ABSTRACT
The large number of kilometres of asphalt roads throughout the world represent a great consumption of resources in terms of not only the construction of new pavements but also the preservation and renovation of the existing ones. In this sense, the EU policy establishes as a priority target the optimal use of natural resources, the support to innovations that boost cost-effectiveness and the reduction and reuse of waste. The ALTERPAVE project (Use of end-of-life materials, waste and ALTERnative binders as useful raw materials for PAVEments construction and rehabilitation) is aimed at maximizing the amount of Reclaimed Asphalt Pavement (RAP) and several by-products such as slags and foundry sands in the design of asphalt mixtures. Furthermore, a spatial decision support tool will be developed to optimize the supply of these combinations of alternative materials according to not only their functional response, but also including economic, environmental and energy concerns.
