Asphalt is known as one of the composite materials that has a special place in the road construction industry today and has created a great revolution in road communication and various industries. In fact, the discovery and invention of asphalt has made commuting and transportation much easier. There are different types of asphalt that can be used in many ways with unique features and capabilities. Asphalt coating, commonly known as Topeka asphalt, is the last layer of asphalt that is applied on roads and is directly related to incoming loads and atmospheric factors. In the following article, what is asphalt coating and what are its features will be fully investigated.
What is asphalt coating?
Asphalt coating is actually a liquid coating that is spread on the asphalt surface to protect it from environmental and external factors. Basically, these coatings work like wood colors, etc., with the difference that they consist of materials such as stone, oil, oil, and sand. The oil in this coating keeps the stone and sand together well, and as long as this oil maintains its quality, the asphalt coating will perform well. The use of asphalt coating is the best possible solution for repairing cracks, holes, and damage to the asphalt surface, and this material is capable of completely removing asphalt defects and preventing problems such as water accumulation, etc.
What is the purpose of using asphalt coating?
Asphalts can have different types, such as warm asphalt, cold asphalt, and protective asphalt, each of which has special characteristics and the way of using them will also be different. Asphalts, no matter how high quality they are, after some time and as a result of traffic, pressures, environmental conditions, weather changes, etc., they suffer various damages such as breakage, bursting, settlement, etc. The use of asphalt coating can have different purposes, the most important of which include the following:
- Asphalt coating makes asphalt highly resistant to sunlight and ultraviolet rays and deteriorates later.
- Asphalt coating can seal the asphalt surface well and prevent water and liquids from penetrating into it.
- This material can solve the problems that arise on the surface of the asphalt, such as unevenness, cracks, fractures, etc.
- The use of asphalt coating can make the appearance of asphalt more stylish and fresh.
- Asphalt coating can increase its lifespan.
Types of asphalt coating and its price
Just as asphalt can have different types, asphalt coating also has a high variety and according to the applications and ingredients, it can have different types, and each of them can have a different price due to the type of ingredients, applications, etc.
Since various factors and parameters can have an effect on the price of asphalt coating, it is not possible to give an accurate and specific rate for it. Among the most important factors that have a direct effect on the price of asphalt coating, we can mention such things as the quality of the coating and the type of manufacturing materials, the thickness of the coating, how to use and apply the coating, the type of asphalt coating, the required size and volume of the coating, etc. Due to the current economic conditions of the country, the price of this material, like other types of materials, can change momentarily.
Of course, it should be noted that protective asphalt, which is known as one of the types of asphalt coatings, includes several different categories, the most important of which are single-layer protective asphalt, multi-layer protective asphalt, cold pre-coated protective asphalt, prime coat protective asphalt, protective asphalt There are Tack Coat, Tack Seal Coat and Road Mix Protective Asphalt, and each of them can have unique applications, capabilities and features.
Time to use asphalt coating
Although high-quality materials such as gilsonite and natural and industrial bitumen are used in the production of asphalt today, and modern asphalts are of high quality and have a long lifespan, each type of asphalt can have a certain lifespan and durability, and after some time, it has defects and become different problems. Fresh asphalt has a rich, black and beautiful appearance, but after some time it can become dull, and therefore it is necessary to use coatings and bring back their original appearance. Also, when the asphalted areas are covered with loose sand or there is sand in front of the drainage, it is necessary to use the coating. Due to the presence of oil, coatings can stick stones and sand together and prevent the asphalt from being damaged. In fact, whenever the asphalt has problems and defects such as cracking, fading, breaking, etc., coatings can be used.
The reasons for the importance of asphalt sealing with coating
In fact, when asphalts break, crack, freeze and swell, unevenness, etc., when small and large seams are formed on their surface. The presence of a seam causes water to penetrate the lower layers of asphalt and damage it more, and it will be necessary to use coatings. Among the most important reasons for the importance of sealing asphalts with coating, the following can be mentioned:
- Asphalt coating can reduce the oxidation of asphalt by having different materials and eliminate the negative effects of sunlight on the asphalt surface to a large extent.
- Asphalt coating can prevent water from entering different layers of asphalt and problems such as freezing.
- These coatings can prevent the asphalt from cracking against high pressures
- It saves time, energy and costs.
The final conclusion
Asphalt coating is a liquid coating that is used to cover the asphalt surface and prevent damage, water penetration, bursting, etc. This coating consists of materials such as stone, oil, oil and sand and has the same function as wood glue. Asphalt coating can have different types, and the cost of its implementation will be influenced by factors such as thickness of the coating, size and volume of the coating, quality and ingredients, etc.
