• Description:
  The project focused on two main objectives: • Determining if a filter is necessary between the riprap layer and the underlying soil and then recommending design and installation guidelines for riprap filters (granular and geosynthetic). • Examining issues related to placing riprap on an abutment or riverbank slope and the associated stability of the slope and riprap. Researchers first conducted an extensive literature review. Next, a survey was sent to all state departments of transportation, contractors, and associated entities to establish the current state of the practice. The researchers then performed laboratory testing. They finally collected riprap failure case histories and analyzed them to reach recommendations
