A seismic improvement works were completed on Market Road Underpass (MRU) in Auckland. The bridge consists of three structures: The Underpass, the Motorway Off-ramp and the Rail Overbridge. In the NZTA’s "Seismic Screening" of all state highway bridges MRU ...

<p>A geosynthetic-reinforced soil (GRS) mass is formed by placing closely-spaced layers of polymeric geosynthetic reinforcement in a soil mass during soil placement. The reinforcement in a GRS mass serves primarily to improve engineering properties of soil. ...

This manual outlines the state-of-the-art and recommended practice for designing and constructing Geosynthetic Reinforced Soil (GRS) technology for the application of the Integrated Bridge System (IBS). The procedures presented in this manual are based on ...

On 22 February 2011 the Mw6.2 Christchurch earthquake occurred with an epicentre less than 10 km from the Christchurch Central Business District (CBD) on an unknown buried fault at the edge of the city. The majority of damage was a result of lateral spreading ...

Bridge approaches provide a smooth and safe transition of vehicles from highway pavements to bridge structures and vice versa. Settlement at the end of the bridge and highway pavements also known as a ‘bump’ in the roadway, causes not only inconvenience to ...

Bridge approaches provide smooth and safe transition of vehicles from highway pavements to bridge structures. However, settlement of the bridge approach slab relative to bridge decks usually creates a bump in the roadway. The bump causes inconvenience to passengers ...

Surtees Bridge, which carries the A66(T) over the River Tees near Thornaby-on-Tees in the UK, has been showing signs of distress that predate its opening in 1981. Subsequent investigations have shown that the bridge distress is related to unexpectedly large ...

The purpose of this study is to document the performance and effectiveness of two mitigation techniques, geosynthetic reinforced fill and flowable fill, installed behind four Wisconsin bridges. Two of the bridges (Hemlock and Cranberry bridges) are founded ...

<p>This Reference Manual is intended principally to serve as a supplement to the Participant&rsquo;s Workbook for the FHWA&rsquo;s National Highway Institute Course on Load and Resistance Factor Design for Highway Bridge Substructures. The Reference Manual ...

<p>The seismic performance of bridge structures and appurtenant components (i.e., approach spans, abutments and foundations) has been well documented following recent earthquakes worldwide. This experience demonstrates that<br />bridges are highly vulnerable ...
