Technical field
The present invention relates to building material technical fields, and in particular to a kind of cold area's quick patching material for cement concrete pavement
And preparation method thereof.
Background technique
The cement concrete pavement of northern China Han Qu (such as Heilongjiang Province), in season alternation, deicing salt and driving
Under the influence of the composite factor of heavy-duty vehicle frequently acted on, commonly using less than 1 year or in two years, there have been different journeys
The decortication of degree undisguisedly damages.Take the form of: cement concrete pavement surface fine aggregate scatters and disappears, coarse aggregate exposes, and area is in 1m2
More than.Although the problem of this destruction is not pavement structure, its requirement for influencing driving flatness and driving comfort, greatly
Ground shortens the service life on road surface；In addition, having an effect on road surface beauty.
China existing " highway cement concrete pavement maintenance technology specification (JTJ 073.1-2001) " and " highway cement
Concrete road surface design specification " regulation, the modified pitch that such disease generallys use 20-40mm thickness are dilute in (JTG D40-2011)
The Concrete Overlay of slurry sealing or at least 80mm thickness is punished.
Slurry seal is to stir emulsified asphalt, the aggregate for meeting gradation, water, filler and additive by certain design proportion
Slurry mixture is mixed, is equably paved on road surface to be processed, need to be wrapped, be demulsified, bleed, the processes such as evaporation and solidification
It is firmly combined together with former road surface, construction method is more complex, and the used time is longer.It is designed according to Concrete Overlay,
It is required that overlay thickness not be preferably less than 80mm, and milling or feather plucking cleaning after surface apply adhesive, make overlay with it is old
Concrete topping combines integral；Man-hour requirement is applied sufficiently to vibrate and strike off；Watering health at least 14 days, daily watering 3~4
It is secondary.
Above-mentioned existing Cement Concrete Pavement Maintenance material, there are consumptive material demand is big, needed for engineering method complexity and health
The problems such as time is long is unfavorable for that maintenance task is rapidly completed and realizes the purpose that quickly resumes traffic, be further improved.
Summary of the invention
The embodiment of the present invention is designed to provide a kind of cold area's quick patching material for cement concrete pavement, to solve
The above problem of existing Cement Concrete Pavement Maintenance material.It is used for cement concrete pavement decortication undisguisedly damage quickly repair
