Deliverable D9 is a literature review with special reference to assessment of alternative mate-rials. The aim of D9 is to allow a better knowledge of the state of the art of alternative mate-rial assessment in the perspective of recycling thanks to an analysis of international research. This analysis lays on the knowledge gained and on the development of assessment procedures during the last decade, as well as on recent standardisation progress. These information will serve to design the methodology of assessment in the next step of WP3 (choice of assessment procedures and definition of use-scenarios). This methodology will aim at helping material users by providing recommendations for some of the most important alternative materials in Europe on the best way to characterize them (as stated in Deliverable 4 and aimed also in WP4). This approach may also induce recommendations on the quality to fulfil for some ma-terials, and may therefore have some repercussion on the way to prepare them for use (which can be an output of interest for WP6). This document is divided into three main parts: one dedicated to the state of the art relative to the knowledge of mechanical properties of alterna-tive materials, one dedicated to the state of the art relative to the environmental knowledge on these materials, and a third one dedicated to the issues of the merging of these two approaches today for the development of a general assessment methodology of alternative materials in road construction.
