There is a growing need to develop pavement preservation techniques for thinner concrete pavements. Many city and county concrete roads were constructed as far back as the 1960s, with a design life of 30 years. Now that they are well beyond their design life, cities and counties are seeking economical solutions to keep them in service.
There exists common repair techniques for restoring the servicability of concrete pavements, however most of these techniques have been developed for thicker, highway type pavements.
This project would process and analyze data from thin concrete test cells at the MnROAD facility that will undergo pavement preservation techniques such as retrofit dowel bars or plates and diamond grinding of the surface. From the analysis, design specifications and recommendations could be developed that would allow agencies to further extend the life of their existing thin concrete pavements.
