Chip seals are a cost-effective and often-used strategy for maintaining and preserving pavements.
To ensure that the chip seal treatments applied on the state’s highways perform well and last a long time, the Oregon Department of Transportation initiated a research study to identify tests that can be performed during the application process. The project’s findings will help the agency enhance its chip seal procedures and maximize its maintenance investments.
