CT 106-June 2012 Changes

Caltrans has released a new version of CT 106: Definitions of Terms Relating to Specific Gravity.  The changes are minimal and are as follows:

  • Changed the definition of Specific Gravity from a ratio of mass to a ratio of weight.
  • Changed the reference materials for "absolute specific gravity" from ASTM E12 and AASHTO M132 to ASTM E1547 and AASHTO T84
  • For each specific gravity term mentioned, it now notes what California Test Method(s) you will see it in.
The June 2012 version can be found on the Caltrans website and here.  Happy Reading!
