2025 Drawing - Trimming of Bridge Embankments.pdf

This is a Kentucky Department of Highways standard drawing (RGX-100-05) detailing the treatment of embankments at end-bents. The drawing provides specifications for four distinct materials and their application in bridge construction: slope protection, embankment materials (granular, rock or soil), granular pile core/cohesive pile core, and structure granular backfill. The plan includes both a top-down view and cross-sectional view (Section A-A) showing the placement of these materials, along with 4" perforated underdrain pipes and 8" perforated underdrain pipes for headwall construction.

The drawing includes specific technical requirements: slope protection as required per bridge plans, granular/rock embankment as specified in roadway plans, granular pile core requirements for granular/rock embankment and cohesive pile core requirements for drilled shafts and pre-drilled piles, and mandatory structure granular backfill. The document references additional standard drawings RGX-105 and RDP-010 for complete specifications. The drawing illustrates an end-bent with a zero degree skew for simplicity, though the same principles would apply to varied structures.
