Replacement of bitumen in asphalt

Abstract

The main purpose of this article is to study the technology that represents a better solution to convert asphalt into modified greener, cheaper and more sustainable pavement. Not only in Finland, but also in the world, most of the roads are covered with asphalt (including bitumen as a binder), so the future is for substitutes that can replace bitumen. My goal is to map re-placement technologies on a global scale and introduce circulation technologies to evaluate all the economic and technological advantages and disadvantages. It is also necessary to answer the question why we must always replace the bitumen. To provide a more correct description, it should be compared with new technologies from representatives all over the world. In this topic is very interested the Street Maintenance and Construction Department of the city of Lahti. It is my commissioner and they are very interested in environmental friendly, sustainable replacement solutions.
