In the Zealand road will cost of bio-asphalt

Recently the Dutch research group in the field of food and GE healthcare tissue culture media from Wageningen University announced the development of an innovative material – bio-asphalt on the basis of lignin, which will be used to cover roads in Zeeland (province in the Netherlands).

The new material is the result of two years of the Biobased Infra project, which also involves the Center for the study of asphalt (Asfalt Kennis Centrum) and the company H4A from Sluiskil (NL). Interested have already shown many companies, including Zeeland seaport.

Fossil bitumen – the main 'glue' in asphalt roads – is replaced in the bio-asphalt with lignin, a natural adhesive substance, which is contained in the wood structure of all kinds of plants and trees, and is also one of the main components of wood waste, including straw. The group recently created the first specimens of asphalt concrete based on lignin, and involved the project partners are now engaged in the testing and optimization of its properties.

The bitumen currently used in the asphalt mixtures produced from petroleum, in the process, in which the atmosphere produces large amounts of carbon dioxide. Replacement of bitumen with lignin, according to the researchers, will help significantly reduce the carbon footprint of the production of asphalt. In addition, researchers believe that the use of lignin will improve the functional characteristics of the bio-asphalt, such as rolling resistance and quiet operation.

The Biobased Infra project also includes the design of concrete reinforced with bio-fibers derived from wood waste, cut grass, etc.
