  • Abstract:
    This research project strives to help the Iowa Department of Transportation (DOT) fully achieve the full benefits of pavement

    preservation through training on proper selection, design, and application of pavement preservation treatments. In some cases, there is a

    lack of training when conducting one of these steps and the objective of applying pavement preservation techniques is compromised.

    Extensive amounts of literature on pavement preservation exist, but a structured approach on how to train staff in selecting, designing,

    and applying pavement preservation techniques is lacking. The objective of this project was to develop a training-oriented learning

    management system to address pavement preservation treatments (chip seals, fog seals, slurry systems, and crack seals and fills) as they

    are dealt with during the phases of selection, design, and construction.

    Early in the project, it was critical to identify the staff divisions to be trained and the treatments to be included. Through several

    meetings with the Iowa DOT, three staff divisions were identified: maintenance staff (in charge of selection), design staff, and

    construction staff. In addition, the treatments listed above were identified as the focus of the study due to their common use.

    Through needs analysis questionnaires and meetings, the knowledge gap and training needs of the agency were identified. The training

    modules developed target the gap from the results of the needs analysis. The concepting (selection) training focuses on providing the

    tools necessary to help make proper treatment selection. The design training focuses on providing the information necessary on the

    treatment materials (mostly binders and aggregates) and how to make proper material selection. Finally, the construction training

    focuses on providing equipment calibration procedures, inspection responsibilities, and images of poor and best practices.

    The research showed that it is important to train each division staff (maintenance, design, and construction) separately, as each staff

    division has its own needs and interests. It was also preferred that each treatment was covered on an individual basis. As a result of the

    research, it is recommended to evaluate the performance of pavement preservation treatments pre- and post-training continuously to

    compare results and verify the effectiveness of the learning management system.
