Technical Performance and Benefits of Recycling of Reclaimed Asphalt Containing Polymer-modified Binder in Premium Surface Layers
bookPart
The technical possibilities and benefits when recycling polymer modified asphalt (PMA) from surface layers into new high-quality surface layers using hot mix recycling are investigated. First rheological properties of blended binders are determined, consisting of virgin binders blended with extracted binders from reclaimed asphalt-containing polymer modification. The performance of asphalt mixtures containing reclaimed asphalt (RA) with polymer modified binder is tested with respect to water resistance, stiffness, rutting and fatigue. The economic and ecological effects are evaluated using lifecycle analyses (LCA) and lifecycle cost (LCC). It has been demonstrated that the polymer present in the RA still positively affects the material behavior of asphalt mixes produced with this material. LCA and LCC analyses clearly show the environmental and economic benefits of recycling of PMA. Based on these positive results, validation in practice is the next logical step.
