Kule mihla, i-asphalt pavement isetyenziswa ngokubanzi kulwakhiwo lweendlela ngenxa yeenzuzo zayo ezininzi. Okwangoku, ubukhulu becala sisebenzisa ibhitumene eshushu kunye nebhitumene efakwe emulsified kulwakhiwo lwe-asphalt pavement. Ibhitumene eshushu idla amandla amaninzi obushushu, ingakumbi izixa ezikhulu zesanti kunye nezinto zegrabile ezifuna ukubhaka ubushushu. Imeko yolwakhiwo lwabasebenzi imbi kwaye noxinzelelo lwabasebenzi luphezulu. Xa usebenzisa i-bitumen e-emulsified ekwakheni, ukufudumeza akufuneki kwaye kunokutshizwa okanye kuxutywe kwi-paving kwiqondo lokushisa, kwaye i-pavement yezakhiwo ezahlukeneyo inokugaywa. Ngaphezu koko, ibhitumene efayiweyo inokuhamba iyodwa kwiqondo lobushushu begumbi, kwaye inokwenziwa ibe yibhitumene engumqhagamli wezinto ezahlukeneyo njengoko kufuneka. Kulula ukufezekisa ubukhulu befilimu ye-asphalt efunekayo ngokugalela okanye ukutyhutyha umaleko, ongenakufumaneka ngebhitumene eshushu. Ngokuphucuka kancinane kothungelwano lweendlela kunye neemfuno zokuphuculwa kweendlela zomgangatho ophantsi, ukusetyenziswa kwebhitumene efakwe ibhitumene kuya kuba kukhulu ngakumbi; ngokunyuswa kolwazi ngendalo esingqongileyo kunye nokunqongophala kwamandla kancinane, umlinganiselo webhitumene efakelwe ibhitumene kwiasphalt uya kuba phezulu nangaphezulu. Umda wokusetyenziswa nawo uya kuba banzi kwaye ube banzi, kwaye umgangatho uya kuba ngcono kwaye ubengcono. Ibhitumene e-Emulsified ineempawu zokungabi natyhefu, ezingenavumba, ezingatshiyo, zome ngokukhawuleza kunye nokubopha okuqinileyo. Ayinakuphucula kuphela umgangatho wendlela, ukwandisa ububanzi bokusetyenziswa kwe-asphalt, ukwandisa ixesha lokwakha, ukunciphisa ukungcoliseka kwendalo kunye nokuphucula iimeko zokwakha, kodwa nokugcina amandla kunye nezinto eziphathekayo.
Ibhitumene e-Emulsified ikakhulu yenziwe yibhitumene, i-emulsifier, isizinzi kunye namanzi.
1. Ibhitumene yinto ephambili yebhitumene e-emulsified. Umgangatho we-asphalt uhambelana ngokuthe ngqo nokusebenza kwe-emulsified asphalt.
2. I-Emulsifier yinto ephambili ekubunjweni kwe-asphalt e-emulsified, emisela umgangatho we-asphalt e-emulsified.
3. I-stabilizer inokwenza i-asphalt e-emulsified ibe nokuzinza okulungileyo kokugcinwa ngexesha lenkqubo yokwakha.
4. Ngokuqhelekileyo kufuneka ukuba umgangatho wamanzi ungabi nzima kakhulu kwaye akufanele ube nezinye izinto ezingcolileyo. Ixabiso le-pH yamanzi kunye ne-calcium kunye ne-magnesium plasma inempembelelo kwi-emulsification.
Ngokuxhomekeke kwizixhobo kunye ne-emulsifiers esetyenzisiweyo, ukusebenza kunye nokusetyenziswa kwe-asphalt e-emulsified nayo yahlukile. Ezona zisetyenziswa ngokuqhelekileyo zezi: i-asphalt ye-emulsified eqhelekileyo, i-asphalt e-emulsified ye-SBS eguqulweyo, i-asphalt eguqulwayo ye-SBR eguqulwayo, i-asphalt eyongeziweyo ecothayo eyongeziweyo, i-asphalt e-emulsified permeability ephezulu, i-asphalt ephezulu ye-viscosity emulsified. Ekwakhiweni nasekugcinweni kwe-asphalt pavement, i-asphalt efanelekileyo ye-emulsified inokukhethwa ngokwemiqathango yendlela kunye neepropati.
