About the research

Research objective:

This project will continue to perform in situ tests and visual surveys, and collect weather/temperature data over the 2016-2017 freeze-thaw cycle, on a two-mile stretch of Vail Avenue in Hamilton County, Iowa. These data and tests will further quantify the performance of the 20 demonstration sections on Vail Avenue to reassess the relative performance of the different stabilization methods, enabling more accurate long-term predictions of performance and maintenance costs.

The long-term benefits of the project will be to improve the quality, longevity, and state of good repair of Iowa roadways, which constitute a vital component of Iowa’s infrastructure. The field monitoring data will produce a better understanding of the longer-term performance, costs, and benefits of several stabilized demonstration sections of granular-surfaced road. As a result, county engineers will have improved information to help them decide on stabilization methods to help prevent and minimize damage due to frost boils and moisture-related damage on unbound granular roads.
