Abstract:

A study was conducted to determine the feasibility of utilizing high pressure waterjet cutting technology as an infrastructure maintenance tool. The influence of waterjet cutting parameters, compaction technique, repair methods, and environmental factors on the behavior of asphalt pavement materials have been systematically evaluated. Results indicate that the waterjet can be effectively used in repair operations for asphalt pavements. Also, the waterjet has a distinct advantage over other conventional mechanical cutting methods since it does not damage pavement materials immediately below and adjacent to a deteriorated region. Based on this study, a field portable prototype cutting unit has been designed.
