Emulsifiers

Bitumen emulsions are modern, high-performance road construction materials based on bitumen and water, representing an alternative to conventionally used hot, heated bitumen.

Compared to hot bitumen, emulsions offer significant advantages when used in road construction works.

From a technological perspective, bitumen emulsions are simple, convenient, and safe to use, less dependent on adverse weather conditions, significantly improve the quality of road surfaces, and extend the road construction season by 1.5–2 months compared to bitumen.

The quality of bitumen emulsions directly affects the results achieved on the road.

To produce high-quality bitumen emulsions, the following are required:

• Reliable equipment: bitumen emulsions are produced using emulsion plants, with the colloid mill being the “heart” of any emulsion plant. The uniformity of grinding, average particle size after grinding, and fineness of dispersion depend on the mill's design features and settings.
• A properly selected formulation – the ratio of bitumen, water, emulsifier, and other additives in the composition.
• High-quality emulsifiers that ensure emulsion stability, stability during storage and transportation, and the required “working life” when in contact with aggregate materials – meeting expectations for the performance of the emulsion on the road.

“AMDOR-EM” emulsifiers have been used in road construction for 25 years, both in Russia and abroad. More than 150 bitumen emulsion manufacturers use “AMDOR-EM” emulsifiers.

The modern range of “AMDOR-EM” emulsifiers ensures high-quality bitumen emulsions and their compliance with the applicable GOST R 52128-2003 and GOST R 55420-2013 standards.

The dosages of “AMDOR-EM” emulsifiers are comparable to those of leading imported products, while the technological properties of the emulsifiers themselves often exceed those of imported products.

We have a laboratory-scale emulsion plant, as well as the auxiliary equipment required for the regular production and analysis of bitumen emulsions.

“AMDOR” specialists continuously work on developing bitumen emulsion formulations, provide support during operation of emulsion plants, and conduct material testing.

The most in-demand “AMDOR-EM” emulsifier grades are summarized in the table:

The exact amount of emulsifier is determined by the nature of the aggregate material and the quality of the bitumen.

The use of “AMDOR-EM” emulsifiers makes it possible to:

• produce consistently high-quality bitumen emulsions;
• reduce energy and labor costs due to the simple application of the emulsifiers;
• save up to 30% of bitumen by improving the wetting and coating of the aggregate material;
• reduce the cost of the final product due to the low emulsifier dosage.

An undeniable advantage of “AMDOR” emulsifiers is the year-round availability of products in warehouses throughout the Russian Federation.

The company's technical specialists, with many years of experience using “AMDOR” products with various binders and aggregate materials and on various emulsion plants, successfully handle all the tasks faced by our customers.

We provide engineering and technical support for the use of “AMDOR” emulsifiers, as well as:

• conduct laboratory and pilot-scale industrial testing of emulsifiers at the customer's site;
• select a bitumen emulsion formulation in our laboratory using our own “Davial-LaProm” emulsion plant.

Application of AMDOR Emulsifiers

• “AMDOR-EM” emulsifiers work with all types of emulsion plants.
• “AMDOR-EM” emulsifiers do not require additional heating.
• They have an optimal physical state for trouble-free use under any production conditions.
• Hydrochloric acid is used to regulate the pH of the aqueous phase. 

Transportation and Storage of Bitumen Emulsion Emulsifiers

“AMDOR” emulsifiers are supplied in 216-liter metal drums and 1,000-liter polymer containers.

“AMDOR” emulsifiers are stored in enclosed warehouses at an ambient temperature ranging from -35 to +50 °C.

When stored in sealed packaging, the product remains stable for two years.

 We solve tasks of varying complexity for our customers and always strive to exceed their expectations.
