The objective of this study was to assess the skid resistance performance of pavements in Oklahoma following preventive maintenance treatments. The assessment method employed herein was based on physical aggregate properties and economics in an optimal manner. Several state-of-the-art laboratory and field instruments were used to collect data on aggregate morphology, and 3D surface texture and skid resistance of pavements. The impacts of aggregate characteristics on the skid resistance of pavements were also investigated and used in developing deterioration models and life cycle cost analysis.
