Abstract
The invention relates to a method for treating a pitted surface, transverse and longitudinal cracks, pot holes and edge and angle failure of a white pavement. The method comprises the following steps of cutting cross-shaped grooves on the surface of a pitted surface of a white pavement by a grooving machine, cutting grooves at transverse and longitudinal crack broken plates along a crack growth direction, cutting square or rectangular grooves at pot hole and edge and angle failure positions, cleaning the interiors of the grooves, feeding stirred mortar concrete into the grooves, carrying out tamping, screeding, compacting and galling, covering a plastic cloth on the treated positions when the surfaces are slightly dry, and carrying out maintenance until the seventh day. The method has simple processes and good pavement repairing effects, is free of large-area removal or whole-block removal because of a small damaged position of the white pavement, saves fund, and has a short construction cycle. The white pavement treated by the method is firm, has wear resistance, is not damaged easily and has a service life longer than before.
Description
Technical field: the present invention relates to the vertical transverse cracks of a kind of white pavement pitted skin hole groove and gnaw limit arrisdefect treatment process method.
Background technology: at present; existing road white pavement; often there will be damaged place, as there is some breakage on road surface, just take the method for large clearing; to cheating groove or gnawing limit arrisdefect and take entire plate to remove; to the serious way that also will take entire plate to remove of the disconnected plate of vertical transverse cracks, to the processing of pitted skin, can only take entire plate to remove, not only the construction period is long; affect traffic, but also wasted a large amount of funds of building the road.
Summary of the invention: the object of the invention is to overcome above-mentioned shortcoming, provide the vertical transverse cracks of a kind of white pavement pitted skin hole groove to gnaw limit arrisdefect treatment process method, it has mainly solved the processing that white pavement occurs damaged hole groove or gnaws the disconnected plate of the vertical transverse cracks of limit arrisdefect and pitted skin, the way of taking monoblock to remove, construction period is long, affects the problems such as traffic.The object of the present invention is achieved like this, the processing to white pavement pitted skin, and the bisque loosening on pitted skin top layer carries out cross cutting with gaining machine, groove depth 3-10mm, spacing 8-12mm, is carved into latticed; Adopt steel wire abrasive brush to polish, till loosening epidermis polishing totally, with giant, rinse, be flushed to without dust non-loosening thing; With small-sized mortar mixer, stir mortar, the water of mortar, ash, sand will be prepared burden in strict accordance with national standard ratio, cement adopts double quick high-strength cement, cement grade is 75-80#, prepares material rear with artificial screeding and compaction surface, needs the road surface of plucking to carry out plucking, the road surface Troweling press finishing that does not need plucking, on surface, add a cover Polypropylence Sheet after slightly dry, health to seven day, reaches 28 days intensity of ordinary Portland cement.The treatment process method of the disconnected plate of vertical transverse cracks: by crack orientation, slot, the groove edge degree of depth 3-5cm, the groove middle crack degree of depth 6-10cm; After fluting, in groove, put into indented bars, transverse cracks need not descend reinforcing bar, reinforcing bar density and diameter are determined by former pavement design requirement, in groove, to rinse well, adopt double quick high-strength cement, cement grade 75-80#, mixing concrete is squeezed in groove, carry out vibration compacting, smear applanation surface, plucking, plastic covering cloth health seven days.Hole groove, gnaw limit, arrisdefect treatment process method: first by hole groove, gnaw limit, arrisdefect is cut into square or rectangular slot, the interior degree of depth 6-18cm of hole groove, grooving outward flange 3-5cm; Remove broken concrete, rinse well, mixing strong concrete is put into groove, and cement grade 75-80# carries out vibration compacting, smear flatten, plucking, the health of plastic covering cloth is till seven days.This invented technology is simple, the old pavement that adopts this technique to repair is effective, make old white pavement because of breakage, a bit just not take large clearing or entire plate to remove, can save a large amount of funds of building the road, conditioned time is short, can little half range or area construction, do not affect traffic, construction period is short, Ke Duo troop constructs, and to old white pavement maintenance, can reach disposable radical cure effect, and after repairing, the firm abrasion resistance in road surface is good, not fragile, the life-span that can improve 20%-50% application life on the Bi Yuan road surface, road surface after reparation.
