Yurop i gat ol strongpela lo bilong 'asphalt' na sistem bilong 'recycling' we i gutpela tru. Dispela atikol i glasim hau ol i save yusim 'asphalt rejuvenation' aninit long ol standet bilong Yurop.
Yurop i gat nambawan sistem bilong risaikel kolta long wol. European Asphalt Pavement Association (EAPA) i tok, Yurop i save kamapim samting olsem 70 milien ton bilong RAP long olgeta yia, na moa long 80% bilong en ol i save yusim gen. Long Jemani, Frans, Netelan, na ol kantri bilong Nodik, RAP konten insait long 'hot-mix' risaikel i save kamap long 30-50%, na long 'warm-mix' risaikel inap long kamap 50-80%. Long kamapim dispela bikpela mak bilong risaikel i stap long tripela samting: namba wan, wanpela gutpela RAP gred stoa sistem — ol miksing plent bilong Yurop i save lukautim ol RAP greding warehaus, na ol i save tilim RAP i go long planti gred long 'bitumen content' na 'aggregate grading'; namba tu, ol gutpela teknikel standet bilong risaikel — Yuropian Standet EN 13108 series i putim ol klia teknikel rikwaemen bilong ol risaikel kolta miks; namba tri, ol polisi bilong pasim kabon — EU Emissions Trading System (EU ETS) na ol nesenel kabon takis i givim stretpela ekonomik veliu long 30% emisen ridaksen bilong 'warm-mix recycling'.
EN 13108 series em i wanpela bilong ol bikpela 'asphalt mixture' standet sistem long wol, wantaim EN 13108-20 we i makim stret ol teknikel rikwaemen bilong ol 'asphalt mixture' we i gat ol samting we ol i bin yusim gen. Ol bikpela tok i gat: namba wan, greding na karakterisasen bilong ol RAP materiel — i nidim ful tes bilong RAP long luksave long 'bitumen content', 'aggregate greding', 'bitumen performance', na 'aggregate performance'; namba tu, skelim bilong ol 'rejuvenator' - we i nidim ol 'physical' na 'chemical' paramita bilong 'rejuvenator' na ol data bilong skelim wok bilong 'regeneration'; namba tri, ol samting we ol i mas mekim long ol 'recycled mixtures' — olsem 'Marshall stability', 'air voids', 'water sensitivity', na 'fatigue performance'; namba foa, kontrol bilong prodaksen — we i nidim wok bilong sekim gutpela bilong ol samting ol i wokim gen long taim bilong prodaksen. Long ol saplaia we i no bilong Yurop, bikpela samting long go insait long maket bilong Yurop em long soim olsem 'rejuvenator' bilong ol i inapim ol 'assessment requirements' bilong EN standet. Ol i wokim dispela 'rejuvenator' bilong FangService wantaim tingting long ol EN standet - 'viscosity' bilong 280 mPa·s (Brookfield long 135°C), 'flash point' bilong 231°C, 'post-RTFOT' 'viscosity ratio' bilong 1.1, na 'post-RTFOT' 'mass change' bilong 0.9% - olgeta i stap insait long ol mak we maket bilong Yurop i laikim.
Yuropian RAP greding sistem em i as tru bilong gutpela wok bilong risaikel. Insait long European model, RAP em i no 'wanpela hip bilong olpela samting' tasol em i wanpela enjiniaring samting we ol i mas skelim na luksave long en bihainim ol pasin we i stap pinis. Wok bilong gredim ol samting i save inkludim: namba wan, kisim ol sempel — kisim ol sempel long olgeta taim long wanwan seksen bilong milim; namba tu, tes — mekim wanpela ful suit bilong ol tes long ol sempel bilong luksave long 'bitumen content' (ignition method), 'aggregate grading' (sieve analysis), 'bitumen performance' (penetration, softening point, viscosity), na 'aggregate performance' (crush value, abrasion, water absorption); namba tri, greding — brukim RAP i go long sampela gret bihainim 'bitumen content' na 'aggregate grading range' (olsem, Jemani i save brukim i go long tripela gred: 0-5%, 5-7%, na 7%+ 'bitumen content'); namba foa, stoa — putim na putim nem long wanwan gret seperet long stopim ol samting long miks. Dispela greding sistem i givim wanpela gutpela data faundesen bilong risaikel miks miks disain, na long dispela rot i mekim gutpela wok bilong kontrolim kwaliti bilong risaikel pevemen. Long ol kantri we i no bilong Yurop, kamapim wankain RAP greding sistem em i wanpela gutpela rot long apim mak bilong yusim ol samting bilong risaikel.
