Abstract

Technological innovation is continuously present in the domain of highway engineering. The development of new technological ideas and the elaboration of new methods of construction have resulted in hgh-performance highways and motorways in Europe, in America and elsewhere. It is, nevertheless, well known that innovative materials in highway engineering are produced through long processing methods requiring energy consumption and enhancing the concentration of pollutants in the air. In this way, the sustainability of many methods and materials of technological innovation is questionable. On the other hand, most developed and developing countries stockpile industrial by-products and other waste materials, which generally, present poor engineering properties and are rarely considered suitable for alternative method of construction
