Abstract
The utility model discloses the high-strength affixing kerfs belt in a kind of road, relate to road upkeep field, including five-layer structure, be followed successively by wear-resistant protective layer, high molecular polymer coating and sealing coat under coating, enhancement layer, high molecular polymer from top to bottom.This utility model affixing kerfs belt thinner thickness, effectively reduces road pavement flatness impact during using；High-strength pulling-resisting enhancement layer designs so that it is have stronger anti-crack ability；Wear-resistant protective layer designs, and strengthens itself and road surface friction force, folding, pushing phenomenon occurs during effectively preventing from using；Polymer coating designs so that it is having preferable stress absorption and seepage capability, this affixing kerfs belt is the integrated application of several measures by preventing crack on existing highway.
Description
Technical field:
This utility model relates to field of road maintenance, is specifically related to the high-strength affixing kerfs belt in a kind of road.
Background technology:
In recent years, along with highway is flourish with urban transportation cause, maintenance of surface ratio in highway communication is the heaviest.China's Asphalt Pavement Base design uses semi-rigid type base form mostly, semi-rigid type base has the advantage that its intensity is high, bearing capacity is big, but also it is easily formed temperature contracting, desciccation crack, ooze under rainwater after pavement cracking, roadbed and pavement strength is made to reduce, under the effect of traffic load, accelerate expansion and the generation of pavement crack, also can bring the bigger harm such as purt slurry, depression, check crack to road surface simultaneously.
Affixing kerfs belt well can transmit, prevent from oozing under moisture in inhibitory reflex crack, thus is increasingly being used in asphalt pavement structural layer.Affixing kerfs belt is usually and is made up of sealing coat, Colophonium, tire base, high molecular polymer, high-strength high temperature-resistant fabric, and through the cracking resistance with autohension of special web apparatus extrusion cladding and waterproof material.This structure is by several waterproof, organic assembling of crack control measures such as the geosynthetics being used alone on present highway, stress-absorbed materials, is the optimum organization upgrading products of Current Highway interlayer cracking resistance, waterproof material.
Utility model content:
Technical problem to be solved in the utility model is to provide a kind of and has high-strength pulling-resisting, high temperature resistant, waterproof, energy dissipating, self-adhesion and the road high-strength affixing kerfs belt good with bitumen compatibility.
Technical problem to be solved in the utility model uses following technical scheme to realize:
The high-strength affixing kerfs belt in a kind of road, including five-layer structure, is followed successively by wear-resistant protective layer, high molecular polymer coating and sealing coat under coating, enhancement layer, high molecular polymer from top to bottom.
Described wear-resistant protective layer is the polyethylene polypropylene cloth with Process, and intensive aperture increases its frictional resistance, and in use interlayer is not easily formed slip.
On described high molecular polymer, under coating and high molecular polymer, coating is made up of macromolecule polymer material.This coating structure has self-adhesion and waterproof action.
Described macromolecule polymer material is filled stone powder, modified rubber powder by modified pitch of high polymer and mixes from viscous oil.The material of described enhancement layer is polyester fiber woven fabric, has high-strength pulling-resisting character.
Described sealing coat is high-strength PP film.
The thickness of described affixing kerfs belt is 1.0-1.5mm.
The beneficial effects of the utility model are:
(1) thickness of this practicality affixing kerfs belt is 1.0-1.5mm, effectively reduces road pavement flatness impact during using；
(2) in this practicality affixing kerfs belt, coating of high molecular polymer has certain viscoelastic material, there is preferable low temperature flexibility, it is laid on bituminous paving interlayer, be equivalent to be provided with viscoelastic layer, at crack, tension expands to wider range by biopolymer layer in Anticracking plaster, plays the effect absorbing tensile energy；
(3) the wear-resistant protective layer design of this practicality affixing kerfs belt; overcome geotextiles, glass fiber grid in paving process, to cause passage, fold; the problem affecting up-down structure layer adhesion, the design of high-tensile enhancement layer can resist the destruction in more serious crack.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the preparation technology flow chart of the high-strength affixing kerfs belt of this utility model；
Wherein: 1-wear-resistant protective layer；Coating on 2-high molecular polymer；3-enhancement layer；Coating under 4-high molecular polymer；5-sealing coat.
Detailed description of the invention:
For the technological means making this utility model realize, creation characteristic, reach purpose and be easy to understand with effect, below in conjunction with being specifically illustrating, this utility model is expanded on further.
As shown in Figure 1, 2, the high-strength affixing kerfs belt in a kind of road, including five-layer structure, it is followed successively by coating 4 and sealing coat 5 under coating 2 on wear-resistant protective layer 1, high molecular polymer, enhancement layer 3, high molecular polymer from top to bottom.
The thickness of described affixing kerfs belt is 1.4mm.
Described wear-resistant protective layer is by 80g/m2Polyethylene polypropylene cloth forms.
On described high molecular polymer, under coating and high molecular polymer, coating is by SBS modified pitch (No. 70 Colophoniumes of A level add 10%SBS modifying agent), stone powder, modified rubber powder, mixes by proportioning 50:30:10:10 from viscous oil.
Described enhancement layer is by 200g/m2High-strength polyester fibers woven fabric forms.
Described sealing coat is high-strength PP film.
Of the present utility model ultimate principle and principal character and of the present utility model advantage have more than been shown and described.Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; described in above-described embodiment and description, principle of the present utility model is simply described; on the premise of without departing from this utility model spirit and scope; this utility model also has various changes and modifications, in the range of these changes and improvements both fall within claimed this utility model.This utility model claims scope and is defined by appending claims and equivalent thereof.
