Which bitumen does not need heating?Buy bitumen in bulk at best price

Functional classification for bitumen selection has been developed by SHRP. In this classification, which is based on recognizing the behavior of bitumen and its functional characteristics, with the characteristics of resistance to deformation, resistance to cracking due to cold, resistance to cracking due to fatigue, prediction of how hard bitumen in Asphalt plant and when preparing the asphalt mixture, how the bitumen hardens over time and with the tests specified in the specifications, and the appropriate bitumen according to the temperature of the project site, the amount of traffic, loading speed and Geographical location is selected. Each type of bitumen is determined by two positive and negative numbers, the positive number is related to the average of seven consecutive days with the highest pavement temperature and the negative number is the minimum pavement temperature in degrees Celsius.

Which bitumen does not need heating?

These bitumens are obtained by dissolving one of the solid bitumens in different solvents and this operation is done in order to reduce the viscosity of the bitumen. Liquid bitumens harden and become primary after consumption and evaporation of solvent. These products are also classified according to viscosity. Solvents used in the preparation of these products may be light, medium or heavy petroleum materials, such as naphtha, lamp oil and diesel, respectively.

Liquid bitumens are divided into 3 categories, each of which has 6 types of products:

1- Instant liquid bitumen

These types of bitumens are obtained by diluting 85/100% of petroleum products such as naphtha, and because their solvent evaporates soon under normal conditions, they are called quick-setting bitumen. Types of bitumen in this category are:

RC0 – RC1 – RC 2 – RC3 – ​​RC4 – RC5

2- Slow-moving liquid bitumens

These liquid bitumens are obtained by dissolving 85/100 bitumen in a solvent such as lamp oil, and because their solvent evaporates later than the previous type, they are called retarder liquid bitumens. Types of these bitumens are:

MC0 – MC1 – MC2 – MC3 – MC4 – MC5

3- Delayed bitumen

These bitumens, which are obtained by dissolving 85/100 bitumens in heavy solvents such as gasoil or Fueloil, their solvent does not evaporate after consumption, but gradually hardens after decomposition. Types of this type of bitumen are:

SC0 – SC1 – SC2 – SC3 – SC4 – SC5

In addition to the above-mentioned bitumens, other liquid bitumens whose viscosity is about the viscosity of the mentioned liquid bitumens are prepared. The solvent for these bitumens is the same solvent mentioned above.

Types of these bitumens are S125 which is prepared with light solvent (naphtha) and also bitumens: Gasoil or Fueloi black oil.

Which have medium solvent (lamp oil) and 150/100 CB bitumen which is prepared from 40/50 bitumen.

New standards for soluble bitumen have not been extended in the UK. However, a very large volume of soluble bitumen is produced and consumed in this country, and this trend will continue until the unknown future. The reason for not renewing and publishing the new version of the standard for these bitumens is environmental issues and rising oil prices, and consequently valuable solvents such as kerosene and gasoline. On the other hand, the emergence of tear gas technology is in full swing and has no adverse environmental effects. In Iran, the negative effects of soluble bitumen on the environment have been realized, but for technical reasons, bitumen has not yet found its place and MC-250 soluble bitumen is widely produced. Soluble bitumens are obtained by mixing bitumen with a degree of penetration of 70/100 or 160/220 with kerosene to reach a certain viscosity. Soluble bitumens with flow time (in seconds) are named and classified using a standard bitumen viscometer (STV). Three classes of soluble bitumen are available in 50, 100 and 200 seconds. Most of the soluble bitumens are used in surface asphalt and many of them are used in standard and miscellaneous asphalts. For more information about the best quality bitumen, visit our website.

bitumen suppliers uk is graded based on performance at different temperatures. LTPP provides a specific algorithm for calculating asphalt temperature based on the respective air temperature. With this algorithm, the maximum and minimum temperature of asphalt is calculated and the best bitumen that works at this temperature is selected.
