The objective of this course is to enable the students to learn the most reliable and cost-effective rehabilitation techniques for both flexible and rigid pavements. The course also provides students with the understanding of the process of pavement maintenance and rehabilitation techniques in logical sequence involving existing pavement structural evaluation, condition assessment, identification of distress mechanisms, life-cycle costs analysis and selection of feasible alternatives.
Introduction and definitions. Pavement condition surveys, materials, structural, and traffic data evaluations. Flexible pavement rehabilitation techniques: crack sealing, surface rehabilitation, hot mix asphalt overlays. Rigid pavement rehabilitation techniques: joint sealing, pressure relief joints, partial and full-depth repairs, slab stabilization and jacking, load transfer rehabilitation, rigid pavement overlay design. Identification of feasible alternatives. Selection of the preferred alternative.
At the end of the course, the students will demonstrate the ability to:
- distinguish between flexible pavements and rigid pavements, their structural layers and construction processes
- perform initial site surveys to gather necessary information for pavement condition evaluation and distress surveys and prepare charts and plots to summarize their survey results
- conduct detailed load associated distress surveys and identify their possible reasons and mechanisms for the observed distresses
- prepare rehabilitation and maintenance project plan to remedy deteriorated pavement sections
- propose a number of alternative rehabilitation and maintenance projects to recover the serviceability of existing pavement equivalent to that of new constructed pavement
- perform life cycle cost analyses of feasible alternatives and analyze them for their cost, maintainability, constructability and reliability throughout their service life
- determine the most feasible alternative and present evaluation and analysis results to support the reasons for the selected alternative plan.
