Abstract

This study makes the performance evaluation of water-jet chipping through analysis of ruggedness of chipping surface. The ruggedness is mapped by 3D Laser Scanner and the results are also compared with the chipping surface by mechanical chipping. And the details of in-situ works is investigated for increasing interface adhesion between existing concrete and repairing mortar. Water-jet has good operation efficiency which is up $60m^2$ per hour when the chipping depth is 7cm and also has a large ruggedness about 1.65.
