Infiltration, then can road pavement overall structure play a very good protection.
It should be noted that one kind can be provided to implement the utility model embodiment by the process of following regulation structure
Attachment device for bridges and culverts 700 and roadbed 710.
First step cuts notch.According to 700 their location temperature change of bridges and culverts, concrete shrinkage and creep and load
Stroke under effect requires to determine that notch size, including groove width, depth, length generally laterally penetrate through.Determine notch
Positions and dimensions after, draw lines on position to be cut, then along wire cutting, retention groove mouth line is parallel, to guarantee seam
Beauty.
Second step, cleaning drying heat and soften notch.After notch is cut, groove sundries is cleared up, and dried with hot wind
Do, cut the part of two sides loosening；Notch two sides asphalt surface course is heated with heated air circulation device, is softened it, pays attention to control
The temperature of baking, in order to avoid ageing of asphalt.
Third step installs transverse joint plate 200.Transverse joint plate 200 clogs seam bottom using polyurethane foam board, guarantees seam
Place is completely embedded, it is ensured that graded broken stone and rubber-asphalt mixture will not be fallen from sealing.
Four steps pours rubber-asphalt mixture lower layer and deforms adjustment layer.It will meet after cleaning, drying, screening first
The graded broken stone of corresponding requirements is heated to 190-200 DEG C, guarantees its crush values no more than 25%, flat-elongated particles content is less than
15%.Then it is heated to 160-165 DEG C after adding age resister and micro-expanding agent in rubber asphalt, by the continuous level of confidentiality of heating
It is mixed and stirred with metaling and rubber asphalt molten mass, the rubber asphalt of flowing has filled up the gap between metaling, and will be loose
Metaling be bonded together.In mixture, rubber asphalt is continuous entirety, and metaling is then embedded in continuous entirety
In, the gap between metaling is filled by lastics substantially, so that voidage is very low, can make up suspension compact structure profile
Material.It should be compacted in time with plate device after the completion of last making.Due to rubber-asphalt mixture have at room temperature it is good
Elasticity is had in time so rolling, to prevent from causing compactness deficiency to form early damage since temperature declines.
5th step, can be by repeating above four step the step of, to carry out the carrying of elastoplasticity seam body media layer damage
The construction of layer and upper layer stress absorbing layer, until upper layer construction terminates.Under, in, upper three-decker collectively constitutes elastoplasticity and connects
Stitch body.Last open to traffic.It can open to traffic after pavement temperature drops to 40 DEG C or less.
The utility model provides a kind of attachment device for bridges and culverts 700 and roadbed 710, by roadbed 710 and bridges and culverts
Groove body 100 is set between 700, then by transverse joint plate 200, the first packing layer 300, the second packing layer 400 and third packing layer 500
