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.
