How long does a colored pavement last? Colored pavement to read the answers

The life of the adhesive imported from the ADB polyurethane color pavement can be used for more than ten years, and the current sea-viewing platform in the Hangzhou Bay Bridge is under construction in 2007, and the Shanghai Sheshan Huanshan Greenway is the 2010 World Expo project, which is still intact. Color pavement adhesive has strong weather resistance and strong adhesion, and the total comprehensive quality of this material is not high, and the use effect is good, and it has also received the favor of many customers. It's worth using.

Colored anti-skid pavement is now mainly divided into three types, one is the colored anti-skid pavement of acrylic material, the other is the colored anti-skid pavement of epoxy resin material, and the other is the colored pavement of modified polyurethane material.

Acrylic color anti-slip pavement, hamburger-style construction, resulting in his poor permeability and adhesion, the combination of the bottom layer and the middle layer is not high, coupled with the drying time is too fast, the coating is easy to embrittle, plus the coating itself lacks toughness, once the pavement is hot and cold contraction, it is easy to detach from the pavement and cause the piece to fall off. The service life is very short, and the cost is not cheap.

Epoxy resin color anti-skid pavement, the weather resistance and toughness of the material itself are not very good, after modification, the weather resistance can be improved, but the toughness is indeed no way to improve. Strong adhesion, after encountering thermal expansion and contraction, the pavement will be cracked, and the surface water will penetrate into the bonding layer of the coating and the pavement, and will be eroded by water after a period of destruction, resulting in the separation of the pavement and the coating. The service life is not long, ** high.

Modified polyurethane materials, technology introduced from abroad, through domestic research and development innovation, better adapt to China's road environment, so that the toughness, weather resistance, adhesion, product stability, environmental protection, etc. of the material meet the national supervision and testing standards, and through experiments have proved that the longest service life of the project is 6-8 years and can continue to be used, the general project is about 3 years, the use effect is still very good, and it can continue to be used. The total synthesis of this material is not high, the use effect is good, and it has also received the favor of many customers. It's worth using.

PU-50M color anti-slip pavement adhesive is polyurethane type, and the user response is excellent! Never complained!

1 boring, relieved, comfortable (other words with similar meanings).

2.The first layer (sentence 1), the second layer to "different colors of pavement". The third layer to "very effective". The fourth floor is finished.

3.The third layer of meaning: the color pavement can eliminate the fatigue of the driver, which is very effective for safe driving and reducing traffic accidents.

The fourth layer of meaning: Colored pavement can be combined with the surrounding buildings and environment to beautify the city.

4.Main content: The car and the road are closely related.

The monotonous color of the road surface can make drivers feel tired. The newly researched colored pavement can eliminate driver fatigue, and is very effective for safe driving and reducing traffic accidents. It can also be combined with the surrounding architecture and environment to beautify the city.

Colored pavement.

Cars and pavements are as closely related to the road as fish are to water. As the "armor" of the highway - the road surface is displayed in front of the driver's eyes every day. However, this layer of "armor" is either a black asphalt road or a white cement road.

The monotonous ( ) color of the road surface can make drivers feel tired after driving for a long time. Can we make the roads more colorful? Yes, the newly developed colored pavement can solve these problems.

Laying this kind of pavement is like painting ( ) color, mixing ( ) different colors into the black asphalt material, and paving different colors such as red, blue, yellow, and green pavement. The colored pavement is like a big book, and it will tell the driver: red - there are intersections and settlements ahead; Blue - there is a primary school nearby, watch out for primary school students crossing the road; Yellow - Do not drive fast, speed limit ......This kind of road surface can eliminate driver fatigue, which is very effective for safe driving and reducing traffic accidents.

Can you elaborate on this?

The main reason is that the product types on the market are complex, and users do not know much about color pavement products, resulting in some inferior products using low prices to occupy the market, causing market chaos.

This is either or, or, some people say that it is not but but, but not it is a related word that indicates a juxtaposition relationship, but in the teaching process, students can easily misjudge it as a progressive relationship, a choice relationship or a turning relationship. The reason for this is "not ......It's ......"There are factors that are easy for students to have illusions between this group of related words that indicate juxtaposition and the three relationships of progression, choice, and transition. Without careful analysis, it is difficult to argue.

The average age of a koala lifespan is around 10 to 15 years.

The baby koala lives in a nursery bag until about 1 year old, and the baby koala will continue to live with the mother koala until the next baby koala is born. At this time, the little koala had to leave her mother and find her own field.

If the mother koala does not breed every year, the baby koala will live with the mother for a longer period of time, and the baby koala will have a better chance of survival. After the age of 12 months, the little koala left her mother to create her own home and find her own territory. Sexual maturity by 3 to 4 years, the average age is around 10 to 15 years.

Female koalas generally live longer than male koalas because they are often injured in fights for mates and run the risk of having to move more distances because they need to maintain larger areas, taking up larger barren soils and eucalyptus forests.

This makes the average age of koalas more misleading, as some koalas live no more than a few weeks or months, while others live for life. Koalas who live in a quiet environment will live longer than those who live on the outskirts of cities.

Some estimate the average lifespan of adult male koalas at 10 years, however, some sub-adult koalas scattered along highways or on the edge of residential areas have an average lifespan of only 2 to 3 years.

Due to the sharp decline in koala populations, there was a loss of genetic diversity in history, and the extinction of giant koalas dating back to the late Pleistocene, which led to a certain inbreeding of koalas in their reproduction.

Ultra-thin color warning anti-skid pavement products have many advantages that other materials cannot match, just like a good car needs maintenance every day on the road.

1. The super color warning anti-skid pavement adopts a special material bonding process, and it is inevitable that there is a small bonding area, and the aggregate falls off after being rolled by the vehicle, which is a normal phenomenon with a cycle of about 30 days. After the new pavement is completed, it needs to be cleaned once every three days and once a week for 20 days.

2. If the colored anti-slip pavement is contaminated with oil, you need to use a specific oil cleaner and clean it directly.

3. If there is a small advertisement sprayed, you can directly spray the topcoat with the color of the color road on it.

4. Dust treatment, rinse with water.
