Dismantling techniques and recycling or other end-of-life treatments of other materials not commonly reused in roads

Abstract

The interest of recycling of waste, industrial by-products and other road materials for pavement construction and rehabilitation has been generally growing in Portugal, for the last 10 years. Among the several types of wastes, there’s been a great interest in using recycled tyres as a raw material to be incorporated in asphalt paving mixtures. The first significant experience with asphalt rubber, manufactured by the wet process, applied on a full scale rehabilitation project, took place in the late 1990’s.
