This program will provide an overview of Geosynthetic Reinforced Soil — Integrated Bridge System (GRS-IBS), a bridge design concept being promoted by the Federal Highway Administration to accelerate construction time and offer significant cost savings for the construction of local, county and state bridges. Segmental Retaining Wall (SRW) facing elements, along with geosynthetic reinforcement material, is proving to be a viable solution for a majority of the bridges known to be structurally deficient and in need of replacement across our nation. The presentation addresses the design concept, key materials, specifications and important construction details. A case study example illustrating the construction sequence is also provided.

Learning Objectives

Participants will:

    Learn the advantages and limitations of GRS-IBS and what makes these systems so cost effective compared to traditional methods.

    Be able to describe the key components that make up a GRS-IBS structural system.

    Understand the design process for a GRS-IBS system, and what is included in project drawings and specifications.
