Zusammenfassung: | The invention relates to a method of water permeability recovery by surface planing and milling regeneration of a blocked permeable concrete pavement. The method is characterized in that a regeneration basic procedure method is surface planing and milling-working face cleaning- adhesive spraying-surface regeneration, namely the surface of the blocked water permeable concrete pavement is mechanically planed and milled for 2-4 cm; coarse clastic particles on the planing and milling surface are physically cleaned and removed and are sucked for more than or equal to 3 minutes under the condition that the vacuum degree is more than or equal to 30 kPa to remove fine chips in surface voids; an adhesive of 0.1-0.12 L/m is sprayed to the cleaned planing and milling working face; a new water permeable concrete mixture is prepared, paved on the planing and milling working face sprayed with the adhesive and is compacting-molded, a laminating film is cured for 28 days, namely, the regeneration of the blocked permeable con |
