Quick repairing method of old cement concrete pavement
The invention discloses a quick repairing method of an old cement concrete pavement. High-grade Portland cement or special cement, a mixed aggregate, a self-made aqueous polymer emulsion and a retarder are manually or mechanically mixed at normal temperature, a high-adhesion quick-drying powerful ultrathin cover surface can be rapidly formed by adopting a quick scraping or spraying method, and is tightly combined with an old concrete surface layer into a whole. The quick repairing method disclosed by the invention is applied to quick repairing of a municipal administration cement pavement; the characteristic that a conventional cement concrete road reaches design strength by curing for 28 days when being repaired is changed, the old cement concrete pavement is finally settled at temperature of 25 DEG C for 2-4h by adopting the quick repairing method disclosed by the invention, the problem of traffics is solved; meanwhile, the repaired old cement concrete pavement is convenient to construct and powerful in adhesion, and resists heat and frost.
