Development of a Compaction Quality Control Standard for the Small Diameter Pressuremeter

Quality control during soil compaction is critical to the proper construction of our roadways and structures. There has always been a void between laboratory moisture-density compaction and the soil’s strength and stiffness.

The TRB IDEA (Innovations Deserving Exploratory Analysis) Program's NCHRP IDEA Final Report for Project 244: Development of a Compaction Quality Control Standard for the Small Diameter Pressuremeter presents information on the development of a new product called the SSMini Pressuremeter that produces stiffness and strength in less than a minute and will soon be available at a initial cost of about $30,000 and with $1,000 annual calibration costs.
