abstract
Spalling of concrete pavements has been commonplace in pavements. In Texas a common failure mode consists of shallow spalls in the transverse directions that occur along transverse cracks. Many repair materials have been used with varying success. A research study was conducted by The University of Texas at Austin and Texas A&M University to characterize the properties of the repair materials. Field observations were made of some of these materials that had been in place for several years, and a field trial was conducted on a busy interstate highway. The best performing materials were those that had very low moduli of elasticity, even though the coefficients of thermal expansion were high. The product of coefficient of thermal expansion and modulus of elasticity equal or less than 125 kPa/C was the best predictor of success for the materials tested. 2009 Taylor & Francis Group.
