The reach of Indian roads has extended to vast areas of different states and many rural areas. The connectivity of areas has significantly improved leading to more substantial economic development over the years. With better access to technology, consequently greater awareness alternatives were discovered in road infrastructure planning.
Crumb Rubber Modified Bitumen (CRMB) is a binding agent used by many contractors as it increases the strength and durability of roads. Today different CRMB suppliers in India are using different modifiers with their bitumen to enhance the quality of their products. CRMB is a hydrocarbon Binder derived from scrapped rubber from used tyres and treated with chemicals to act as a modifier for Bitumen. To keep the properties of binder intact through all stages of the supply chain, stabilizing additives are also used in the process.
Crumb Rubber Modified Bitumen conforms to IS:15462 specifications and licensed by Bureau of Indian Standards.

The government is paying special attention to improving infrastructure of roads and encouraging research and development for instilling better technologies in their urban planning. The available resources also encourage more industry experts actively contributing to the process.
Every one of us is aware of the deteriorating road conditions in rural areas in India. A predominant technology used in the construction of roads in India has been HMA or Hot Mix Asphalt. Using bitumen emulsified pavements the entire network of roads was made conventionally. However, there are numerous limitations in using HMA. The use of hot mix asphalt leads to high greenhouse gas emissions and other related problems. During the monsoons, this kind of hot mix technology becomes a challenge since a lot of money and effort is spent in maintaining the pavement temperatures. Numerous rural road projects in India hence is now being redefined with the invention of new products like cold mix bitumen emulsions.
A huge number of rural areas in India which is located mostly in its North and Northeastern regions witness heavy rainfalls and is extremely mountainous terrains. The environmental regulations in these sites are complex and most of the projects even fall within forests. Using traditional hot mix technology sometimes is just not possible. Cold mix asphalt, on the other hand, is being evaluated to be used in such scenarios. Cold mix bitumen emulsion in India has numerous advantages like it offers to reduce GHG emissions, reduced fuel consumption and ease of use in all seasons.
Cold mix bitumen emulsion in India erases off the heating procedure used in the binder and the aggregate. Moreover, it is extremely eco-friendly in nature. Over 50% of energy spent on hot mixes can be saved if cold mix bitumen is used. The preparation time for a cold mix is much lesser and can be made right on the sites. The cold mix bitumen emulsion is applicable to be used even in remote locations in India. This can also be used in humid and wet weather conditions. In addition to the above, the cold mix technology is much more economical and high on productivity and profitability. The cold mix bitumen emulsion has been innovated by keeping the differentiated requirement of the Indian terrain and nation.
By far, Bitumen emulsion is most commonly used a binding agent for construction of roads. It acts as adhesive, waterproofing agent, preservative, binder etc. But they have one special class or you can say an improvised version of the same, which is called polymer modified bitumen emulsion. Polymer modified bitumen emulsion manufacturers, prepare it in several ways. One way for the same is by adding latex to bitumen emulsion. It can be done both prior and after the colloid mill. PMB emulsion suppliers in India, find it difficult and hard to manufacture this special class of bitumen emulsions. The characteristics of both types of emulsions are almost same but PMBE’s generally have high performance and act as better binding agent as compared to the unmodified version of bitumen emulsions.
The difference only lies in the rheological properties of the same, PMBE’s have better and improvised rheological properties as compared to the unmodified version. There are two types of modifying agents that are being used by PMB emulsion suppliers in India. The first one is Plastomers and the other one is Elastomers.
- Plastomers, have good properties with respect to high temperatures and are low in cost. They also have resistance towards rutting and has good storage stability. The disadvantage of plastomers is that it has limited elasticity and has phase separation issues. Also, it has a relatively low performance at low temperature.
- Elastomers, on the other hand, has increased stiffness, has better elasticity and works better even at low temperature. It also has resistance towards ultraviolet and oxidation. The disadvantage of the same is that it is relatively high in cost, and relatively less compatible with some of the bitumen emulsions.
The benefits of Polymer modified bitumen emulsion as compared to the unmodified version are:
- They have increased elastic recovery that ensures protection in extreme cold climatic conditions.
- Acts as a better binding agent to aggregate as its adhesive property improve.
- By modifying bitumen emulsion, Polymer modified bitumen emulsion suppliers in India makes sure that its softening point increases and brittleness fall down. It helps in protection against hot weather conditions.
- Though bitumen emulsions are also water resistant, PMBE’s have increased water resistance property.
- It resists cracking and stripping in low temperature.
- Helps in avoiding rutting and fatigue.
Cold mix is a bituminous mixture which contains mineral aggregate, water and binder (custom designed cationic bitumen emulsion) geared up by a suitable appliance like a concrete mixer or cold mix plant or a customized hot mix plant.
Cold Mix is Cost Effective
Cold Mix Technology is cost effective as well as environment-friendly due to the fact that building work can go on in all seasons and still with wet aggregates. Due to topographical constraints, rural roads projects in the North Eastern States of India like Arunachal Pradesh, Assam, Manipur, Meghalaya, Sikkim, and others have got postponed. Use of Cold Mix Technology is established to be the most suitable one in these states. The biggest benefit of the technology is that it saves on an average just about 1500L of precious fossil fuel per kilometer of road construction. Cold mix pavement can offer energy savings of over 50% as compared with hot mix. So it can be well thought-out as a green technology for infrastructure Projects. Cold mix is gaining a great amount of popularity in road projects and more than 4000km job finished in North-East by cold mix technology.
Cold Mix has Reasonable Viscosity
Cold Mix is in particular designed water-based bitumen emulsion with reasonable viscosity and optimized setting time for mixing stability with an extensive variety of graded aggregate. Cold Mix grade is put together to mix properly with open-graded as well as dense graded aggregate. Cold Mix is recommended for premix carpeting as well as premix seal coat applications due to its high binder content and reasonable viscosity and is manufactured strictly as per IS 8887: 2004. Cold mix is in Chocolate brown in color and is a free-flowing liquid at ambient temperature
Preparation of the mixture
The cold mixed open graded premix can be prepared in a concrete mixer. For this purpose, the blended aggregates of 13.2mm and 11.2mm size in 2:1 ratio should be put together into a concrete mixer.
Thus Cold Mix Bitumen Emulsion in India is highly suitable for some regions which face problems related to topography. It helps in perfect construction process without any issues.
Bitumen emulsion is as important to roads as tyres are to cars. Bitumen and roads go hand in hand. Bitumen is what makes the roads fit to drive on and walk on. Without bitumen emulsion spread on roads the roads of the world would just be uneven debris which would make driving or walking on them extremely difficult. Bitumen emulsion is nothing but a mixture of water and bitumen along with emulsion so that the bitumen does on float on water but mixes with it. There are various types of bitumen, one of them being polymer modified bitumen which is the most strongest and most durable bitumen used on roads and house roofs along with setting time and surface time bitumen who work exactly as their name suggest.
In recent years, the demand for bitumen emulsion in India has risen to such an extent that many bitumen emulsion exporters in India have popped up all around the country. These companies with their experienced man power and hi-tech transport facilities help in exporting bitumen needed by countries all around the world. The exporters make sure that they meet all the increasing demands regarding bitumen as fast as possible. Their main aim is to satisfy their customers and meet their needs.
But apart from just supplying emulsion to construction workers worldwide the bitumen emulsion exporters in India are also responsible about making sure that the need of emulsion put before them are genuine.
