Infiltrating bitumen or primer is effective for special purposes and more in road construction. As its name suggests, this type of bitumen is classified based on the results of penetration and softening point tests. In this article from the blog of Gharb Nikan bitumen company, join us to share with you the necessary information about the use of penetrating bitumen, its benefits, specifications, grades, as well as its share in the Gilsonite sales market.
What is primer or penetrating bitumen?
To get to know penetrating bitumen, we must first understand the concept of bitumen itself. Bitumen or bitumen is a black, paste-like material and a derivative of petroleum, which is generally used for insulation and asphalt. Bitumen has different types, each of which has different uses.
Permeable bitumen is a thin layer of mixed bitumen with low or medium viscosity (slow flow) on a sandy surface. It is also widely used in road construction due to its adhesive properties and is available in different grades.
Types of penetrating bitumen
The classification of penetrating bitumens is done according to their penetration degree and softening point tests. Based on the range of penetration, in areas where the weather is warmer, harder bitumen with a lower degree of penetration is used, and in areas with a colder climate, looser bitumen with a higher degree of penetration is used.
This is despite the fact that in recent years, hard bitumen has been used more than soft bitumen in road construction activities, which is due to the production of asphalts with higher properties in hard bitumen.
Primarkt in the road construction industry
As mentioned earlier, penetrating bitumen is used more than anything else in the road construction industry and on the road surface; Of course, this product is sometimes used in some other industries as well. The properties of rheology, cohesiveness, adhesion and durability are very important to measure the efficiency of bitumen.
The application of penetrating bitumen in road construction and asphalt is to consolidate the surface of the sandy road to facilitate the adhesion of the asphalt layer to the road body; For this reason, Primakt penetrating bitumen is spread on the surface of the sandy road to penetrate into its voids.
Advantages of infiltration coating in road construction
It is necessary in road construction operations, a path that is marked with a width and is supposed to be passed by users; Prepare to travel. This operation is done in three stages: base, sub-base and pavement.
Infiltrating bitumen is used to prepare the sand surface of the road with the aim of spreading cold or hot asphalt layer. In this type of road construction, a thin bitumen layer is used to seal non-asphalt surfaces to protect the underlying layers from wet weather; Then the materials in the bed are connected and the surface of the bed becomes harder, which is called the integrity of the granular bed.
Penetrating coating has the feature that it can cover the loose particles in the base layer, and in this way, less dust is produced in construction activities and the work process becomes easier.
The use of penetrating bitumen in asphalt is to eliminate the holes and reduce them. At the same time, with this work, it creates continuity between the base and the asphalt grains. After the infiltration coating, the next pavement layer is applied.
Characteristics of penetrating bitumen
The high-quality penetrating coating material consists of small particles that have a low surface tension in the emulsion and allow them to penetrate into the capillary cavities. In order to choose a suitable penetrating bitumen, the ambient temperature, relative humidity, wind speed, bitumen curing time and surface texture of the road bed should be measured.
Usually, soluble bitumen used as infiltration coating includes MC30 and RC70 for cold weather with low flow rate; MC250, MC70, MC30 for mild and warm weather; MC30, MC70, RC70 for sand surface texture with low flow rate and finally bitumens with more flow rate such as MC250 for sand surface texture are coarse-grained and open.
The amount of bitumen used in Primekt for 24-hour absorption is 0.9 to 2.25 liters per square meter. Also, the temperature of using penetrating bitumen is higher than 15 degrees Celsius.
Permeable bitumen grades
Penetration grading system used to determine the consistency of semi-solid bitumen; It offers different grades of penetration rating. Permeable bitumens used in road construction are 60/70 permeation grades (penetration degree between 70 and 60 and softening point between 49 and 56 Celsius).
Due to the importance of the quality of bitumen on the performance and life of the asphalt coating, the price of penetrating bitumen is also affected by its quality and penetration rate. In addition to the above, the economy and international political changes also affect the price of bitumen and Gilsonite. Due to the use of penetrating bitumen in road construction and other strategic infrastructure industries, penetrating bitumen is considered as one of the most important foreign currency-earning products for export.
