    DEVELOPMENT OF AGGREGATE CHARACTERISTICS-BASED PREVENTIVE MAINTENANCE TREATMENTS USING 3D LASER IMAGING AND AGGREGATE IMAGING TECHNOLOGY FOR OPTIMIZED SKID RESISTANCE OF PAVEMENTS (FHWA-18-05)

    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.

    LONG TERM PAVEMENT PERFORMANCE MONITORING OF SIX LTPP SPS-10 SECTIONS IN OKLAHOMA WITH 3D LASER IMAGING (FHWA-OK-19-05 2115)
    (2019-12) Wang, Kelvin; Li, Joshua Q; Yang, Gary Guangwei; Oklahoma Department of Transportation. Materials and Research Division. Office of Research & Implementation
    Under the LTPP Specific Pavement Study 10 (SPS-10) experiment initiative, the Oklahoma Department of Transportation (ODOT) constructed five warm mix asphalt (WMA) testing sections and one hot mix asphalt (HMA) control section. In this project several art-of-the-state instruments were used to collect a comprehensive array of pavement surface characteristics data. The data collection was performed biannually for five years for long term field performance evaluation. It is demonstrated that four of the five WMA sites exhibit comparable performance as compared to that of the HMA section, in terms of pavement cracking, rutting,and roughness. In addition, aggregate properties and mixture design show impacts on pavement macrotexture and skid resistance properties.
