In this course, presented in Spanish, you will find a comprehensive guide for performing partial-depth repairs from planning, 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. The technique is an important preservation technique to 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 will cover all of the considerations, including patch materials and construction techniques to produce patches that are cost-effective and can last 10 to 15 years or longer.
Specifically, you'll learn how to employ successful practices and techniques on concrete pavement preservation projects. The following questions are answered in this course:
Why is the technique an important part of concrete pavement preservation?
What options are available for performing the construction processes and procedures?
Which options provide the best opportunities for success?
What materials are involved in the techniques?
What are the proper techniques for mixing, placing, and curing?
What are the specific, sequential tasks required to properly perform each of the techniques?
This course provides support and instruction for individuals involved in construction projects using concrete pavement preservation techniques. This training is ideal for construction foreman, workers, and technicians; agency inspectors and 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.┐
