The North Carolina Department of Transportation utilized Stalite Lightweight Aggregate for skin patching and crack sealing applications in North Wilkesboro, North Carolina. Surface cracking in asphalt can lead to significant structural deterioration if moisture infiltrates the pavement, making timely sealing essential.

Using lightweight aggregate in bituminous surface treatments provides a durable solution that bonds strongly with asphalt emulsion while minimizing loose aggregate. The lightweight properties help reduce the risk of vehicle damage from stray particles, making it well suited for high traffic roadways such as NC Highway 421, which carries approximately 14,000 vehicles per day.
