Why should asphalt pavement tape be used in the early stage of cracking?

Small cracks appear on the pavement at the beginning, and the cracks on the pavement should be repaired in time with the Jiage asphalt pavement tape, otherwise the rainwater will flow along the cracks and seep into the roadbed, and then after the vehicle rolls, the pavement will soon appear larger cracks and even potholes.

This is indeed that, we know this, he rides for a convenient and safe place.

Because if the crack gets bigger and bigger, even if you pour asphalt into it, there will be breath in it later, and the crack will crack again after the breath, and only after the small gap is poured into it can it be fully integrated.

If you want to use it in the crack hand, Liqun is not empty. The large processing can be put into the mold to ensure that there are more quality problems in the future and long-term actions.

Why should the initial asphalt surface course be treated in the crack fracture? If you do this, it will be smooth and look neat.

Minutes should be shaken by others, so the standard configuration of Justice II can be done well.

In this case, you must go to the hospital to see, the doctor is the final word, and you must listen to them.

Avoid water seepage and damage to the quality inside the object.

This is mainly to prevent the concrete from cracking in a large area and then shrinking.

I just checked it for you, but it's to prevent the weather from drying out too hot.

Because if you don't use the Hunting Road Duanfeng Belt to deal with the cracks in the early stage, they will get bigger and bigger, and it is easy to cause damage to the road surface.

You need to use asphalt pavement at the beginning of the crack.

Why use asphalt pavement to treat the cracks when they go out, so that they can be avoided. Cracks appear.

At the initial stage of cracks, asphalt pavement tape is used to treat waterproofing.

In the early part of March, it is better to use asphalt pavement seam tape, which will be stronger.

Choose asphalt pavement seam tape, this is because the seam tape has self-adhesiveness, the construction is very convenient, after removing the separator film, it is directly bonded to the crack site, and after the use of small compaction equipment to stabilize the pressure, the bond with the road surface is more firm, there is no movement, and it can meet the requirements of the upper asphalt mixture paving construction. The jointing tape is attached to the asphalt concrete surface that produces cracks or spalling, which can reduce and block the temperature and shrinkage stress acting on the road surface, so it also reduces the tendency of crack reflection through the surface layer, and the pavement is paved because it isolates the base layer from the upper wear layer, so that the upper layer is free from the influence of multi-directional displacement and shear stress, and is used for highways, bridges, and airports. Waterproof and impermeable effect.

The joint tape is used in the asphalt pavement layer, which can effectively inhibit the upward transmission of cracks, and play the anti-crack and energy-absorbing effect of the joint tape in practical engineering. Asphalt pavement seam tape is a kind of roll-type crack-blocking waterproof diaphragm, with a thickness of about one, which is mainly used to deal with pavement cracks. The pavement seam tape can be directly paved on the pavement cracks, which plays the role of sealing and waterproofing, and prevents the spread of pavement cracks and avoids premature damage to the pavement.

Due to the good stability and tensile strength of the seam tape material, coupled with its strong adhesion force, it is completely combined with the pavement, which effectively prevents the crack expansion and the infiltration of rainwater, thereby reducing the damage of the pavement and prolonging the service life of the pavement.

On the left is the seam tape, and on the right is the anti-crack tape. If you want to know which of these two maintenance materials is better, you must first understand these two.

The difference between the products is **.

Pavement seam tape: Many people also call it road seam tape, Jiage seam tape, etc., etc., I will not give examples one by one. First of all, the seam tape is the main thing.

It is used to patch the cracks in the road surface and prevent water seepage. As a result, many of its advantages are based on pavement seams and waterproofing.

For example, the seam tape is relatively soft, and the crack can be well pasted along the direction of the crack bend during construction, and it has good elasticity. The seam tape is provided on both sides.

The design of the skirt prevents the vehicle from jumping when passing by.

Anti-rip tape: Many people also call it anti-rip tape. Its main function is to stick to the base layer after the milled asphalt pavement. Prevent cracks in the base layer from spreading to the road surface and adding cracks.

wide, which has a requirement for the hardness of the crack sticker. Therefore, the crack resistant veneer layer has a layer of tire machine cloth, which plays the role of crack tensile strength, because the tire machine cloth of the surface layer has one.

The fixed hardness can not flexibly follow the curved direction of the pavement cracks to seal the cracks well.

Overall, both products have their own uses. When it is necessary to apply joints on the pavement, the effect of pavement seam tape is better than that of anti-crack tape. When it is necessary to mill.

When the planed base layer is pasted, the effect of anti-crack tape is better than that of pavement seam tape.

And their waterproof performance is perfect, and the operation method is the same, which belongs to the maintenance material that can be attached to the road only by uncovering the bottom film.

What is the difference between seam tape and rip sticker?

The production process of the seam tape is the same as that of the anti-crack tape, and the anti-crack tape is used for the use of large cracks, while the seam tape is suitable for the treatment of small cracks. You may think that the seam tape is narrower and uses less material, and the seam tape is definitely lower than the anti-crack tape, but in fact, the cutting process of the seam tape is complicated, and the cost is far more than the anti-crack tape, which will be relative. For example, our company produces a lower specification of anti-crack tape, while the same specification of the seam tape is 14 yuan.

