Emulsion bitumen ee dusha sare ee yar yar waa shayga ku xidha dhismaha dusha sare ee yar yar. Dabeecaddeeda ayaa ah in ay u baahan tahay in ay la kulanto wakhtiga isku dhafka ah ee dhagaxa iyo wakhtiga furitaanka ee taraafikada ka dib marka laamigu dhameeyo. Si fudud loo dhigo, waxay la kulantaa laba arrimood oo waqti ah. Waqtiga isku dhafka ah waa inuu ahaadaa mid ku filan, iyo furitaanka taraafikada waa inuu ahaadaa mid degdeg ah, taasi waa dhammaan.
Aan mar kale ka hadalno bitumen emulsion. Emulsion bitumen waa emulsion bitumen saliid ku jirta. Waa dareere isku mid ah viscous heerkulka qolka. Waxaa lagu dabaqi karaa si qabow oo uma baahna kuleyl. Waa badbaadin tamar iyo deegaan saaxiibtinimo. Emulsion bitumen wuxuu u qaybsan yahay saddex nooc iyadoo loo eegayo emulsifiers-yada kala duwan ee loo isticmaalo soosaarka: dildilaac tartiib ah, dildilaac dhexdhexaad ah, iyo dildilaac degdeg ah. Bitumen-ka emulsified ee loo isticmaalo dhismaha dusha sare ee dusha sare waa dildilaac tartiib ah iyo dejinta degdega ah ee cationic emulsion bitumen. Noocan ah qaniinyada emulsion-ka waxaa lagu diyaariyaa iyadoo la isticmaalayo dildilaac gaabis ah iyo dejinta degdega ah ee emulsifier-ga bitumen iyo in lagu daro beddelayaasha polymer. Waxay gaari kartaa waqti ku filan oo isku dhafan iyo saameyn deg deg ah. Isku-xidhka u dhexeeya cations iyo dhagaxa waa wanaagsan yahay, sidaas darteed nooca cationic ayaa la doortaa.

Dildilaaca qunyar socodka ah iyo dejinta degdega ah ee emulsion bitumen ayaa inta badan loo isticmaalaa ka hortagga dayactirka waddooyinka. Taasi waa, waxaa loo isticmaalaa marka lakabka hoose uu yahay mid asal ah laakiin lakabka dusha sare ayaa waxyeeloobay, sida dusha sare ee wadada oo siman, dildilaaca, jeexan, iwm.
Habka dhismaha: Marka hore ku buufi lakabka saliidda koollada ah, ka dibna isticmaal shaabad yar oo dusha sare ah / slurry seal si aad u jeexdo. Marka aaggu yara yar yahay, isku darka gacanta iyo laamida bitumen iyo dhagaxa emulsion waa la isticmaali karaa. Laamiga ka dib waxaa loo baahan yahay in la simiyo. Waxaa loo isticmaali karaa si caadi ah ka dib marka la sugo dusha sare si uu u qalalo. Lagu dabaqi karo: dhismaha lakabka khafiifka ah ee 1 cm gudahood. Haddii dhumucdiisu u baahan tahay in ka badan 1 cm, waa in lagu dhejiyaa lakabyo. Kadib hal lakab ayaa qallalan, lakabka xiga waa la jeexjeexi karaa. Haddii ay jiraan dhibaatooyin inta lagu jiro dhismaha, waxaad la xiriiri kartaa adeegga macaamiisha si aad ula tashato!
Dilaaca qunyar socodka ah iyo bitumen-ku-dejinta degdega ah waa shayga sibidhka ee xidhidhiyaha dareeraha ah iyo laami-yar oo dusha sare ah. Si adag u hadla, dhismaha shaabaddii slurry ee la beddelay iyo dusha sare ee yar-yar, dildilaaca gaabis ah iyo dejinta degdega ah ee emulsion bitumen waxay u baahan tahay in lagu daro beddele, taas oo ah, bitumen emulsion la beddelay.
