Culvert and Storm Drain Inspection Seminar
Thursday, September 1, 12:30 – 5:00 PM
Culvert washouts and failures have a significant impact on railway viability, often on par with the consequences of bridge failures. Culvert and storm drain systems are vital assets that require periodic maintenance and repair to achieve their design service life and proper function. This course presents a methodology for rapid condition evaluation of culverts and buried bridges that establishes a rating system to prevent failure/washout. The system also provides a framework for managing assets, reducing risk, and prioritizing maintenance and rehabilitation.
The AASHTO Guide for Inspection of Culvert and Storm Drain Systems
replaces the 1986 FHWA Culvert Inspection Manual
referenced in the AREMA Manual for Railway Engineering as the recommended publication for developing a culvert and storm drain inspection program. The new guide reflects industry changes such as new pipe types, culvert design for alternate uses, evaluation of storm drain systems, and advanced inspection techniques. This educational workshop introduces the contents of the guide and provides training on the use and implementation of the component rating system.
The objective of this workshop is to provide inspectors and interested parties with quantitative and repeatable condition asset criteria based on inspection methods of the AASHTO Guide for Inspection of Culvert and Storm Drain Systems
. Learning objectives include the following:
- Understand the use and basis of the AASHTO Guide for Inspection of Culvert and Storm Drain Systems.
- Understand the rating system used in the Guide and introduce the underlying engineering principles and existing best practices.
- Enable culvert and storm drain inspectors to:
- Select an appropriate entry type,
- Identify distress for culvert or storm drain system components,
- Rate the condition of the system components (includes the approach, embankment, channel, end treatments, foundations, joints/seams, and barrel materials such as plastic, concrete, corrugated metal, masonry, and timber),
- Document findings of an inspection,
- Recommend corrective actions where appropriate.
- Identify areas of structural concern, hydraulic performance, and roadside compatibility, and
- Identify minor issues that can be addressed through maintenance before they become safety hazards.
Information presented in this workshop will enable agencies to make more efficient use of their culvert and storm drain assets by:
- Mitigating repair costs,
- Reducing risk of failure,
- Providing input to prioritize rehabilitation and maintenance,
- Developing a database of condition-based input for short- and long-term planning and budgeting for repairs and rehabilitation.
