widespread cracking, multiple potholes, or significant drainage issues. In Livingston, we often see this after 15-20 years, especially on surfaces that weren’t properly maintained or had inadequate base preparation initially. The decision usually comes down to economics: if repair costs are approaching 50% of replacement costs, or if you’re dealing with recurring problems, replacement typically makes more financial sense and gives you a fresh 15-20 year lifespan.
