Method and apparatus for processing pavement surface

摘要

Cavitation is produced through injection of pressurized water from an injection outlet of an injection nozzle (17a) toward the pavement surface in liquid of a liquid storage part (T1) formed on the pavement surface. A clogging object in a cavity of a pavement is isolated by impactive force of the cavitation, and the isolated clogging object is removed by suction with water.
