Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, a novel pavement base-free seam tape comprises a crack filler 1, a surface tape 2 and a piece of isolation paper 3, wherein the crack filler 1, the surface tape 2 and the isolation paper 3 are sequentially arranged from inside to outside and wound into a roll shape, the width of the isolation paper 3 is greater than that of the surface tape 2, the width of the surface tape 2 is greater than that of the crack filler 1, the crack filler 1 is in a paste shape, the crack filler 1 is fixedly adhered to the back of the surface tape 2 in the middle, the surface tape 2 is fixedly adhered to the upper end of the crack filler 1, the overall thickness of the crack filler 1, the surface tape 2 and the isolation paper 3 is 2-4 cm, the isolation paper 3 is adhered to the outer surface of the surface tape 2, the crack filler 1 is sequentially provided with a polyester felt reinforcing layer 101, an adhesion layer 102 and a first asphalt layer 103 from top to bottom, a waterproof layer 202 is polyurethane sealant, the thickness is 1.5-2.5 mm, the thickness of polyester asphalt felt enhancement layer 101 is 2.5-3.5 mm, top layer tape 2 is from last to being isolation layer 201, waterproof layer 202 and second pitch layer 203 down in proper order, polyester asphalt felt enhancement layer 101, first pitch layer 103 and the inside pitch regenerant of inlaying of second pitch layer 203, top layer tape 2 is flexible bendable, adhesion promotion layer 102 is acrylic resin, thickness is 1.2mm, 3 thicknesses of barrier paper are 1.2 mm.

When the asphalt pavement crack sealing tape is used, the crack 4 on the surface of the asphalt pavement 5 is found, the crack sealing tape is directly used for the pavement crack with the width smaller than 5mm (as shown in figure 4), and the crack sealing tape is used for effectively treating the road section with the crack width larger than 5mm after asphalt is adopted for crack pouring. According to the field situation, a brush and a blower are used for cleaning and drying the cracks (joints) selected to use the joint tape, so that the cracks and the road surfaces within the range of 20cm at the two sides of the cracks on the road surface are cleaned simultaneously, otherwise, the sticking effect of the joint tape is influenced. The surface of the crack (joint) needs to be smooth, and has no protrusion, no depression, no looseness, no broken stone or oil mark, grease and other dirt, and if a pit or a groove exists, the crack (joint) needs to be filled. Cutting a section of surface seam-attaching tape with the length slightly longer than the length of the crack, removing 3 pieces of isolation paper on the back of the seam-attaching tape, keeping one side of the isolation layer 201 of the seam-attaching tape upward after 3-5 minutes according to the air temperature, pressing the seam-attaching tape and two sides of the crack with fingers, adhering the seam-attaching tape from one end until the whole crack 4 is covered, and when adhering, paying attention to the fact that the crack is positioned in the middle of the seam-attaching tape, and at the moment, the crack filler 1 is just completely fused into the crack, and paying attention to the fact that air is not pressed between the seam-attaching tape and the road surface to form bubbles as much as possible. If irregular cracks occur, the tape can be cut off by scissors and can be adhered according to the trend of the cracks. Preferably, an 80-100mm overlap is formed at the juncture of the welt strips. After the seam-sticking belt is stuck to the pavement crack, the seam-sticking belt is pressed and stuck to the ground by using an iron roller to ensure that the seam-sticking belt is combined with the pavement into a whole. Air bubbles and wrinkles cannot be generated so as to ensure that the seam-attaching belt is fully combined with the pavement.

In conclusion, the novel base-free seam-covering belt for the pavement enhances the modification performance of asphalt in the production of the traditional seam-covering belt, changes the condition that the seam-covering belt needs base fabric as a foundation, removes non-woven fabrics of a surface layer of the seam-covering belt on the basis of not influencing the wear resistance, makes a pure asphalt product like crack pouring glue, does not need to be heated like the crack pouring glue, and is more convenient in cold construction; can simultaneously replace two products of a joint tape and a joint sealant; the tire-free base cloth and the surface fabric cannot influence the later pavement milling; the construction efficiency is improved due to cold construction, and the smoke is not discharged, so that the construction method is more environment-friendly; the pasty crack filler 1 can be better attached to the road surface, so that the polymer can be better extruded into the crack, and the crack is protected from being damaged; the high temperature resistance and low temperature resistance are excellent; can be bent at will, and the turn warping rate is low; the service life is long.
