Chip seals are one of the most common treatments for extending the service life of asphalt pavements. To ensure its chip seals are achieving the intended results, the Virginia Department of Transportation (VDOT) conducted an assessment of eight pavement resurfacing projects across the state.
The research evaluated the agency’s practices and monitored the test pavements for multiple seasons to evaluate performance in the field. The project resulted in material and design recommendations to achieve better and more cost-effective results.
