Flexible Pavement Preservation Workshop (1.2 CEUs)
Venue: Calgary, AB
|Event Date/Time: Dec 15, 2011||End Date/Time: Dec 16, 2011|
Pavements preservation is a program employing a network level, long-term strategy that enhances pavement performance by using an integrated, cost-effective set of practices that extend pavement life, improves safety and meet motorist expectations (FHWA).
Pavement preservation includes routine maintenance, preventive maintenance, and minor rehabilitation. The key concept in a successful pavement preservation program is to apply the right treatment, to the right pavement, in a right time. Although this concept looks straightforward, its implementation is a complicated engineering question.
This course provides detailed information to assist pavement engineers in developing the most reliable and cost-effective maintenance and rehabilitation alternatives for existing flexible pavements. It addresses the problem of maintenance and rehabilitation in a logical sequence: existing pavement structure evaluation and condition assessment, distress mechanisms, assignment of feasible strategies and alternatives, selection of preferred alternatives. Example of a typical pavement preservation project including: data collection, field work, developing strategies and alternates, and life cycle cost analysis will be reviewed.
A background in pavement design is recommended.
The main objective of this course is to provide participants with a thorough understanding of important factors in flexible pavement maintenance and rehabilitation. The focus will be on best practices of pavement preservation used by Canadian highway agencies.
The course has been designed for pavement owners/users, consulting engineers, contractors and engineering technologists. A basic background of pavement engineering is required. This course is an excellent opportunity for those wishing to develop their knowledge on pavement preservation.
Upon completion of the workshop participant will be able to:
To recognize the main concept in pavement preservation: right time, right treatment, right time.
To learn methodologies in pavement evaluation for preservation; structural and functional evaluation
To identify flexible pavement distress types and their extents and severities
Become familiar with procedures for project field surveys, including coring, lab testing, and non-destructive deflection testing
To understand how to link pavement design considerations with the processes for pavement preservation
To learn important factors in the design and selection of various pavement preservation methods, routine maintenance, major maintenance, surface treatments, overlay, various recycling methods, and reconstruction
To learn Life Cycle Cost Analysis for comparing viable treatments
Long-term monitoring, research, and future trends in pavement preservation
