This course provides a comprehensive guide for performing partial-depth repairs--from planning for, preparing, and evaluating the patch through testing and quality assurance after construction is complete. Partial-depth repairs are defined as the removal and replacement of small areas of deteriorated (or spalled) concrete pavement. Partial-depth repairs are an alternative to full-depth repairs in areas where slab deterioration is located primarily in the upper one-third to upper one-half of the slab and the existing load transfer devices (if any) are still functional.
This important preservation technique can slow or eliminate the spread of spalling distresses that tend to occur under repeated thermal stresses, freezing and thawing, and traffic loading. The information in this course covers all of the considerations for partial-depth repairs including patch materials and construction techniques to produce patches that are cost-effective and can last 10 to 15 years or longer.
You will discover detailed, how-to instruction that covers the full scope of tasks involved in successfully completing a full-depth repair project. The instructional methods in this Web-based training include short, focused, and task-based lessons, visual aids, and assignments that are directly applicable to work in the field.
This course provides support and instruction for individuals involved in construction projects using concrete pavement preservation techniques. This training is ideal for construction foremen, workers, technicians, agency inspectors, construction managers, and engineers.

There are no formal prerequisites for this course. The level of instruction assumes the participant has some awareness and involvement with paving processes, but the training is appropriate for participants regardless of past experiences with the techniques. Some instruction on how each technique fits into the broader context of pavement preservation is necessary in order to emphasize why a worker should follow best practices; however, most training content is focused on the how-to.
