Description
Technical field
Making be the utility model is related in the paving structure technical field on cement concrete bridge deck, be specially a kind of resistance to
Long cement concrete bridge floor composite pavement structure.
Background technology
In recent years, with the development of communication, the volume of traffic and heavy vehicle are more and more, in heavy duty, overload, canalization etc.
Bridge and its deck installation structure durability directly carried are faced with acid test under traffic environment.
It with cement concrete or bituminous concrete is a kind of layer of the main material-paving on floorings that deck paving, which is,
Shape structure, it, which should be played, provides vehicle safety, the smooth, function comfortably run, plays protection floorings again, maintains or prolong
The effect of long bridge service life.Therefore, for resisting the erosion damage of outer bound pair bridge main body structure, it may be said that design
Together with will being cement concrete bridge or floorings with good deck paving of constructing " artificial barrier ".
For asphalt concrete pavement, due to deck paving in current Chinese code of practice and waterproofing design or blank, in work
It is generally consistent with normal section for ease of construction, deck installation structure type in journey practice.Dripped more using close-graded or SMA
The form of mating formation of blue or green concrete, 4~8cm of pavement thickness are soft only with one layer of weak pitch class between pave-load layer and floorings
Property binder course（Such as emulsified asphalt, polyurethane solvent-borne type pitch bonding agent etc.）.This kind of pavement structure system, even if pave-load layer uses
The modified asphalt binders or SMA mixture of function admirable, but due to can not be formed between asphalt pavement main body and floorings
Effect connection, under carload effect, pave-load layer easily occurs delamination and causes pave-load layer cracking destruction with floorings.Meanwhile by

The peeling of fast pave-load layer and floorings；On the other hand, the water penetrated between pave-load layer and floorings, will penetrate further into floorings
And in bridge structure, cause the steel bar corrosion of structure, it can also produce freeze-thaw damage, the mechanical property of bridge structure in extremely frigid zones
Decline, bridge durability will be affected.
And for Bridge Surface Paving by Cement, then certain thickness individual layer coagulating cement is directly laid on floorings
Soil, or laid respectively by leveling layer and concrete pavement surface layer, 3~10cm of thickness.Typically floorings and pave-load layer it
Between waterproof layer is not set specially, but the water-proof function of deck paving is realized as pave-load layer by using water-proof concrete.But
Due to some concrete pavement layer thickness deficiency, pave-load layer easily produces damaged in the presence of vehicular load and temperature；And by
Bad and concrete is handled in the water shutoff of contracting seam and construction joint and produces warm plastic forming, and rain, snow-broth will immerse concrete pavement layer
With the concrete component of bridge structure, steel member corrosion is set to bring harm to corrode to bridge structure.
