  Rock Materials - NRCS Field Classification System
  

  Credits: 1 PDH

  PDH Course Description:

  The NRCS uses the Rock Material Field Classification (RMFC) system to classify rock and assess rock performance for a variety of engineering applications concerning rock formations. The system is designed for use by personnel trained in its use and knowledgeable of its limitations. It is particularly suited to describing rock material in support of NRCS engineering activities at the reconnaissance and preliminary (planning) levels.
  

  
  

  Classification (by any system) alone does not preclude or replace laboratory testing for specific engineering design purposes.

  Topics:

  • Rock material field classification system
  • History of RMFC system
  • The rock unit
  • Outcrop confidence level
  • Classification elements
  • Classification process
  • Evaluating earth material for excavation  
  • Ripping index method
