Synthetic Binders from Recycled Polymers as a New Resource

Synthetic Binders from Recycled Polymers as a New Resource 

Recycled materials, such as recycled polyolefin, have been widely employed as bitumen modifiers with exceptional results. In fact, recycled polymers will be one of the main components of synthetic binders in the near future, as discussed later in the chapter. From an environmental point of view, the addition of recycled polypropylene is an alternative option to other more destructive techniques which cause pollution, such as incineration, in order to reduce the waste disposal problem. So, the manufacturing of synthetic binders from recycled polymers, as well as other industrial processes that use waste as raw materials, is the way forward in order to decrease the use of the planet s finite resources. 

The appearance of black roads with white lines is suitable for the purpose of detailing several areas of the road. Despite this fact, in some situations the colour of traditional bitumen is not suitable due to security or aesthetic reasons. The most common causes for modifying the colour of synthetic binders are to  

Most road surfaces are produced using a blend called asphalt, which is composed 

The components of the synthetic binders can be transparent or opaque, virgin or recycled. These different properties improve the technical versatility of these materials. In addition, synthetic binders can be used to modify other characteristics, such as colour or properties of environmental interest, when recycled materials are employed.
