Street sweeping, vacuum cleaning, high-pressure washing and milling |
All the methods brought improvements to the permeability rates. The high-pressure wash showed significant permeability recovery and appeared to be more efficient than street sweeping and vacuum cleaning. However, milling was the technique that showed the greatest efficiency in permeability recovery, although it is the most expensive |

High-pressure washing |
An improvement of about 35% in infiltration capacity was achieved on a severely clogged pavement |

Surface cleaning (with a broom), air cleaning (with a compressor) and high-pressure washing |
Regenerative air cleaning can efficiently remove sand sediments, while high-pressure washing can be more efficient for fine sediments such as clay. Surface cleaning with a broom did not shows any permeability improvement in any case |

Sweeping with a stiff household broom to agitate the debris in the voids, and after rinsing the surface with a garden hose |
It was effective to improve the permeability |

Regenerative air street sweeper, vacuum truck with a flexible 200 mm hose and a vacuum street sweeper (common municipal utility vehicles for cleaning pavements) |
The three cleaning methods were equally able to remove clogging materials that were located within 3.18 mm of the surface |

Pressure washing, vacuuming and power blowing, to restoring pervious concrete permeability |
Vacuuming and pressure washing are equally effective to improve the infiltration rate of the pavement clogged. Power blowing provides no improvement on infiltration rate, if it follows pressure washing |
