Grs-ibs design manual






















IBS - A fast, cost-effective method of bridge support that blends the roadway into the superstructure using GRS technology. This creates a simple, joint-less interface between the bridge and the roadway alleviating the "bump at the bridge" problem caused by uneven settlement between the bridge and the approaching roadway. The GRS-IBS system reduces costs by up to 60 percent. The easily modified design can be adapted to a variety of field conditions. Built in weeks instead of months, it can help state and local agencies meet the demand for small, single-span bridges by delivering low-cost, durable and low-maintenance structures in less construction time. GEOTECHNICAL ENGINEERING MANUAL: GUIDELINES FOR DESIGN AND CONSTRUCTION OF GEOSYNTHETIC REINFORCED SOIL INTEGRATED BRIDGE SYSTEM (GRS-IBS) GEM Revision #1 STATE OF NEW YORK DEPARTMENT OF TRANSPORTATION GEOTECHNICAL ENGINEERING BUREAU AUGUST EB Page 2 of 13 TABLE OF CONTENTS www.doorway.ru Size: 1MB.


This manual presents step-by-step guidance on the design of GRS-IBS using the Load and Resistance Factor Design methodology. Material specifications for standard GRS-IBS are also provided. Detailed construction guidance is presented along with methods for the inspection, performance monitoring, maintenance, and repair of GRS-IBS. FHWA has published a GRS-IBS Interim Implementation guide that can be used by state and local agency engineers for the design and construction of GRS-IBS. Engineers list 10 advantages from GRS-IBS installations County transportation engineers who have used GRS-IBS have reported what they view as the system's most important advantages. Geosynthetic Reinforced Soil-Integrated Bridge Systems (GRS-IBS) offers unique advantages, particularly in the construction of small bridges. Construction costs are typically 25 to 60 percent lower than conventional construction www.doorway.ru - An engineered fill of closely spaced alternating layers of compacted granular fill material and fabric sheets of geosynthetic.


This manual was developed to serve as the first in a two-part series aimed at providing engineers with the necessary background knowledge of GRS technology and its fundamental characteristics as an alternative to other construction methods. The manual presents step-by-step guidance on the design of GRS-IBS. Analytical. The first document is a manual covering the design and construction of GRS-IBS. This two-part document series designs GRS as a composite material with known and predictable performance and deformations. GRS - An engineered fill of closely spaced alternating layers of compacted granular fill material and fabric sheets of geosynthetic reinforcement. IBS - A fast, cost-effective method of bridge support that blends the roadway into the superstructure using GRS technology. This creates a simple, joint-less interface between the bridge and the roadway alleviating the "bump at the bridge" problem caused by uneven settlement between the bridge and the approaching roadway.
