ABSTRACT
Abstract The paper presents the preliminary findings of a project aimed at determining the long term performance of sprayed repair in highway structures. Different generic materials were used to repair deteriorating bridge structures using the dry spray process. The performance of these repairs was monitored to gain an understanding of the structural interaction between the spray applied repair material and the concrete substrate. The results show that the elastic modulus (of both the repair material and substrate) is the property which has the greatest effect on the performance of the repair. Keywords: Bridge repair, material properties, performance, redistribution of stress, repair materials, sprayed concrete.
