Iyo yose asphalt yekusanganisa simiti inosanganisirawo tangi yekudziya, uye kunaka kwechigadzirwa chekupedzisira kunoenderana zvakanyanya nekushandiswa kwakakodzera kwebhitumini yekudziya tangi. Aya anotevera ndiwo chaiwo maitiro ekushandisa kune yako referensi.
Muchigadziro chekushandisa bhitumini yekupisa matangi, zvakakosha kutarisisa maitiro ayo ekuchenesa, izvo hazvifanirwe kungoitwa chete nguva dzose, asi zvakare kunyatsotevedzera maitiro. Kutanga shandisa tembiricha inenge 150 madhigirii kupfavisa bhitumini uye kuiyerera kunze, uye ipapo shandisa chiedza chekuchenesa mumiririri kubvisa zvachose zvikamu zvakasara pamadziro emidziyo.

Pamusoro pekuchenesa, tembiricha ndiyo zvakare kiyi yekushandiswa kwebhitumini yekudziya matangi. Pane zvimwe zvinodiwa pakupisa. Tichifunga kuti chemikemikari yebhitumen pachayo inonzwa zvakanyanya kune tembiricha, kana tembiricha yakakwira kupfuura 180 ° C, iyo asphaltene inoora muKunaya kwemahara kabhoni, carbides uye asphaltene kuchakanganisa zvakanyanya ductility uye kunamatira kwebhitumini, kushatisa zvivakwa. uye kushanda kwebhitumini. Nokudaro, kupisa kwekushisa uye kushanda kwebhitumini yekupisa tangi inofanira kunyatsodzorwa kana ichipisa. kupisa nguva.
