John Poullain, P.E.
Course Outline
This two-hour online course discusses the procedures for partial-depth concrete pavement repairs (PDR) used to maintain and preserve concrete pavements. The FHWA text can serve as a reference and ranges from general instructions to specific practices for the procedures. Topics discussed are the selection and use of cements, polymer cements, bonding agents, dowels, construction processes, partial-depth repair limitations, pavement distress types, checklists, and troubleshooting guides. Photographs and drawings illustrate the types of pavement distresses and treatment.
This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
Learning Objective
At the conclusion of this course, the student will have covered these topics:
- PDR procedure used to maintain and preserve concrete pavements;
- Effectiveness and limitations of partial-depth concrete repair;
- When not to use PDR and full-depth repairs instead;
- Construction equipment used;
- Pavement distress types and causes;
- Concrete removal methods;
- Placing repair materials;
- Locating the repair boundaries and determine the extent of deterioration;
- Checklists and troubleshooting guides for PDR; and
- Drawings and photos illustrating the construction, materials and equipment used.
Intended Audience
This course should benefit civil engineers, pavement engineers, transportation engineers, field and office personnel, supervisors and maintenance personnel.
Benefit to Attendees
The student will become familiar with the procedures for partial-depth concrete pavement repairs (PDR) used to maintain and preserve concrete pavements.
Course Introduction
Pavement preservation has become more important for maintaining the national highways. FHWA and its partnership with states and other agencies have realized the benefits of preservation systems which equate to better pavement performance, safety and increased pavement life. The goal is to address pavement problems before more serious damage occurs. FHWA guidelines were developed for PDR as one technique to effectively restore slab integrity and rideability in order to extend the pavement service life. PDR is limited to removing deteriorated concrete from the top one-third of the slab.
The course text discusses the methods, pavement distresses, design considerations, construction processes and equipment used, project checklists and troubleshooting guides. Factors influencing performance including climate, traffic loading, and maintenance and construction activities are considered.
Course Content
The course is based on the FHWA publication “Partial-Depth Concrete Pavement Repair”, (2008 Edition, 13 pages), PDF file. Also used is the FHWA Checklist Series “Partial-Depth Repair of Portland Cement Concrete Pavements”, (2005 edition, 16 pages), PDF file.
