Potholes in asphalt pavement are often due to changes in weather, standing water or an influx of heavy traffic. ... Cracks (less than ½" wide) – Use a crack sealant to stop moisture getting into the sub-grade layers through the cracks, and to prevent raveling of the crack edges. Follow crack sealing with a fresh application of sealcoating ...
Learn how U of M researchers studied pothole causes, repair materials, and practices to reduce pothole occurrence and increase repair durability. Find out the best pothole repair shape, the potential …
Water is one of the primary culprits behind pavement deterioration. Poor drainage systems or inadequate maintenance can allow water to accumulate beneath the road surface. This water weakens the base material, causing the pavement to sink, crack, and eventually form potholes. 4. Substandard Materials
Spot repairs are an effective way to deal with minor damage such as small cracks or potholes. Crack Filling. Cracks should be addressed promptly to prevent water infiltration, which can lead to more extensive damage. We recommend using a high-quality crack filler that is compatible with chip seal pavements. Pothole Repair
