Tropikel klaimet bilong Saut-is Esia i save kamapim sampela bikpela salens long wokim ol 'asphalt pavement'. Dispela atikol i glasim hau 'asphalt rejuvenation' i save mekim 'pavement' i stap longpela taim aninit long ol dispela kondisen.
Tropikel klaimet bilong Saut-is Esia — tempereja bilong 25-30°C long wanwan yia, ren i save pundaun long 1,500-3,000 mm long wanwan yia, na 75-90% we i gat planti wara — na dispela i kamapim sampela bikpela salens long wokim ol 'asphalt pevement' long wol. Dispela tripela salens i kamap olsem. Namba wan, hat i stap oltaim - kolta pevemen tempereja inap long 60-70°C long taim bilong san, antap tru long mak bilong 'bitumen' i kamap malumalum, na dispela i save kamapim 'rutting' - 'longitudinal grooved deformation' - aninit long bikpela trafik. Namba tu, bikpela ren - ol strongpela sotpela taim bilong ren (planti siti long Saut-is Esia i ken kisim 50-100 mm ren long wan wan aua) i save kamapim ol liklik hul wara long rot, na wara i save go insait long 'bitumen-aggregate interface' aninit long lod, na dispela i save kamapim bagarap long wara - olsem ol hul, 'stripping', na 'aggregate loss'. Namba tri, bikpela humiditi na UV rediesen — bikpela tempereja na humiditi i save mekim 'oxidative aging' bilong 'bitumen' i go hariap, na bikpela 'tropical radiation' i save promotim moa yet 'photo-oxidative degradation' bilong ol lait hap insait long 'bitumen'. Dispela tripela salens wantaim i min olsem laip bilong disain bilong 'asphalt pavement' long Saut-is Esia em i 60-70% tasol bilong ol ples we i gat hatpela san, tasol baset bilong mentenens i save liklik.
Rutting em i wanpela hevi we i save kamap planti taim na i save givim bikpela hevi long ekonomi long ol 'asphalt pavements' long Saut-is Esia. Aninit long hat i stap longpela taim, 'bitumen viscosity' i go daun na 'pavement' i save kisim 'plastic deformation' taim ol i save putim planti kar (ol trak, bas), na dispela i save kamapim ol 'longitudinal depressions' long ol rot bilong ol wil. Ol hevi bilong 'rutting' i gat planti samting: namba wan, sefti - taim 'rut dip' i winim 15 mm, ol kar i ken tanim o lusim kontrol long bikpela spit; namba tu, 'drainage' i no wok gut - wara i bung long ol 'rut' i save mekim 'hydroplaning' i go antap long taim bilong ren; namba tri, bagarap long straksa — plastik i save senis oltaim na dispela i save mekim 'fatigue failure' bilong 'base course' i go hariap. Pasin bilong bipo em long yusim 'high-viscosity' o 'modified bitumen' (olsem SBS 'modified bitumen'), tasol tupela rot i save mekim pe bilong ol samting i go antap. Dispela 'rejuvenator' bilong FangService, long rot bilong 'modifikesen' wok insait long 3-in-1 sistem bilong en, i kamapim wanpela tripela-daimensenel kros-link netwok bihain long 'regeneration', na i save apim 'elastic recovery' bilong 'rejuvenated bitumen' i go antap long 85% bilong 'virgin bitumen' taim em i holim liklik miksing tempereja. Dispela i min olsem aninit long ol hatpela kondisen bilong Saut-is Esia, strong bilong 'rutting' bilong 'rejuvenated asphalt mixture' i no liklik long 'conventional hot-mix' miks, tasol pe bilong en i daunbilo long 25-40%.
Bagarap bilong wara em i namba tu bikpela hevi long ol 'asphalt pavements' long Saut-is Esia, na divelopmen bilong en em i wanpela 'chain reaction'. Step wan, wara i go insait — aninit long bikpela ren, wara bilong raunwara i save go insait long 'pavement structure' long rot bilong ol 'air voids' bilong 'asphalt mixture' (planti taim 4-6 pesen). Step tu, 'interface debonding' - aninit long lod, wara i kamapim 'hydrostatic pressure' long 'bitumen-aggregate interface', na i save bagarapim 'bond' namel long 'bitumen film' na 'aggregate surface'. Step namba tri, agreget lus — bihain long bond i bagarap, ol agreget patikel i save go aut long ol wil lod, na kamapim ol hul. Step namba foa, hul i go bikpela — wara insait long ol hul i bagarapim moa yet ol rot i stap klostu, na kamapim ol bikpela hap we i gat hevi. Dispela 'rejuvenator' bilong FangService i strongim 'bond' long 'bitumen-aggregate interface' long rot bilong 'three-dimensional cross-linked network', na i save daunim tru bagarap bilong wara. Ol data we ol i skelim i soim olsem strong bilong 'rejuvenated asphalt mixture' (strong bihain long 7-pela de wara imersen vs. drai strong) em i 15-20% antap long 'conventional hot-mix' miks.
