Bitumen emulsion fundamentally consists of three main components; asphalt, water and emulsifier. Different types of bitumen emulsion are used for different purposes when constructing roads. Depending on the grade manufactured by bitumen emulsion suppliers, the setting time differs. Repairing, maintenance, spraying and constructing are some of the applications of bitumen emulsions. 

Hot Asphalt Applications

Bitumen emulsion suppliers provide bitumen or asphalt and it is used in paving operations generally as a binder It has got adverse environmental effects. Cutback bitumen produces a great amount of greenhouse gas emissions. The greenhouse emission is broadly harmful in two ways; first, it stains the local environment resulting in air pollution and secondly global warming. It is found out that a major portion of greenhouse gas emissions comes from road works associated with hot asphalt applications.

How Bitumen Emulsion Complies With The Environment?

Nowadays, road contractors as well as the government put a lot of effort into incorporating sustainability in road projects as much as they can. As part of the concern for the environment, the bituminous emulsion is used widely with a humble beginning in the 1900s.

When compared to hot asphalt treatments, it offers satisfying performance and supports sustainable development while reducing environmental impact during the process. It is in a liquid form and does not require thermal power before its application. Bitumen emulsion suppliers produce cold and hot type bitumen for varied road use; among them, bitumen emulsion reduces the consumption of intensive energy and hence it is environmentally friendly. 

Bitumen emulsion contributes to sustainable road construction. In some specific road applications, the use of bitumen emulsion guarantees the following:

• No need to use thermal power as it is a cold mix
• Road works become environmental friendly
• Replace cutback bitumen

In particular, the use of bitumen emulsion contributes to a green environment in the following ways:

• It conserves raw materials – Recycling plastic materials along with bitumen emulsion is a new trend followed by many countries like Australia.

• It reduces energy consumption – Risk potential and health adverse effects are less as there is no need to use thermal power. 

In addition to environmental benefits, bitumen also comes with many technical benefits. 

• It is easy to use
• All season friendly
• Better adhesion
• Storable

Bitumen Emulsion 

Bitumen emulsion is one of the abundant products used in road construction. It is used as a surface enrichment property, binder as well as a stabilizer. Every road construction project cannot exclude bitumen emulsion. It contains an emulsifying agent, water and bitumen. The setting time and surface charge contribute to varieties. The bitumen emulsion classification system is specifically designed for the construction of roads and highways. Three types of bitumen emulsion are as follows:

• Rapid setting bitumen emulsion
• Slow setting bitumen emulsion
• Medium setting emulsion

Surface enrichment treatment 

Surface enrichment treatment refers to different techniques used to restore the smoothness of roads. It is generally spraying a layer of bitumen emulsion with aggregate on the top. Bituminous surface treatment is often referred to as a chip seal or seal coat. It is a thin surface treatment using rapid setting bitumen emulsion and other types of bitumen emulsion. The surface treatment is applied on an old roadway or as a cost-efficient rehabilitation solution. Chip seals are applied on rural roads as well as suburban roads with low traffic volume. Clearly formed bitumen emulsions and aggregates are required to achieve desired performance.

Surface treatment is beneficial considering the following advantages:

• Aids in structural deformation of roads
• Inexpensive paving option considering the low volume of traffic
• To seal cracks and provide protection for roads
• Delivers high degree friction and skid resistance
• Resolve minor distresses on the road surface like ravelling and small cracks

Rapid setting bitumen emulsion 

Rapid setting bitumen emulsion is available in two types. Both are designed to set rapidly; one with low viscosity and the latter with high viscosity. Rapid setting bitumen emulsion breaks down within a flick of time as it comes in contact with the aggregate. It clears all lines and scraps on the road. Rough road surfaces need more tack coat application. 

• Bitumen emulsion Rs-1
• Bitumen emulsion Rs-2

In short, bituminous surface enrichment is widely accepted as the best; considering its cost efficiency and rehabilitation capability on roadways. It is especially viable if you have a tight budget but want to apply thin maintenance.

The use of an asphalt tack coat, such as bitumen emulsion rs1, can improve the bond between the pavement layers, increasing the strength of the structure. Under the force of accelerating or decelerating traffic, tack coats can also reduce the tendency for the surface course layer to slide on the underlying layer. Finally, applying a tack coat to the surface course layers can help to prevent top-down cracking.

Tack Coat requirement

Before laying down a new layer of HMA, a tack coat is usually applied to the existing pavement surface. This procedure is followed whether the existing surface is an old asphalt concrete layer or a portland cement concrete (PCC) pavement. In some cases, such as between an HMA surface course and an HMA leveling course, a tack coat is applied to a new HMA pavement layer before the next layer is laid down.

Experts believe that a tack coat is important to protect the new HMA layer from sliding over the existing pavement layer. However, when and to what extent a bond is formed between layers is a hotly debated topic.

However, a variety of factors influence whether or not the tack coat performs as expected. One of these factors is the type of asphalt material used for the tack coat, such as asphalt bitumen emulsion rs1 or asphalt binder. The amount of asphalt binder left on the pavement surface after the tack coat material has “set” is more important than the application rate of the tack coat material, regardless of the type of material used.

Tack Coat application’s impact on the surfacing

On most existing pavement surfaces, the proper amount of residual tack coat material does not cover the entire surface. The tack coat is only applied to 90 to 95 percent of the existing surface in the vast majority of paving situations. 

This means that after the tack coat has been applied, 5 to 10% of the existing surface will still be visible. A lack of tack coat may result in a significant reduction in the pavement structure’s strength and durability. However, too much tack coat can easily form a slip plane between the layers, causing the upper pavement layer to slide on the lower.

When cores are cut soon after HMA pavement layers are installed, it is frequently discovered that there is no bond between the layers. The rate of bond development is influenced by a number of factors, including climatic factors, traffic volume, layer thickness, and the degree of density achieved in the HMA mixture. The existing pavement and the new asphalt layer can take quite a few days to attach well.  In some cases, however, it may take weeks or even months for the bond between two layers to form.

Tack coat is a low-cost coating that improves the bond between pavement layers, increasing pavement strength, reducing surface-course sliding, and reducing top-down cracking. So, Bedrock manufactures an ace quality product called rs1 emulsion. The primary advantage of this emulsion is that drying or setting does not take much time at all.
