Asphalt chinhu chakasiyana-siyana chekugadzira chinoshandiswa mukugadzira mugwagwa, kugadzirisa, uye kugadzirisa. Inogadzirwa kubva musanganiswa weaggregates, filler, uye bitumen. Asphalt mixing plants (AMP) inoshandiswa kugadzira hot mix asphalt (HMA), inova ndiyo inonyanya kushandiswa mhando yeasphalt inoshandiswa mukugadzira migwagwa. Kune kunyanya maviri marudzi easphalt kusanganisa zvirimwa:
- Batch Asphalt Mixing Plant:Batch asphalt zvinomera zvinoshanda nekusanganisa batch yeasphalt panguva. Saizi yebatch kazhinji iri pakati pe4 ne8 matani. Iyo batch yekusanganisa maitiro inotanga nekudyisa nekuomeswa kweaggregates. Izvo zvakaunganidzwa zvinozoongororwa uye kuyerwa. Iyo bhitumini inopisa uye inoyerwa uye yobva yawedzerwa kumusanganisi pamwe chete neaggregates uye filler. Musanganiswa unosanganiswa kwenguva yakafanotemerwa uye wozoburitswa kubva kumusanganisi.
- Inoenderera mberi Asphalt Mixing Plant:Inoenderera mberi asphalt zvinomera zvinoshanda nekusanganisa rwizi rwunoenderera rweasphalt. Iwo aggregates, bhitumeni, uye filler zvinodyiswa mumusanganisi pamwero wakadzorwa. Musanganiswa unosanganiswa sezvaunofamba nemusanganisi uye wozobudiswa kubva kumusanganisi.
Misiyano yakakosha pakati pebatch uye inoenderera mberi ichisanganisa zvirimwa zvinosanganisira:
- Kukwanisa Kugadzira:Zvidyarwa zvinoramba zvichirimwa kazhinji zvine hukuru hwekugadzira pane batch zvirimwa.
- Kuenderana:Zvidyarwa zvinoenderera zvinogona kupa humwe hunoenderana musanganiswa wemhando nekuda kwekuenderera kusanganisa.
- Kuchinjika:Zvidyarwa zveBatch zvinobvumira shanduko iri nyore resipi uye kubatanidzwa kwehunyanzvi hwekuwedzera.
- Mutengo:Zvidyarwa zvinoenderera zvinogona kudhura kutenga nekushanda, asi zvinopa mari yenguva refu yekuchengetedza kuburikidza nekugadzirwa kwepamusoro uye kugona.
Iwo maviri marudzi easphalt kusanganisa zvidyarwa ane mimwe misiyano yakakosha, asi anotevera yakafanana general kugadzirwa maitiro.
Asphalt Mixing Plant Production Process
- Aggregate Kudyisa uye Kuchengeta: Zvikamu zvinotonhora, kubva pakukura kubva kujecha kusvika kumatombo makuru, zvinounzwa kuchirimwa zvoiswa mumabhini akasiyana. Saizi uye mhando yeaggregate inoshandiswa zvinoenderana neyakagadzirirwa kushandiswa kweyakapedzwa asphalt musanganiswa.
- Kuomesa uye Kupisa: MuBatch Mixing Plants, akaunganidzwa anoiswa mudhiramu rinotenderedzwa nemoto rinodziiswa nembavha. Izvi zvinoomesa uye zvinopisa zvikamu kusvika ku145-160 ° C; MuContinuous Mixing Plants, dhiramu rinotenderedzwa rakafanana kana kuti twunhu tudiki twakaomesa twunoramba twakaomesa uye nekupisa zvakaunganidzwa sezvazvinofambira muchirimwa.
- Kuongorora uye Kupisa Kuchengetedza:Zvinopisa zvakaunganidzwa kubva pakaomeswa zvinozopfuura nepazvivharo zvinodedera kuti zvipatsanure muhukuru hwakasiyana. Aya masaizi aggregates anochengetwa mumabhini anopisa akasiyana kusvika adiwa pakusanganisa.
- Bitumen Heating uye Kuchengeta: Bhitumeni, inosungirira muasphalt, inochengetwa mumatangi anodziya uye inochengetwa inosvika 155-160°C.
- Kuyera uye Kuenzanisa: Pabatch yega yega, pre-programmed ratios of hot aggregates, bhitumeni, uye chero maadiditives angasarudzwa akaita semafirita kana zvinhu zvakadzokororwa zvinoyerwa nekururama kukuru.
- Kusanganisa: MuBatch Mixing Plants zvinhu zvakayerwa zvinoiswa muchigayo chepug, musanganisi mukuru wakachinjika, pazvinonyatso sanganiswa kwenguva yakati; MuKuramba Kuchisanganisa Zvidyarwa, zvinhu zvacho zvinosanganiswa nguva dzose pavanenge vachifamba nemusanganiswa wedhiramu kana pug mill.
- Discharge uye Delivery: Iyo yakapedzwa inopisa asphalt musanganiswa inozoburitswa kubva musanganisi kana chigubhu.
Kuwedzera Maitiro Kusiyana
- Zvishandiso Zvekare:Zvimwe zvirimwa zvinogona kubatanidza chikamu cheyakadzoserwa asphalt pavement (RAP) mumusanganiswa wekuchengetedza uye kuchengetedza mutengo.
- Additives:Zvimwe zvinowedzera zvinogona kushandiswa kuvandudza mashandiro easphalt musanganiswa, senge mapolymers ekuwedzera crack resistance kana ma modifiers kuti aite zvirinani mumamiriro ekunze akanyanyisa.
- Yakaderera-Tembiricha Asphalt: Iyo inozivikanwawo seinodziya-musanganiswa asphalt (WMA), inoshanda nekugadzirisa yechinyakare inopisa-musanganiswa asphalt yekugadzira maitiro kuderedza tembiricha painosanganiswa uye kuiswa asphalt.
Asphalt kusanganisa zvirimwa zvakakosha pakuvaka nekuchengetedza migwagwa nemigwagwa mikuru. Nekudaro, ivo vanogona zvakare kuve kwakakosha sosi yekusvibiswa kwemhepo, kunyanya guruva. Kuburitsa huruva kubva kumiti yeasphalt kunogona kukanganisa hutano hwevanhu nenharaunda. Asphalt kusanganisa zvidyarwa zvinowanzowanikwa mukati meguta kana munzvimbo dzine maguta, uye matambudziko ane guruva ane chekuita nevakuru, veruzhinji, uye vanogadzira zvidyarwa. Zvisungo zvekudzora kusvibiswa kwemhepo zvave kugamuchirwa pasi rese, mazhinji aine mirau yakanangana nekuita uku, uye hapana chirimwa chitsva chakamisikidzwa nhasi pasina hurongwa hwekudzora guruva. Zvakare, kukura kuri kudiwa kweasphalt paving musanganiswa zvinhu zvinoreva kuti kupfuura avhareji kuedza kunofanirwa kushandiswa mukudzora kuburitswa kweguruva kubva kumiti yekusanganisa asphalt.
