Preventive Maintenance for Recreational Trails Status: CompleteReport Date: 08/04/2009 Summary: Researchers evaluated the effectiveness of using pavement preventive maintenance techniques for recreational trails -- including various surface sealing and crack treatments -- by applying them to several trails in Minnesota and comparing their permeability and surface texture to untreated control sections. Results showed that all of the treatments reduced the permeability, and all fog seal treatments did so while consistently providing a high-quality surface for trail users.
