The training course is presented in 9 blocks, each containing subdivisions referred to as modules. Block 1, Course Introduction, introduces the participant to this training course and to the 4R (restoration, recycling, resurfacing, reconstruction) program. This block contains three modules consisting of the background information of interest to the participant. Block 2, Project Survey and Evaluation, provides training in the collection and evaluation of the information necessary to design and construct a 4R project. Block 3, Restoration, contains many different methods of repair of both concrete and asphalt pavements. Although many of these methods have been performed in various ways by maintenance crews, the same procedures need careful reconsideration when applied to large 4R projects by contractors. Block 4, Recycling, will familiarize the participant with recycling alternatives for both rigid and flexible pavements. Block 5, Resurfacing, will familiarize the participant with the use of findings from the pavement surveys and evaluation in the overlay design process, criteria for minimum overlay thickness and procedures for thickness design for structural overlays, methods used to retard reflective cracking, and selection of the overlay type best suited for a particular situation. Block 6, Other Considerations for 4R Projects, acquaints the participant with other factors such as available right-of-way, available funds, environmental considerations, safety, geometric design of the existing facility, and traffic through the construction zone. Block 7, Selection of the Preferred 4R Alternative, provides further instruction in the development and evaluation of 4R design alternatives for a given project, and the selection of the "preferred" alternative. Block 8, Workshop on 4R Project Design, provides the participant with practical workshop examples of the development of a 4R project. Block 9, Summary and Student Evaluation of 4R Training Course, provides a summary of the material presented in the eight previous blocks, and gives the participant an opportunity to evaluate the course and the instructors.
