NRRA: Continuous Moisture Measurement During Pavement Foundation Construction

Status:  Active
Project Start Date:  02/26/2021


Accurate and timely moisture measurement of earthwork during compaction of foundation layers is crucial to proper construction and long-term durability of the pavement structures. The objective of this study is to demonstrate a prototype/breadboard of a device that can continuously measure moisture during pavement foundation construction. This project will document the current state of knowledge concerning field moisture measurement during pavement foundation construction, and case studies that demonstrate cost savings resulting from more effective moisture measurement. This project will also provide critical information regarding the most effective moisture measurement devices suitable for improving compaction near structures such as retaining walls and bridge abutments. Finally, a prototype device capable of continuously measuring moisture during pavement foundation construction will be tested and demonstrated.
