This report, formally referred to as Deliverable D29 "Guide on Techniques for Recycling in Pavement Structures", is one of the four resulting documents in Work Package 6. It has been developed by CEDEX with the collaboration of EUROVIA and TU Brno and the feedback received from some partners of the consortium. The starting point was the work carried out within Deliverable D5 "Literature Review of Recycling of By-products in Road Construction in Europe". The report includes a guide, structured under the way of technical digests of the most representative waste materials or by-products commonly recycled in road construction (colliery spoil, air cooled blast furnace slag, ground granulated blast furnace slag, steel slag, coal fly ash, coal bottom ash, building demolished by-products, municipal solid waste incinerator bottom ash, scrap tyres, waste glass and foundry sand). Some pavement recycling techniques have not been covered to avoid overlapping with works on the subject by PIARC. Each of the eleven digests of the guide presents similar structured technical information by selected waste or by-products, including origin, recycling (properties of the waste material or by-product; recycling process; properties of the recycled material), uses in road construction, environmental issues, technical standards, specifications or guidelines by country, and technical references
