Highway Investigation Example

Integrated pavement, subgrade, sampling, CBR, and dry-density data for roadway design

A complete 30 m roadway boring for the Highway 7 Widening and Rehabilitation project, integrating asphalt, granular base and subbase, embankment fill, native subgrade, twenty split-spoon samples, SPT N-values, recovery, groundwater, water content, Atterberg Limits, CBR, dry density, and competent glacial till.
