Porous Pavement Cleaning Machine

Porous Pavement Cleaning Machine is designed to clear the clogging of porous pavement using water jet followed by the suction of dirt water in order to prevent the pavement from decreasing in its function.
Since the clogging of porous pavement results in the decrease of noise reduction effect and drainage function, it is recommended that the cleaning operation be executed regularly. It is expected that the operation at an earlier stage of the clogging can bring about a better effect.
There are two types of cleaning operation for clogging removal; recovery and maintenance.
Recovery is done when porous pavement has a heavy clogging to show a significant functional decrease. The machine operates at a speed of about 1km per hour. Maintenance is done when the functional decrease is light. The machine operates at a speed of about 10km per hour.
