An object describing an in-situ California bearing ratio test procedure. The California bearing ratio (CBR) is a penetration test for evaluationof the mechanical strength of road subgrades and basecourses. The test is performedby measuring the pressure required to penetrate a soil sample with a plunger ofstandard area. The measured pressure is then divided by the pressure required toachieve an equal penetration on a standard crushed rock material.
Database handle for the object. It is of XML type ID, so is constrained to beunique in the XML document within which it occurs. An external identifier for the object inthe form of a URI may be constructed using standard XML and XPointer methods. This is doneby concatenating the URI for the document, a fragment separator, and the value of the idattribute.
