Synthesis of Information Related to Highway Practices. Topic 53-18. Moisture Measurement for Foundations and Slopes

Accurate and timely moisture measurement of soils, aggregates, and recycled materials is critical to properly compact these geomaterials. In addition, moisture measurement is also very important in transportation applications such as landslide warning systems, rainfall-induced slope failures, embankment settlement, and pavement performance monitoring. New devices and sensors are available that could replace traditional methods that are more expensive and time-consuming. The objective of this synthesis is to document current state DOT practices for field and laboratory moisture measurement for foundations and slopes for pavements and structures. Information to be gathered includes (but is not limited to): laboratory and field testing equipment used by state DOTs (e.g., devices, instruments, systems); techniques by state DOTs for moisture measurement; and spatial and seasonal variation of moisture measurements. Information will be gathered through a literature review, a survey of state DOTs, and follow-up interviews with selected agencies for the development of case examples. Information gaps and suggestions for research to address those gaps will be identified.
