Real-Time Measurement of Soil Stiffness During Static Compaction

Is continuous sensing of soil properties during static pad foot roller compaction achievable? A new pad-based, roller-integrated system for real-time measurement of the elastic modulus of fine- and mixed-grain soils is the goal of “Development of Soil Stiffness Measuring Device for Pad Foot Roller Compactor,” a project of the Federal Highway Administration’s (FHWA’s) Exploratory Advanced Research (EAR) Program. Initiated in 2008, the study is being conducted by the Colorado School of Mines with the participation of roller manufacturers and the Colorado and Minnesota Departments of Transportation.
