“…Case studies by Huang et al reported that the use of 25% RAP and 10% of fly ash contributed to a 4% reduction in total energy consumed for the production and layout of the mix as well as CO2 emissions [9]. Another study by Aurangzeb et al found that the use of 30%, 40%, and 50% of RAPs decreased energy and CO2 consumption by 7.3%, 9.8% and 12.2%, respectively, compared to the situation where the PAP was not used [10]. Finally, a recent study by the US Environmental Protection Agency (US EPA) reported that using 25% of RAPs reduced greenhouse gas emissions by up to 16%, highlighting the importance of use of recycled materials.…”

RezumatO problemă actuală a economiei mondiale o constituie atât gestionarea responsabilă a resurselor neregenerabile ale planetei cât și gestionarea numeroaselor deșeuri rezultate în urma a diverse activități economice. Beneficiile aduse de utilizarea materialelor reciclabile împreună cu tehnologiile de reciclare a mixturilor asfaltice constau în principal în reducerea consumului de combustibil și a emisiilor de gaze cu efect de seră. Este un lucru bine știut că petrolul (din care se obține bitumul) este o resursă neregenerabilă, de unde și prețul său tot mai ridicat. De aceea, la ora actuală, pe plan mondial se caută soluții care să conducă la o buna utilizare a resurselor naturale, dar și de integrare în circuitul economic al unor subproduse din diverse industrii. Această lucrare dorește să aducă în prim plan soluțiile de reciclare a mixturilor asfaltice, precum și materialele reciclabile care pot fi folosite ca adaosuri, împreună cu beneficiile fiecăruia.Cuvinte cheie: reciclare, încălzire globală, zgură, pudreta de cauciuc, plastic Abstract A current worldwide economy problem includes both the responsible management of the planet's non-renewable resources and the waste management. The benefits of using recyclable materials and recycling technologies with asphalt mixtures consist mainly of reducing fuel consumption and greenhouse gas emissions. It is well known that oil (from which bitumen is obtained) is a non-renewable resource, hence the its price increase. Therefore, at present, the world is looking for solutions that will lead to a better use of natural resources and to an economic integration of sub-products from various industries. This paper intends to raise awareness of the possibilities for asphalt mixtures recycling and of the recyclable materials that can be used as additives with benefits of each.

“…Aurangzeb et al (2014) examined the environmental footprint of asphalt mixtures prepared with high RAP content. The authors observed reductions in energy and GHGs of up to 12.2% with mixtures prepared with 50% recycled RAP material.…”

“…At some point, the extra fuel will offset any environmental or energy savings from the material production phase. The level of pavement performance at which this occurs can be represented by a "breakeven" service life, as first used by Aurangzeb et al (2014). It should be noted that the breakeven service life can also be greater than 15 years if the performance of the evaluated overlay is better than the baseline overlay performance as predicted in the IRI progression model.…”
