Partial-Depth Concrete Pavement Repair

John Huang, Ph.D., PE and John Poullain, PE

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.

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 ride ability in order to extend the pavement service life. PDR is limited to removing deteriorated concrete from the top one-third of the slab.

This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