Ol kantri long Saut-is Esia i stap long ol narapela narapela step bilong divelopmen bilong RAP risaikel. Namba wan lain — Singapore na Malaysia: wantaim ol gutpela RAP gred stoa sistem na ol teknikel standet bilong risaikel, RAP konten inap long kamap 40-60%. Land Transport Authority (LTA) bilong Singapore i laikim olgeta bikpela haiwe projek long skelim sapos ol rot bilong risaikel i ken kamap. Namba tu lain — Thailand, Vietnam, Indonesia: RAP risaikel i stap tasol greding i no pinis, na risaikel konten i save stap 20-30%. Namba tri lain — Myanmar, Cambodia, Laos: RAP risaikel i klostu zero, wantaim bikpela hevi em i sot long ol ikwipmen bilong sekim na ol teknikel standet. Maski kantri i stap long wanem kain lain, ol i ken yusim 'rejuvenator' bilong FangService stret - 'liquid concentrate', ol i pamim long ol 'additive system' we i stap pinis, na i no nidim wanpela spesel ikwipmen. Long ol kantri we i stap long namba tri lain, dispela i min olsem ol i ken lusim teknoloji evolusen we ol divelop kantri i bin go tru long en - stat long 'dilution oil' i go long 'molecular regeneration' - na adoptim namba tu jeneresen 'molecular regeneration' teknoloji stret.
Insait long wanpela projek bilong stretim 'expressway' long Thailand, dipatmen bilong enjiniaring i kamapim wanpela 60% RAP rijeneresen tes seksen bilong skelim wantaim wanpela konvensenel hot-miks seksen. Ol bikpela data: namba wan, as bilong RAP em i 'asphalt pavement' bilong 15 yia i go pinis, wantaim 'bitumen' konten bilong samting olsem 5.5%, na 'aged bitumen softening point' i bin go antap long 48°C i go long 65°C; namba tu, 'rejuvenator dose' em i 8% bilong RAP 'bitumen mass', na 'post-rejuvenation softening point' i pundaun i go bek long 51°C (insait long 3°C bilong 'virgin bitumen'); namba tri, temperaja bilong miksim i go daun long 180°C i go long 130°C, na i daunim fuel konsumsen long samting olsem 30%; namba foa, bihain long tupela taim bilong ren, hap we ol i bin kamapim gen i gat 40% liklik hul na 30% liklik 'rut depth' winim hap we i gat 'hot-mix'. Bikpela samting bilong dispela keis em olsem em i soim olsem aninit long ol tropikel klaimet kondisen bilong Saut-is Esia, wok bilong stretim kolta i no wok gut tasol insait long leboretori tasol tu em i sanap strong long tupela tes bilong hat na bikpela ren long ol rot tru.
Long ol manmeri i baim ol rot long Saut-is Esia, taim ol i makim 'asphalt rejuvenator' ol i mas tingim gut ol dispela samting. Namba wan, 'high-temperature stability' — 'rejuvenator' yet i no ken pairap o bagarap long bikpela tempereja, na 'flash point' i mas antap inap (rejuvenator long FangService i gat 'flash point' bilong 231°C, antap tru long 'mixing temperature' bilong 130-140°C). Namba tu, wara i no inap bagarapim — ol saplaia i mas givim ol data bilong Marshall tes na 'freeze-thaw split test'. Namba tri, em i ken wok wantaim ol 'modified bitumen' bilong ples — SBS 'modified bitumen' na 'rubberized bitumen' em ol i save yusim planti long ol kantri bilong Saut-is Esia, na 'rejuvenator' i mas inap long wok wantaim ol dispela 'modified bitumen'. Namba foa, saplai stebiliti — ol projek bilong Saut-is Esia i save gat ol tait sediul, na ol lokal inventori na lojistiks kapabiliti bilong saplaia em ol bikpela samting bilong tingim. Namba faiv, teknikel sapot — inap bilong saplaia long givim onsait miks disain helpim na konstraksen gaidens. Long ol projek bilong Saut-is Esia, veliu bilong teknikel sapot long ples i save winim prais bilong prodak yet. View the Asphalt Rejuvenator Supplier
