Abstract:
An experimental campaign was undertaken to assess the impact of deterioration and rehabilitation on the performance of corrugated steel horizontal ellipse culverts. A corrugated steel horizontal ellipse culvert was corroded using an accelerated corrosion technique and then buried up to a soil cover of 0.45 m. It was subsequently tested using simulated tandem axle loading. The culvert was then rehabilitated using the paved invert technique and tested under the same loading arrangement before being loaded up to its ultimate capacity. Results were compared with a previous study on an intact horiz

Abstract:
More than 47,000 culverts have been installed under the highways of Utah. The Utah Department of Transportation (DOT) maintains these culverts but has no comprehensive system for assessing condition and planning maintenance activities. Utah DOT initiated a study to determine the condition of its culverts by field surveys. The objective was to develop a system of qualitative and quantitative performance measures to assess both the long- and short-term behavior of highway culverts and to support the Utah DOT effort to modify and populate a computerized database designed to store culvert inspecti

Abstract:
The objective of this research was to determine the probability of road overtopping occurrence for a road culvert caused by surface runoff from the upstream catchment. A hydrological–hydraulic model was used for the development of an algorithm for road culvert maintenance based on the overtopping occurrence probability (CMOOP algorithm) for small mountain catchments. The hydrological model defines the regression dependence between the runoff hydrograph peak values and the probability of occurrences, whereas the hydraulic model calculates the culvert flow capacity by including in the calculatio

Abstract:
Transportation agencies are currently challenged to keep up with culvert infrastructure that is rapidly deteriorating due to lack of adequate maintenance and capital improvement. It is imperative for the transportation agencies to identify and rehabilitate deteriorated culverts prior to their failures. Among several concerns, lack of rational rehabilitation prioritization tools is foremost. Complicating this need further, current practices vary widely across the state departments of transportation (DOTs) which makes it difficult to develop a universal approach for prioritizing failing culverts

A cost-effectiveness analysis was used to study safety-treatment options for embankments and culverts on resurfacing, restoration, and rehabilitation (3R) projects. An examination of the need for cable and W-beam guardrails to shield traffic from roadside embankments and roadside culverts, respectively, was made. Average embankment and culvert accident severities were estimated using Highway Safety Information System data from Utah and Michigan. Average accident severities were calibrated through computer simulations of ran-off-road accidents. Simplified design charts were developed to allow h

A framework for inspection, rehabilitation, and replacement of corrugated steel culvert pipes (CSCP) is developed. It is expected to lead to developing a culvert information management system (CIMS), wherein justification and need are based on recent Governmental Accounting Standards Board (GASB) requirements. The CIMS will assist in evaluating infrastructure assets and facilitate comparing present costs of preserving infrastructure. Benefits include long-term savings from adopting optimized preventive maintenance strategies. CSCP condition states are used to express the extent of deterioratio

In July 1987, a section of the southwest wall of Sault Ste. Marie Lock failed during a locking operation when a portion of limestone facing, 60 m by 8 m, separated from the rubble backing wall. Engineering investigations resulted in the selection of the Recreational Lock Option, involving either downsizing the lock chamber within the existing lock or constructing a new lock as the most viable solutions. A Dry Dock Option, where the lock would be used to store craft during the winter months, was also considered. However, this option was abandoned during the course of testing. The engineering in

Abstract:
The trenchless rehabilitation of damaged rigid sewers has become a competitive alternative to conventional methods of pipeline replacement. However, buckling caused by fluid load is identified as the important limit state in the current pipe-liner design standard, while the contribution of the damaged rigid host pipe in the assessment of resistance to earth loads as well as disturbance to the liner (e.g., vehicle loads) is neglected. Fullscale testing in the laboratory is used to investigate the soil–host and pipe–liner interaction. Two host-pipe–liner systems are examined. The first system in

Baffles can be installed in culverts to mitigate upstream connectivity loss; however, evaluation of their effectiveness is limited.

Managing the rehabilitation of co-located infrastructure assets (pavements, pipelines, culverts, etc.) has become a major challenge for municipalities due to the varying rehabilitation requirements of these assets and the need for better coordination of rehabilitation works. Yet, most of the existing fund-allocation methods are not structured to address co-located infrastructure rehabilitation work in a systematic manner. This paper, therefore, extends the enhanced benefit-cost analysis (EBCA) optimization method that was developed earlier for a single asset type, to the case of co-located ass

Abstract:
Corrugated metal culverts have been used to convey surface drainage under local streets and major highways all over North America. Inverts of these culverts often deteriorate over time as they are constantly exposed to potentially harsh flow conditions. Invert concrete paving has been a traditional treatment used by roadway departments to rehabilitate metal culverts of which the bottoms are heavily rusted and beginning to perforate. The benefit of this rehabilitation method is clear from the hydraulic aspect but not from the structural aspect. A study was carried out recently for the Ohio Depa

Buried steel structures, commonly referred to as buried bridges, culverts, or soil-steel structures are a valuable bridge crossing solution. Owners manage their bridge assets by evaluating their condition and rehabilitating as required. Ontario’s resources for managing and rehabilitating buried steel bridge structures are limited, and an investigation into the maintenance and rehabilitation practice of Ontario’s assets demonstrates a lag in their maintenance and rehabilitation. Knowledge regarding rehabilitation of these structures is dispersed and unconcise, leaving owners challenged to under
