Investigation of Spall Repair Materials for Concrete Pavement: Summary Report
Spalling that occurs at transverse cracks or joints in portland cement concrete (PCC) pavement is a visible surface distress caused by pieces of delaminated concrete being dislodged under traffic and roughening the surface of the pavement. The effective repair of this distress type in a short period of time requires more 'exotic' materials to ensure that sufficient strength, bond, and stiffness are provided to restore the ride quality of the pavement surface. For many years, the Texas Department of Transportation (TxDOT) has been confronted with the repair of spalled concrete pavement in a short period of time to avoid traffic delays and has tried a number of different repair products with varying degrees of success. This project, 0-5110, focused on understanding which repair products work best under these conditions based on laboratory tests and field performance surveys. The project also developed guidelines to assist engineers in selecting cost-effective spall repair materials and procedures that work well for rapid repair.
