2025 Drawing - Trimming of Bridge Embankments.pdf

This is a technical drawing from the Kentucky Department of Highways titled "Treatment of Embankments at End-Bents" (Standard Drawing No. RGX-100-05), which details the construction specifications for bridge embankments. The drawing provides detailed plan and cross-sectional views showing the required components and materials for end-bent embankment construction, including slope protection, granular embankment, granular pile core, structure granular backfill, and 8" perforated underdrain pipes.

The drawing specifies four distinct material zones with different requirements: slope protection (as noted on bridge plans), embankment material (granular, rock, or soil per plans), granular pile core or cohesive pile core (required with drilled shafts and pre-drilled piles), and structure granular backfill (required at all times). The document notes that while a zero-degree skew is shown in the drawing, the same principles apply to varied structures. The drawing references current standard drawing RGX-105 for defining material limits and RDP-010 for headwall construction specifications.
