2025 Drawing - Trimming of Bridge Embankments.pdf

This is a technical drawing from the Kentucky Department of Highways detailing the treatment of embankments at end-bents, designated as Standard Drawing No. RGX-100-05. The drawing provides specifications for four distinct material types used in bridge embankment construction: slope protection, embankment (granular, rock, or soil), granular pile core/cohesive pile core, and structure granular backfill. The plan includes both a plan view and cross-sectional view (Section A-A) showing the placement and configuration of these materials, along with 8" perforated underdrain pipes for headwall construction.

The drawing specifies several key requirements: slope protection is required as noted on bridge plans, granular or rock embankment is required per roadway plans, granular pile core is required with granular or rock embankment, and cohesive pile core is required with drilled shafts and pre-drilled piles. Structure granular backfill is required at all times. The drawing shows a zero-degree skew end-bent configuration, though the notes indicate these principles apply to varied structures. The document references current standard drawing RGX-105 for additional material limits definition and RDP-010 for headwall construction specifications.
