Waste Rubber from End-of-Life Tires in ‘Lean’ Asphalt ...

Crumb rubber (CR) from end-of-life tires has been used as an additive in asphalt pavements since the 1950s. Two techniques have been worldwide recognized to include CR in asphalt mixtures, namely ‘wet process’ and ‘dry process’ [].Bitumen modified with the ‘wet process’ has been reported to enhance rutting and cracking resistance of asphalt mixtures significantly [2,3,4,5,6,7].
