Bitumen emulsion centered cold mixing; consist of coating the integral in a industrial bitumen emulsion in water. This emulsion is naturally fluid at ambient temperature, thus no heat is required in the blending, which is a delicate process developed to be sure that the bitumen emulsion does not ‘shatter’ into its constituent elements – bitumen and water – up until it is placed on the pavement.

Professional cold mix plant makes different grades of combination to be plentifully combined together before an adjustable spray bar delivers the binder. Light ‘folding’ then ensures the industrial bitumen emulsion coats the stone without splitting.

The stuff can be utilized for binder layers, overlays and even wearing courses for whatever but the heaviest trafficked roads.

Cold blend asphalt can be placed in precisely the identical manner as hot – directly through a paving machine – but the rolling that follows is particularly necessary to the way the industrial bitumen emulsion works. Specifically developed cold mixture technology based on emulsions and substances (known as NYREC and NYMIX) is compaction with a mix of vibratory and pneumatic-tyred rollers which leads to the industrial Bitumen emulsion to break, delivering the bitumen and enabling the water run out.

In general, a cold combination asphalt layer can be trafficked instantly after placing; however the mixture does proceed to achieve power over time. When laid, it looks and works in a different way from hot mixture – one of the factors the method has not been followed as speedily as it might have done. Cold combination is usually assessed with strategies that are suitable for hot mixes but do not reflect the efficiency of cold mix.

Typical efficiency factors are rigidness and void content, neither of which a real measure of the behavior of a cold mix pavement is layer. Efforts are now being done to resolve this, by putting together a cold mixture design, and techniques of assessment that can become the grounds for future specifications are being developed.

The next significant stumbling block to the uptake of cold mixture is financial. Numerous contractors have huge amounts of money invested in hot mix plants, desire to enhance these investments and find it difficult to contemplate cold mix.

Switching from hot to cold mix could drastically decrease energy bills and CO2 discharges, as the quantity of energy needed to heat the components in cold mix is minute in comparison with hot mix. Typically, only around 0.1 litres of fuel is required to deliver one tonne of cold mixed asphalt compared with between 10 and 14 litres of fuel per tonne of hot mix.

An additional environmental driver for the utilization of cold mix is the need to increase the use of recycled road planings, or Recycled Asphalt Pavements (RAP). Among Nynas’ range of Industrial bitumen emulsion is NYREC, which was designed specifically for use with RAP.

Emulsion-based cold mixes allow a far better proportion of reprocessed substance to be integrated into the mix than is possible with hot mixes. Even a cold mix binder layer can quite productively be made using RAP for the entire aggregate content. Emulsions can also coat planings that are spoiled with tar.

Bitumen industry in India

The first plant for Bitumen in India was introduced in December 2006 at Uluberia, near Kolkata in West Bengal. The industry is changed bitumen and emulsion making plant that develops a variety of special application bituminous products like various grades of Bitumen emulsions, Polymer Modified Bitumen and Crumb Rubber Modified Bitumen. The industry has a total set up volume of 50,000 metric tones per annum which is upgradable.

Furthermore Bitumen in India also supplies ready to use quick road maintenance premix. This makes road to be opened up to traffic within 10-15 minutes and gives good toughness to repaired space. The same is being effectively provided through a system of franchisees in several parts of the country for the last five years and has been pretty well accepted by all contractors, road maintaining agencies and consultants in the country.

Quality Product
The true difference for a client buying item from Bitumen in India rests in basic product expertise, knowledge of its complete chemistry, Quality Control and the technologies around it along with its performance on the ground.  Bitumen in India is more of a remedy provider, delivering customized, fit-for-application and solution of road goods depending on client needs. The company typically works with both the contractor, design and supervision consultant and the owner of airport runways/ major highways and even with rural roads to provide the most appropriate and best product matched to their requirement, product needs and local conditions.

Trade Opportunities for Bitumen in India
India is making a huge network of national highways, state highways and rural roads and would require world-class product to limit the maintenance cost of the roads over their life cycle. There is a large central support, states funding, outside assist from WB / ADB and Private investments to construct this road network. The company can extensively contribute to improve durability of road surface while at the same time reducing maintaining price through the use of technology based methods during pavement development and its protective and regular maintenance .

However previous roads were constructed with the primary objective of moving passenger traffic only, roads nowadays need to deal with extensive movement of goods through heavy load axles on the road on account of explosive economic development.  So the road patterns require to be rightfully upgraded to maintain existing load and traffic depth conditions on the roads.

One more general factor for India is the wide climatic variations over geographies and over various durations.  Additionally, certain sections of the country are subjected to heavy rainfall or heavy snowfall. Further, there is a substantial legacy road network that has poor base and cannot be improved right away but need to be taken care of using maintenance applications. So providing India’s legacy road facilities as well as paving modern Highways and Airports of tomorrow requirements application of High end products and systems.

Bitumen in India enter in the market with two purposes: to influence over 80 years of experience across the world in establishing safe, good quality roads to the benefit of the country and therefore to make a long standing worthwhile business of bitumen in India.
