Description
Technical field
The invention belongs to traffic engineering construction technique field。
Background technology
In recent years, deck paving was quite subject to the attention of all circles, and part deck paving occurs that some damage。According to investigation, asphalt bridge deck chief destructive reason is as follows:
L () cement concrete bridge deck plate or leveling layer construction quality are poor, cause bitumen layer and concrete pavement layer to cohere bad。
(2) cement concrete bridge deck plate flatness is poor, does not set leveling layer, causes asphalt surface course became uneven, and compactness is inconsistent, and the compound at the thin place of pave-load layer produces serious isolation。
(3) cement concrete bridge deck plate or leveling layer end face, making waterproof-and-binding layer and asphalt when being not yet completely dried, moisture heat can become steam, makes waterproof-and-binding layer produce the phenomenon such as bulge, decortication。
(4) owing to the effect etc. of freeze thawing is repeated in seasonal frost region, waterproof layer material is unsatisfactory for floorings (beam) and concrete pavement layer deformation requirements are damaged inefficacy。
When " highway bridge and culvert design general specification " designs by permanent condition ultimate limit states, the design safety grade of highway bridge and culvert, it is likely to produce severity of consequence according to structural deterioration and is divided into three design grades。For this, Water-proof Hierarchy for Deck Pavement should adapt with Bridge Design safe class and climatic environment condition, and bridge security grade is more high, and in the area having frost, the requirement of Waterproof Layer Spreading of Bridge Surface is more high。In order to prevent rainwater infiltration immersed structure thing, select good waterproof layer, consider to mat formation the pull strength of force analysis and external corresponding Colophonium class waterproof construction system and shearing strength requirement simultaneously, require that waterproof layer material is at 25 DEG C of temperature, shearing strength should be greater than 0.4MPa between waterproof layer and bitumen layer or between waterproof layer and concrete slab, and pulling test strength should be greater than 0.4MPa。
Visible deck paving water proofing property layer is not only relevant with the performance of waterproof layer itself, and also with the globality of waterproof material, crack resistance, the cohesiveness of waterproof layer and concrete slab, and the variability that waterproof layer is in work progress, it is conformability relevant that overlapping the slot position processes。China's waterproof layer kind, material are more, and currently mainly waterproof layer material type is: coating film waterproof material, tar sand waterproof layer, slurry seal waterproof layer, waterproof roll。But each of which is all defective。
(1) coating film waterproof material coating thickness is relatively thin, easily punctures film layer, waterproof layer and cutting optimal asphalt Coating combination when rolling bad。Water resistance and interlayer anti-pulling, shear strength are low, it is difficult to ensure requirement。
(2) tar sand waterproof layer has certain porosity, and dense water is poor, and it is poor to combine between waterproof layer and bitumen layer or between waterproof layer and concrete slab, and construction is complicated。
(3) the interlayer force resistance of slurry seal waterproof layer is poor, and waterproof effect is general。
(4) the interlayer force resistance of waterproof roll is poor, and between bitumen layer or and concrete slab between shearing strength relatively low。
Summary of the invention
It is an object of the invention to: a kind of bridge deck water-proof tack coat material and preparation method thereof is provided, it can and bridge surface cement concrete between, have stronger combination between bituminous concrete, increase shearing strength and pulling test strength between waterproof layer and bitumen layer, between waterproof layer and concrete slab。
