ARIAsphalt® Bitumen Emulsion is a specially formulated bitumen-based emulsion developed for modern road construction, pavement maintenance and infrastructure applications. It consists of finely dispersed bitumen particles suspended in water with the aid of suitable emulsifying agents, allowing bitumen to be handled and applied at significantly lower temperatures than conventional hot-applied bitumen.
Bitumen emulsion provides an efficient and practical solution for road construction because it can be applied without the need to heat conventional bitumen to very high temperatures. This can simplify handling, improve application safety and support more efficient road construction and maintenance operations.
ARIAsphalt® promotes its Bitumen Emulsion as a solution for prime coats, tack coats and surface dressing, highlighting ease of application, reliability, non-flammability and sustainability-related advantages.
Bitumen emulsion is essentially a dispersion of very small bitumen droplets throughout a continuous water phase.
Bitumen + Water + Emulsifying System
The emulsifying system keeps the bitumen particles dispersed in water and allows the product to remain sufficiently stable during storage, transportation and application.
After application to a road or pavement surface, the emulsion undergoes a process commonly referred to as breaking or setting. During this process, the dispersed bitumen droplets come together and the water phase separates or evaporates, leaving a continuous bituminous film on the treated surface.
The exact formulation, bitumen content, viscosity, setting characteristics and performance depend on the specific ARIAsphalt® emulsion grade selected for the project.
ARIAsphalt® Bitumen Emulsion offers several important advantages for road construction and maintenance:
ARIA specifically describes its Bitumen Emulsion as easy to apply, eco-friendly, reliable and non-flammable, with applications including prime coats, tack coats and surface dressing.
The performance of ARIAsphalt® Bitumen Emulsion is based on the controlled dispersion and subsequent breaking of bitumen particles.
When the emulsion is applied to an aggregate or pavement surface, the water phase gradually separates from the bitumen. Depending on the formulation and environmental conditions, the emulsion breaks and deposits a continuous bituminous film over the treated surface.
This bituminous film provides adhesion, waterproofing characteristics and binding action.
In a tack coat, the residual bitumen helps bond an existing pavement layer to a newly placed asphalt layer.
In a prime coat, the emulsion penetrates and treats a suitable granular base, helping prepare the surface for subsequent bituminous pavement layers.
In surface dressing, the emulsion binds aggregate particles to the pavement surface, creating a protective and durable surface treatment.
ARIAsphalt® Bitumen Emulsion can be used as a prime coat on suitable granular road bases before the application of subsequent bituminous layers.
The prime coat helps:
The actual emulsion grade and application rate should be selected according to the pavement design and project specification.
Tack coating is one of the most important applications of bitumen emulsion.
A tack coat is applied between existing and new bituminous layers to improve interlayer bonding.
ARIAsphalt® Bitumen Emulsion can help provide:
Proper surface cleaning and controlled application are essential for achieving effective tack coat performance.
Bitumen emulsion is widely used in surface dressing applications where bituminous binder is applied to a prepared pavement surface and aggregate is subsequently spread and compacted.
The binder holds the aggregate in position and creates a protective surface layer.
Surface dressing can help:
ARIAsphalt® Bitumen Emulsion can be used in a variety of road maintenance and pavement treatment operations.
Potential applications include:
Its liquid form makes it particularly useful where controlled and uniform application is required.
One of the major advantages of bitumen emulsion is that it can generally be applied without heating the binder to the high temperatures required for conventional hot bitumen.
This can reduce heating requirements and simplify field operations.
ARIAsphalt® Bitumen Emulsion is supplied as a liquid product, allowing it to be transported, stored and applied using suitable liquid-emulsion handling equipment.
Because the product does not require the same high-temperature application process as hot bitumen, it can reduce risks associated with handling extremely hot binder.
ARIA also promotes its Bitumen Emulsion as non-flammable during normal handling.
A suitable bitumen emulsion grade can be used for:
The reduced need for high-temperature heating can potentially lower energy consumption associated with bitumen application.
Because bitumen emulsion is available in different grades and setting characteristics, technical values such as bitumen residue, viscosity, setting time and particle charge should be confirmed from the specific ARIAsphalt® grade TDS supplied for the project.

Important: Bitumen emulsion is not a single universal specification. Cationic, anionic, rapid-setting, medium-setting, slow-setting and polymer-modified emulsions have different properties. Therefore, the exact technical values should not be assumed without identifying the specific ARIAsphalt® grade.
The application method depends on whether the product is being used as a prime coat, tack coat or surface dressing.
Application rates should always be established according to the specific grade, pavement condition, aggregate characteristics, weather and project specification.
Proper surface preparation is critical for good bitumen emulsion performance.
The surface should be:
Poor surface preparation can reduce adhesion and lead to premature failure of the treated pavement.
Bitumen emulsion performance can be influenced by environmental conditions.
Application should generally be avoided during unsuitable weather conditions such as heavy rain or when the pavement temperature and moisture conditions are outside the manufacturer’s specified range.
Temperature, humidity, wind and surface moisture can influence the rate at which the emulsion breaks and cures.
Therefore, project-specific application conditions should always be checked before spraying.
ARIAsphalt® Bitumen Emulsion should be stored and handled according to the manufacturer’s recommendations for the specific grade.
General storage practices include:
Different emulsion grades may have different storage requirements, so the relevant technical documentation should always be followed.
Although bitumen emulsion is generally easier and safer to handle than hot-applied bitumen, normal industrial precautions should still be followed.
Bitumen emulsions can offer environmental and operational advantages compared with conventional hot bitumen because they generally require less heating during application.
ARIAsphalt promotes its Bitumen Emulsion as an eco-friendly road construction solution and highlights reduced reliance on high-temperature application.
Nevertheless, responsible storage, spill prevention, waste management and disposal practices should always be followed in accordance with applicable environmental regulations.
ARIAsphalt® Bitumen Emulsion is designed to provide a practical binder solution for modern road construction and pavement maintenance. Its liquid form, ease of application and suitability for prime coats, tack coats and surface dressing make it a versatile material for road contractors and infrastructure developers.
ARIA’s published information also indicates investment in laboratory and pilot-plant capabilities for testing bitumen and producing smaller batches of polymer-modified bitumen and bitumen emulsions for research and development.
