In the road construction industry, bitumen emulsion is used more often than bitumen. This cohesive material was invented in the USA and it has been used for over half a century all over the world as one of the chief components of modern road construction materials. Bitumen emulsion serves as the cohesive material for theRead More

A new age in road construction began on 9 May 1922. Hugh Alan McKey registered the first bitumen emulsion patent. Within several years the application of this new material significantly changed road construction. The amount of bitumen emulsions made in France in 1923 was several hundred tons. In 1924 it increased to 2500, and toRead More

Asphalt emulsions have been in existence for almost 100 years in the United States and the rest of the world. They were first developed in the early 1900s, used in road applications in the 1920s, with continued growth due to World War II and the energy crisis of the 1970s. Asphalt emulsions have found theirRead More

Different types of bitumen emulsions are applied in different industrial processes. Some of the processes include: The priming of the old pavement before applying asphalt or concrete; To prepare cold asphalt mixes; To “surface treat” roadways; To provide thin protective coatings; For patching roads; For waterproofing building foundations and structures; and For installing and repairingRead More

Water-bitumen emulsion is a highly dispersed dark brown material made by atomization of bitumen in water solution of an emulsifier. Such methods of bitumen thinning as organic solutions and hot mastics are prohibited in several European countries due to environmental and health hazards. A better and more efficient method is emulsification. The process is becomingRead More

Pit roads, crossings and driveways are by nature very dusty. In the general case, the amount of dust kicked up into the air depends on the surface of the road, its condition, weight and speed of vehicle movement. A large amount of dust in the air causes accelerated engine wear, limits visibility and causes seriousRead More

The main component of pastry, which significantly defines the quality of the dough is flour. Most of such products require flour withRead More

Most substances used in households and industry are dispersed systems (solid particles or droplets suspended throughout another substance) or solutions, where mixing takes place at the molecular level. Examples of suspensions are mortar mixture, paint, white glue or bitumen emulsion used for waterproofing works. What is bitumen emulsion? Bitumen is a hydrocarbon resin (derived fromRead More

The main objective of laying asphalt concrete mixtures as a road surface is to ensure its adhesion to the bottom layer. A practical solution to this problem is -using bitumen emulsions. Bitumen emulsion disperse system consists of: bitumen and water. Thus the smallest particles of bitumen are dispersed in water without being mixed with it.Read More

Tack coat is an important step in preparing the surface for asphalt concrete or surface treatment, ensuring reliable traction between layers. Priming is done with liquid bitumen or emulsion. The benefit of emulsion is its low viscosity. This ensures an even distribution over the surface and 20-30% economy of bitumen. The use of cationic emulsionRead More

The function of bitumen emulsion is to form uninterrupted film of bitumen after breaking. The rate of this process depends on the reactive ability of the emulsion and the stone surface, as well as weather conditions, such as temperature and humidity. Bitumen emulsion are classified according to their reactive ability. Fast breaking emulsion separate immediatelyRead More

Motorways are the main means of ground transportation. Damp weather complicates traffic on dirt roads, limiting their throughput. Regular technology of ground stabilization with bitumen emulsions is performed at optimal humidity. In this case, part of the water from the emulsion is absorbed by the ground, which makes for uneven distribution of bitumen in theRead More

Petroleum bitumen is widely used in construction. It includes materials for  roofing, waterproofing, air tight material, piping protection (and other types of anti-corrosion and even radiation production), materials for road top, surfacing of canals, settling ponds, sludge collectors etc. Despite the growing production of bitumen, it is still in short supply. Some of the supplyRead More

Emulsions are colloidal dispersed systems, where one liquid is dispersed in another in the form of small droplets without mixing. Examples of such emulsions are bitumen or tar and water. The content of bitumen or tar in road construction emulsions can reach 50-65%. Emulsion with bitumen or tar content above 70-75% are referred to asRead More

The two major groups are water-in-oil and oil-in-water emulsions. Besides, bitumen emulsion are classified according to the rate of separation: fast, medium and slow breakdown emulsions. The first groups includes emulsions which separate soon after contacting the mineral material. The smaller the particles of the mineral material, the faster the breakdown. Medium breakdown emulsions separateRead More

The results of many research efforts demonstrate that modifying bitumen with polymer additives results in a polymer modified bitumen (PMB) which under stress behaves as a reinforced material. Polymer modification additives are structure-forming; they disperse or create their own structure in the bitumen. The polymer frame limits, on the one hand, flowing at higher temperaturesRead More

The use of bitumen emulsion has several benefits compared to regular bitumen binding materials: the viscosity of bitumen emulsions at room temperature is several times less than that of straight bitumen, facilitating easy permeation even small pores of the treated surface; emulsion higher adhesion to various surfaces, making it possible to create stronger road layers;Read More

Oil-based road construction bitumen is the main binding substance used in construction and repair of roads; it is elastic, can withstand low temperatures and temperature deviations without breaking, and resists deformations. However, specific operation of high load objects such as bridges, overpasses etc require higher quality of asphalt pavements. Normal bitumen cannot entirely meet theseRead More

In reality, diesel fuel almost always contains water and other impurities. Since regular filters cannot capture water, and separator filters don’t always work as advertised, water contamination remains the biggest concern. The lifetime of a fuel system in a vehicle depends on the quality of the diesel fuel (mostly its purity). When the tank isRead More

In the process of emulsification, bitumen is dispersed into microscopic particles, while internal cohesion and viscosity of bitumen, as well as interfacial tension resist the formation of new phase boundary surface. Bitumen particles tend to coalesce. To make a stable emulsion, it is necessary not only to apply mechanical forces correctly to make small enoughRead More

Bitumen emulsions dispersed systems which consists mainly of bitumen and water, in which one liquid is dispersed in the other in the form of small droplets. The breaking (dispersion) of bitumen in water is usually done in colloid mills, also referred to as homogenizers or dispersers. Regardless of the actual design of the equipment, theRead More

Bitumen emulsions have found wide use recently in construction and road repairs. Straight bitumen has long been the only binding material, but with the emergence of bitumen emulsion, the situation started to change, because emulsion have several apparent benefits compared to the traditional binding material, including: savings on heating; no harmful emissions into the environment;Read More

Bitumen emulsions are successfully applied in construction of pavements with various mineral aggregates by mixing on the road and impregnation surface treatment (single or double) and also by making black top with mineral aggregate made by mixing the aggregate with emulsions.
