Geosynthetic Reinforced Soil Integrated Bridge System Interim Implementation Guide

APPENDIX D. TYPICAL GRS–IBS WORKING DRAWINGS

D.1 SINGLE–PAGE PLAN SHEET

Illustration showing a typical geosynthetic reinforced soil integrated bridge system (GRS-IBS) on a single-sheet plan. Included on the single-sheet plan are three main figures: a cross section of the GRS-IBS, a cross section of the wing walls, and the concrete masonry unit (CMU) block schedule of the abutment face and wing walls. All the principal elements of the GRS-IBS (the reinforced soil foundation (RSF), the abutment, and the integrated approach) are shown on the cross section of the GRS-IBS. Within the GRS abutment, the reinforcement schedule and the bearing reinforcement bed are depicted. There is also a close-up view to show details of the clear space and setback. The reinforcement schedule of the wing wall is shown on the cross section of the wing wall. The bridge loads and bearing area are written in the top left corner.

D.2 ESTIMATED QUANTITIES AND GENERAL NOTES

Illustration showing general notes about the design of the geosynthetic reinforced soil (GRS) abutment as outlined in the manual. Included is a table of the GRS quantities showing the amount of fabric, quantity of aggregate, and amount of concrete masonry unit (CMU) facing block needed. The sheet also shows the estimated quantities for the superstructure and the asphalt pavement and other materials associated with the integration of the superstructure and roadway.

D.3 PROJECT PLAN AND PROFILE

Illustration showing two parts: an aerial photo of the bridge project site and the cross section profile of the roadway leading to the bridge.

D.4 GRS ABUTMENT DETAILS

Illustration showing a single-sheet plan. This drawing is very similar to what is shown in figure 100; however, included in this figure are the pay limits of the cut slope. The bearing pressure for both live (HL-93 with impact) and dead load is also shown in the top right corner.

D.5 SITE PLAN

Illustration showing the site plan for a bridge project. The site plan is divided into two parts: the top part shows a topographic map view of the roadway elevation with the bridge superimposed, and the bottom part shows a cross-sectional sketch of the roadway and the bridge in relation to the elevations.
