Pavement Coring
Project Development Pavement coring may be required to determine existing structural section information for surface obliteration, widening, etc.
Pavement coring may be required during construction to provide:
- Correlation of LTMD (Laboratory Test Maximum Density) and nuclear gauge "in place compaction" per CTM 375
- Density or specific gravity tests per CTM 308 and or 309
If coring is required, provide the following information:
- Route, postmile, EA.
- Type of material to be cored:
- Asphalt
- PCC
- Underlying Aggregate base/ Aggregate sub base layers
- Diameter and depth of core. Maximum core width and depth is 8 inches (200 mm) and 5 feet (1525 mm). The Geotechnical Branch must be contacted for any depth greater than 5 feet.
Contact (707) 445-6355 for more information and availability.
