Non-destructive roller-integrated acoustic wave detection technique for continuous subgrade soil compaction evaluation, SPR-4833

The Indiana Department of Transportation (INDOT) received a $213,453.26 Formula Grant award from the Department of Transportation Federal Highway Administration under the Highway Planning and Construction program (CFDA 20.205) on August 10, 2023. The grant will fund the development and implementation of a "Non-Destructive Roller-Integrated Acoustic Wave Detection Technique for Continuous Subgrade Soil Compaction Evaluation" project, identified as SPR-4833. This project aims to create a non-destructive method for real-time monitoring and evaluation of soil compaction during highway construction and maintenance activities. The funding will support the research, testing, and deployment of this innovative acoustic wave-based technology to enhance the efficiency and quality control of subgrade soil compaction processes within Indiana's transportation infrastructure projects.