As the name suggests, the main difference between crack tape and seam tape is the width is different: "crack paste" (anti-crack tape) is a rubber asphalt molecular polymer waterproof membrane, which is composed of asphalt-based molecular polymer modified materials, pulled fabrics, temperature, and asphalt compatible with the fabric composite, which does not flow at temperature, does not crack at low temperature, and the thickness is generally 1-4mm, and the width is 24-100cm. The seam tape is a kind of roll-up anti-cracking waterproof diaphragm, which is coated with a 2mm thick polymer waterproof membrane on a thick wrinkled heavy-duty polypropylene material, which is rolled and compounded together by a strict process, and is isolated with silicone oil coated paper on the outside of the waterproof membrane in order to prevent the adhesion of the handling process, so the product has a total of three layers of material.

There are four specifications of the width of the seam tape, such as 8 cm, 12 cm, 15 cm and 20 cm, which can be cut or spliced on site according to the seam width and crack needs, and can also be customized according to the requirements of the user.

According to the above explanation, you may have an understanding of the difference between crack tape and seam tape, so what if it is cracked or seam tape according to the width of the crack? Tai'an Zhengze Engineering Materials**** will explain in detail for you:

1. The crack width is within 2mm.

Traditional method: slotless sealing method: heating and cleaning around the crack, using hot pavement grout material for crack surface sealing, the width is not less than 5cm, the thickness is 1 2mm.

Main machinery and equipment: pavement seam filling machine (including hot melt kettle), flame spray gun (lamp). Main Materials:

Pavement grout material (glue).

Product liters: 3-8 cm sewing tape can be used for subsidy.

2. The seam width is more than 2mm.

Traditional method: slotting and filling method: the pavement slotting machine slotting the cracks, the slotting width is generally to remove all the loose parts on both sides of the cracks, the slotting is not less than 1cm, heating, cleaning the cracks and the surroundings, and then using the hot pavement grout material to fill the joints, and ensure that the surface of the pavement sealing width is not less than 5cm, the thickness of 1 2mm.

Main machinery and equipment: pavement grooving machine, seam filling machine (including hot melt kettle), flame spray gun (lamp). Main Materials:

Pavement grout material (glue).

Product liters: can be treated with about 20 cm of seam tape.

3. Wide seam treatment method.

Traditional method: For some wide cracks, when the above method cannot play a sealing role, it should be treated as wide joints. Cutting machine, air pick, dry cutting along the crack direction, breaking the trench width of more than 20cm, depending on the thickness of the pavement to determine, heating, cleaning the trench and the surroundings, the use of molecular anti-crack paste to seal the cracks under the pavement (when the cracks under the pavement are wider, should be filled first), and then according to the pit repair method *** groove.

Product liters: For this wide seam, it can be treated with grouting

With the rapid development of China's economy and the steady improvement of the people's economic level, the country has begun to build a moderately prosperous society, so that more people can live a well-off life. Nowadays, the people's living standards are constantly improving, and more and more rural areas, townships and counties have changed the previous loess roads and paved with new asphalt roads, making it more convenient for people to travel. Asphalt roads are good, but they can also cause cracks and damage to the road.

To repair road cracks, you can't go wrong with choosing Jiage asphalt joints.

Cracks in asphalt pavement are a common problem, and the causes of pavement cracks are varied, including construction cracks, shrinkage cracks, reflection cracks, etc. After customer feedback, the asphalt seam tape is used, the construction process is simple, and the traffic can be opened after construction, and the effect is very good. The operation is convenient and environmentally friendly, and the construction efficiency is very high.

After a winter, no cracking was found.

Moreover, the asphalt seam belt does not flow at high temperature, and does not crack at low temperature. It has been tested that the normal service life can reach 3-5 years, and it will not fall off and crack itself on both sides of the crack due to thermal expansion and contraction of the crack, and permanently maintain elasticity after curing.

Asphalt joint tape can be used not only for asphalt pavement, but also for cement pavement, expansion joints, cutting joints and other disease cracks.

The main performance characteristics of asphalt seam tape:

First, it is convenient to operate, does not require special tools and equipment, and the construction process is simple;

Second, the cost is low, which can save a lot of construction materials, equipment expenses and personnel training costs;

Third, the quality is reliable, with good adhesion and tensile strength, aging resistance, corrosion resistance, low and high temperature resistance, waterproof and moisture-proof and other physical and chemical properties;

Fourth, it is safe and environmentally friendly, composed of polymer materials, and has stable chemical properties.

Asphalt seam tape function:

The polymer material of Jiage asphalt seam tape has certain high and low temperature characteristics, which can make the material not flow at high temperature; At low temperature, it does not crack and keeps the shape unchanged, and at the same time has a good waterproof effect, which effectively prevents and prevents the infiltration of road surface water after cracking on the road surface.

Having said all that, you should know what you should know about asphalt tape now,

Compared with the pavement anti-crack tape, the jag asphalt joint tape has strong adhesion and elastic recovery ability, and will not cause any shrinkage and deformation due to temperature change.
