Technical performance and benefits of recycling of reclaimed asphalt containing polymer modified binder into premium surface layers

The technical possibilities and the benefits when recycling polymer modified asphalt from surface layers into new high quality surface layers using hot mix recycling are investigated. First rheological properties are determined of blended binders, consisting of extracted binders from reclaimed asphalt containing polymer modification and virgin binders. The performance of asphalt mixtures containing reclaimed asphalt with polymer modified is tested with respect to water resistance, stiffness, rutting and fatigue. The economic and ecological effects are evaluated using LCA and LCC. It has been demonstrated that the polymer present in the reclaimed asphalt still positively affects the material behaviour of asphalt mixes produced with this material. LCA and LCC analyses clearly demonstrate the environmental and economic benefits. Based on these positive results validation in practise is the next logical step.
