The Ohio Department of Transportation has identified the need to specify durable, more permanent high performing pavement and bridge deck patching materials. These materials need to allow for expedited pavement and bridge deck wearing surface repair for worker and user safety. Currently, either temporary or generally specified in-kind or like materials are being used to perform pavement patching. Usually, the Department provides generically specified cementitious or cold mix asphalt materials for patching wearing surfaces with varied performance characteristics. Current products used for these repairs are generally those that have been used for many decades for which competition exists. However, new or proprietary products are difficult to specify unless incorporated into a construction project for research purposes, an approved equal is permitted, or procurement of the product complies with the Department’s direct purchasing requirements. Consequently, this creates a situation where the desired product is precluded from use.
The objective of this study was to specify durable, more permanent high performing pavement and bridge deck patching products that allow for expediting pavement and bridge deck wearing surface repair for worker and user safety. Aspects examined in this study include: history on causes of pavement patching failures, comparison of laboratory and field testing criteria from other organizations, product classifications based on material properties, analysis of available patching products, and identifying products to be tested based on previous research.
The products chosen for the winter patching project were FlexSet and MG Krete. They have been placed in the field already and were chosen due to their excellent low temperature range, compliance of most ODOT and ASTM 928 laboratory standards and great previous field testing results from ERDC and NTPEP. The other four products recommended for summer placement are Delpatch, RepCon 928, SR-2000 and Optimix. They displayed characteristics desirable for further testing and represent a range of material classifications.
Recommended laboratory standards were specified based on current ODOT requirements and past research and are listed in this thesis. Field recommendations consisted of having the product representative present on site during placement and to document all conditions of the patch hole, surrounding pavement and weather conditions.
