Table summary is a generalization of subsurface conditions at the individual soil boring locations only. They may not <br />reflect variations in subsurface strata occurring on site between boring locations. The general geologic origin of <br />retained soil samples is listed on the boring logs. <br />2. Measured thickness of the pavement core. <br />3. Apparent aggregate base thickness, at time of our fieldwork, by visual inspection only. The classification is not meant <br />to confer conformance with DOT specifications. <br />4. Undocumented fill soils. <br />5. Pavement core thickness may not be representative due to crumbling during coring process. <br />Page 4 of 10 <br />
