Non-Cementitious Repair Materials Study

As Wisconsin’s concrete pavements age and deteriorate, the Wisconsin Department of Transportation (WisDOT), as well as local agencies, continually search for technologies and methods of repair that not only correct the defects but preserve the roadway condition and consequently extend the serviceable life of, those pavements. This search has broadened as of recent as traffic demands on the State’s high order facilities necessitate the repairs be completed with minimal travel restrictions; routinely requiring lane closures be limited to off-peak travel times (typically 6 to 8 hours in duration at night). This short closure/construction window drastically limits the conventional repair methods available to the agencies. The conventional preservation repair methods for concrete pavements would be partial or full depth repairs that are cast in-place using conventional concrete mixtures. This requires concrete cure times that would not be permissible under the closure restrictions. To fit the limited closure times, concrete pavements repairs have been limited to those that utilize asphalt or rapid setting concrete materials. Neither method has shown to provide consistently reliable and durable preservation repairs. In an effort to identify alternative repair methods, WisDOT has utilized non-cementitious concrete repair materials on facilities around the state. These non-cementitious repairs have experienced varying levels of success. In the repairs that have experienced failure, the failure is generally not attributed to the repair material or workmanship. Rather the failures appear to be the result of misapplication of the non-cementitious product. In several instances, the repairs failed due to the continued deterioration and poor condition of the concrete around it. Suggesting the non-cementitious products were applied in order to address traffic management concerns, rather than the pavement distress. The goal of the study is to make recommendations regarding the proper selection and application of non-cementitious concrete repair materials. The objectives of this project are to: (1) Evaluate availability and applicability of non-cementitious repair materials and products. (2) Evaluate the processes used to identify the application of currently installed non-cementitious repairs. (3) Evaluate the performance of the currently installed non-cementitious repairs. (4) Develop protocols to identify application locations of non-cementitious repair materials and methods. (5) Make recommendations to WisDOT specifications and manuals. Including, but not limited to: the Facilities Development Manual (FDM), the Concrete Pavement Rehabilitation Manual (FDM Chapter 14, Exhibit 10.1), and Construction and Materials Manual.
