Caltrans: Pavement Marking Retroreflectivity

Caltrans PI: Pavement Marking Retroreflectivity
Client: California Department of Transportation - Division of Research, Innovation, and System Information (DRISI)
Audience: Caltrans managers and staff, partners, stakeholders, other state DOTs

CTC prepared this report for Caltrans to help the department gather information about other states’ practices for uses of retroreflectivity values in monitoring pavement markings, including warranty-based pavement marking programs. We conducted two surveys of other state DOTs as well as a literature review.
