rhoqo kakhulu unyango umphezulu asphalt ukuba zingangenwa lwezoyilo ezahlukeneyo ezisetyenzisiweyo ngebhitumene emulsion - uhlobo lwenkqubo apho amasuntswana becandelo eziphambili emelwe lusanda zolwelo ngokohlobo izinto ezahlukeneyo. Kule medium inikwa isenzo kwakuse, esetyenziswa inxaxheba ongeziweyo ezahlukeneyo - izixubisisi. Yinto engenakuphikwa ukuba zingangenwa bituminous kuluncedo ngokwemiqathango kwezibonelelo ugcino kunye nococeko esingqongileyo. Ngokuqhelekileyo, iingcali umsebenzi bajamelene iintlobo ezahlukeneyo izinto isiseko. Ngoko imixube wafumana zinokwahluka kakhulu enye kwenye iipropati.
Nayiphi emulsion itha zifuna ukongeza wesinyibilikisi, isixa salo kufanele zichaneke kakuhle. Kungenjalo ukuhlamba kweekhomponenti ngamnye okanye ukudilizwa ngokugqithisileyo umxube zinokwenzeka. Isinyibilikisi lisetyenziswa nokunciphisa arhente nokwakhiwa iqondo viscosity. Ngokumalunga amanzi equlethwe ngendlela efanayo ukuba zingangenwa cationic umxube ngoko novakalelo kancinci ukuya umthamo yongezwe ngaphezu nucleoside anionic. Le yokugqibela kubo usabela kakhulu isixa ubumdaka eziqulethwe kulwelo ongezwe.
Xa usenza imixube, nofakelo esikhethekileyo imveliso yebhitumene emulsion, nto leyo eye isakhiwo enzima. Oku kuquka: a unit main kunye lokusila colloid, iinkqubo zolawulo zekhompyutha, wemithi imigca zamanzi kunye itha, umthamo yokugcina izinto ezahlukeneyo kwakunye imibhobho iimpompo. Umsebenzi siqhutywa ngokusekelwe wokuxuba ngokucokisekileyo, ukwakhiwa icebisa emulsification ngakumbi. Umgangatho imveliso yokugqibela kuxhomekeke kakhulu kwi ukufana umxube kunye pretreatment.
Phantse zonke iiyunithi zokusebenza ezenziwe ngezinto hayi ngokuxhomekeke umhlwa, nto leyo eyenza kube lula ukufezekisa ubomi inkonzo esiphezulu. Oku kuyinyani ngakumbi kweeyunithi kunye iindawo apho qhagamshelana ngqo ne zolwelo medium. Njengangoku zisetyenziselwa kuphela izixhobo automated ukufumana imveliso esemgangathweni, xa ibhitumene emulsion uyahlangabezana nazo zonke iimfuno. Inani kunye iimpawu imveliso alinganiswa yi nemishini ekhethekile. Ngokusekelwe yokuba iimpawu umxube lokugqibela baxhomekeke izixubisisi kuvela silwenza kwizixhobo ekwaziyo owanyayo izakhi ngeendlela ezimbini.
Phambi kokuba emulsion ngebhitumene lisetyenziswa umphezulu, isiseko kufuneka ilungiswe ngenyameko. Ukuze balahle ukutyabeka endala kunye ubutyobo ezahlukeneyo, emigodini esalo milimitha ezinkulu kuno ezintathu. Ngaphezu koko, priming lwenziwa kunye nokwakheka emulsion. Ingakumbi umxube flow impembelelo uhlobo komhlaba ukuphathwa. Xa sijonga Ibukisheni ingafunyanwa ne ukusetyenziswa avareji imveliso. Xa amanzi aphuma ngokomphushu ukusuka isisombululo kumphezulu iya kuhlala obhityileyo umboniso yebhitumene, oku kulandelayo zokukhusela ukutyabeka.
