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 and pore pressure measurement is also very important in transportation applications such as landslide warning systems, rainfall-induced slope failures, embankment settlement, and pavement performance monitoring. State departments of transportation (DOTs) are piloting new devices and methods that could be more effective, less expensive, and less time consuming than traditional devices and methods. 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. The synthesis will document practices ranging from pilot studies to established practice.
