Abstract
Content

The normal road construction process involves subgrade (the existing soil) preparation followed by placement of an aggregate layer, and then the pavement surface layer (asphalt or concrete). In practice, most highways are designed using a set of assumptions that is sufficiently conservative to ensure that the roadway will meet its minimum specifications over its design life. The cost of the pavement layer can be optimized by testing the firmness of the prepared roadbed before paving. The testing process validates the basic design assumptions, and enables the amount of pavement to be tailored or optimized for each segment of the road. Ingios Geotechnics (Northfield, MN) was formed to develop and manufacture equipment to automate the process.
