Asphalt kusanganisa miti inoumbwa nehurongwa hwakawanda, imwe neimwe ine mabasa akasiyana. Iyo yekupisa system ndiyo kiyi yekushanda kwemidziyo uye ine simba guru pakushanda uye kuchengetedzwa kwemidziyo. Mazuva ano, mamwe matekinoroji ekunze anowanzo kushandisa gasi kupisa masisitimu, asi masisitimu aya anodhura uye haana kukodzera kune mamwe makambani.
KuChina, masisitimu anowanzo shandiswa ekupisa anogona kukamurwa kuita matatu akasiyana mafomu, anoti marasha-akavakirwa, mafuta-akavakirwa uye gasi-yakavakirwa. Zvadaro, maererano nehurongwa, kune matambudziko akawanda makuru, kunyanya kusanganisira kuti madota ari muhupfu hwemarasha chinhu chisingabatiki. Inobatwa nehurongwa hwekudziya kweasphalt mixing plant, yakawanda yemadota inopinda musanganiswa weasphalt. Uyezve, madota ane acidic, iyo inoderedza zvakananga kunaka kweasphalt musanganiswa, iyo isingagoni kuvimbisa hupenyu hwebasa rechigadzirwa cheasphalt. Panguva imwecheteyo, hupfu hwemarasha hunopisa zvishoma nezvishoma, saka zvakaoma kupisa zvakakwana munguva pfupi, zvichiita kuti pave nemafuta mashoma uye kushandiswa kwesimba.
Kwete izvozvo chete, kana marasha achishandiswa sehuni, kurongeka kwekugadzira kunogona kuwanikwa kune zvigadzirwa zvechinyakare zvinoshandiswa mukugadzirisa zvinogumira, izvo zvinoderedza zvakananga kurongeka kwekugadzirwa kwemusanganiswa. Uyezve, kupisa kwehupfu hwemarasha mumiti yekusanganisa asphalt kunoda kamuri yakakura yekupisa, uye zvinhu zvinoramba zviri mukamuri yekupisa zvigadziriso zvine njodzi, izvo zvinoda kugara zvichiongororwa nekutsiviwa, uye mutengo wekugadzirisa wakanyanya kukwirira.
Zvino, kana gasi rakashandiswa seyakagadzirwa, mwero wekushandisa wakanyanya kwazvo unogona kuwanikwa. Iyi combustion system inokurumidza uye inogona kuchengetedza nguva yakawanda. Nekudaro, iyo yekupisa sisitimu yeasphalt yekusanganisa zvidyarwa zvinokuchidzirwa negasi zvakare ine zvakawanda zvinokanganisa. Inoda kubatanidzwa kune pombi yegasi yechisikigo, iyo isina kukodzera mamiriro ezvinhu painoda kufambisa kana kazhinji inoda kutamiswa. Uyezve, kana pombi yegasi yechisikigo iri kure, zvinodhura mari yakawanda kumisa mavharuvhu uye kuisa mapaipi nemimwe midziyo yebetsero.
Bva, zvakadiniko negadziriro yokupisa iyo inoshandisa mafuta emafuta sehuni? Iyi sisitimu haingogone kuchengetedza mutengo wekugadzira, asiwo kuita kuti zvive nyore kudzora tembiricha yemafuta. Iyo yekupisa sisitimu yeasphalt kusanganisa zvidyarwa zvinokuchidzirwa nemafuta emafuta zvine zvakanaka zvehupfumi zvakanakira, uye inogona zvakare kuwana yakakodzera kupisa simba nekudzora huwandu hwemafuta emafuta.