Insait long wok enjiniaring bilong ol rot long Yurop, gutpela bilong 'warm-mix recycling' i no stap tasol long teknikel pefomens tasol moa yet long ekonomik konvesen bilong kabon emisen. EU Emissions Trading System (EU ETS) nau i gat prais bilong kabon we i stap klostu long 60-80 yuro long wan wan tan bilong CO2, na wok bilong risaikel long 'warm-mix' i save daunim 'fuel consumption' na ol CO2 emisen long 30% taim yumi skelim wantaim 'hot mix'. Long wanpela 100,000-ton pevemen projek, 30% daunim bilong 'emission' i wankain olsem 3,000 ton bilong CO2, we i gat pe bilong 180,000-240,000 yuro long prais bilong kabon nau. Na tu, sampela kantri bilong Yurop (olsem Jemani na Netelan) i save putim takis long kabon long ol rot enjiniaring, na daunim bilong ol 'emission' we i kamap long 'warm-mix recycling' i save daunim hevi bilong takis. Insait long dispela polisi envairomen, ekonomik keis bilong 'warm-mix recycling' i no moa wanpela implisit benefit olsem 'fuel savings' tasol em i wanpela 显性 benefit — kabon kredit reveniu na kabon takis abrusim — we ol i ken kaunim stret long projek fainens.
Insait long wanpela projek bilong stretim haiwe (Bundesstraße) bilong Jemani, enjiniaring dipatmen i adoptim wanpela 'warm-mix recycling' solusen wantaim 65% RAP konten. Ol bikpela data: namba wan, RAP i kam long 'asphalt surfacing' we ol i bin putim 20 yia i go pinis, na bihain long ol i bin gredim, ol i yusim 5-7% gret RAP; namba tu, 'rejuvenator dose' em 12% bilong 'bitumen mass' insait long RAP, na 'post-rejuvenation penetration' i kamap gut gen long 22 dmm i go long 48 dmm (virgin bitumen em 52 dmm); namba tri, tempereja bilong miksim i go daun long 180°C i go long 130°C, na i sevim samting olsem 35 MJ bilong fiul long wan wan tan bilong miks; namba foa, projek i kisim 'low-carbon highway' setifikesen long German Federal Environment Agency, wantaim 'carbon credit revenue' bilong samting olsem 150,000 yuro. Bikpela samting bilong dispela keis em olsem em i soim olsem aninit long hai-standet reguletori sistem bilong Yurop, hai-AP rijeneresen i no inap long kamap long sait bilong teknikel tasol tu em i gutpela moa long sait bilong ekonomi winim ol konvensenel hot-miks solusen — taim ol i tingim mani bilong kabon kredit i go insait long projek fainens, komprehensif kos i 30-40% daunbilo long ol konvensenel hot-miks.
Long ol saplaia bilong 'asphalt rejuvenator' we i laik go insait long maket bilong Yurop, rot bilong bihainim lo i nidim gutpela plening. Pastaim, redim ol teknikel pepa — bungim olgeta teknikel pepa bihainim ol EN standet, wantaim ol fisikel na kemikel paramita, ol data bilong skelim gut wok bilong kamapim gen, na wanpela sefti data pepa (SDS). Namba tu, namba tri pati setifikesen — mekim rejuvenator i kisim tes na setifikesen long wanpela leboretori we i gat tok orait long Yurop. Namba tri, pailot projek — pinisim wanpela pailot projek wantaim ol poroman bilong Yurop long bungim ol lokol enjiniaring data. Namba foa, longpela taim wok bung — kamapim wok bung wantaim ol lokol miksing stesin opereta o ol enjiniaring kampani long givim teknikel sapot na saplai asurens oltaim. Bihain long dispela 4-pela step, saplaia bilong 'rejuvenator' i inap long insait long pablik bid long maket bilong Yurop. Bikpela tingting em: banis bilong go insait long maket bilong Yurop i antap, tasol taim ol i go insait, mak bilong maket na kwaliti bilong projek i antap tru winim ol diveloping rijen.
