Bitumen

Bitumen is also known as asphalt. It is a very dark extremely viscous liquid substance. Under normal room temperature, it behaves as almost solid. It is the last remaining chemical to evaporate in the crude petroleum distillation process. It has the highest boiling point of all its chemical components. It also occurs naturally in the earth’s surface such as those found in La Brea Tar Pits in Los Angeles, California.

Asphalt has many industrial uses. Current industrial technologies allow the mixture of bitumen with petroleum solvents or with water to create a bitumen emulsion at room temperature. This is in contrast with the use of hot asphalt in which the asphalt is heated to make it less viscous, and therefore become more tenable for different applications.

 Asphalt Emulsion

Mixing asphalt with water, emulsifiers, and additives using bitumen equipment creates an emulsion. This is extensively used in the road construction industry. Worldwide production of bitumen emulsion is estimated at about 8 million tons.

Asphalt emulsion can either be anionic or cationic depending on the desired affinity for aggregates. They are further classified into grades depending on their reactivity and physical properties. The correct recipe needs to be determined to get the appropriate grade for the specific application.

Bitumen modification

Another technology in use today is bitumen modification. Polymers are used to affect the properties of bitumen. These are called polymer-modified bitumen or PmB. Polymers are complex molecules of long chained hydrocarbons.  Polymers have both stiffness and elastic properties. Bitumen modification is primarily done to lower the temperature dependency and control the oxidation hardening of asphalt or bitumen composites.

Using polymer-modified bitumen in conjunction with new techniques in road construction can increase the performance of modern road systems. Several different performance enhancements can be attained by bitumen modification.

Examples of polymers used for bitumen modification includes the following:

–    styrene-butadiene-styrene
–    synthetic styrene-butadiene-rubber
–    ethylene-vinyl-acetate
–    natural rubber latex
–    atactic polypropylene
–    high molecular weight waxes

Some of the improvements include the following:

–    better consistency
–    lesser temperature vulnerability,
–    improved firmness and solidity
–    greater elasticity and toughness
–    stronger binder-aggregate adhesion
–    decreased dependence on repair and maintenance
–    greater resistance to rutting
