Rock Material Field Classification System

COURSE NO: G01-005
COURSE PROVIDER: Jeelan Moghraby, Ph.D.
Rock Material Field Classification System
Course Highlights

This online engineering PDH course provides a basic understanding on how to classify rock materials using the Rock Material Field Classification (RFMC) system.


The RMFC system is used by the NRCS to classify rock and assess rock performance for several engineering applications. This system is vital in helping engineers understand the behavior and properties of the rock materials, and can be used alongside laboratory testing for specific engineering designs. Using this knowledge, engineers can make informed decisions and implement appropriate design and construction strategies tailored to the specific rock materials, ensure the success and safety of their projects.


This 1 PDH online course is applicable to geotechnical and civil engineers, as well as other professionals interested in learning how the RMFC system is used to classify and assess different rock types in the field.
Learning Objectives

This PE continuing education course is intended to provide you with the following specific knowledge and skills:

  • Understanding the importance of the RFMC system in engineering and construction projects
  • Knowing the classification elements of the RMFC system, and the process of using this system
  • Understanding the relationship between rock material properties and the engineering performance objectives
  • Learning how the Ripping Index is used to evaluate earth materials for excavation
