Ngaba iibhitumeneiteyiphu engangeni manzi woyike amanzi emva kokwakhiwa?

• Ibhitumenetape engenamanzi ayiyi koyika amanzi emva kokwakhiwa.

Abantu abaninzi banenkxalabo malunga nokuba baya koyika na amanzi emva kokwenza ibhitumene yokuthintela amanzi.Enyanisweni, oku kukhathazeka akuyomfuneko.Icandelo eliphambili le-bitumen ye-tape engenamanzi yi-asphalt kunye nezixhobo zayo ezilungisiweyo.I-gum kunye ne-asphalt grease equlethwe kuyo inokuyenza ibe neqondo elithile lokuguquguquka kunye ne-ductility.Iyakwazi ukumelana neempembelelo ezithile kunye nokungcangcazela emva kokwakhiwa, kwaye ayiyi kuchaphazeleka kwiiCracks okanye iikhefu ezibangelwa ukukhukuliseka kwamanzi.Kwangaxeshanye, i-asphalt engangeni manzi ingenza umaleko oqinileyo kunye noxineneyo wokumelana nomoya wangaphandle kunye nemvula, ngaloo ndlela ikhusela isakhiwo ekukhukulisekeni kwamanzi kunye nomonakalo.Ngoko ke, phantsi kokusetyenziswa okuqhelekileyo, i-tape ye-bitumen engenamanzi ayiyi koyika amanzi emva kokwakhiwa.

• Ukumelana namanzi kweibhitumenetape engenamanzi

Iteyiphu yokuthintela amanzi yebhitumene inokumelana kakuhle namanzi kwaye inokumelana nokuntywiliselwa kunye nokugqwala kumanzi anjengamanzi emvula kunye namanzi aphantsi komhlaba ixesha elide.Isizathu esiphambili kukuba izithako zayo ziqulethe umlinganiselo othile wegrisi ye-asphalt kunye ne-colloid, enokuthi yenze umaleko oqinileyo kunye noxineneyo olungangeni manzi.Ngokufanelekileyo itywina i-pores kunye neentanda kwizakhiwo ukukhusela ukufuma ekudluleni.Ngelo xesha, i-asphalt impahla engenamanzi ngokwayo nayo ine-asidi efanelekileyo kunye nokuchasana kwe-alkali, kwaye ayiyi kuchaphazeleka ngezinto ezifana nokungcoliswa komoya kunye nokulahlekelwa yimpembelelo yokukhusela ngexesha lokusetyenziswa.

Isiphelo:I-tape ye-bitumen engenamanzi ayiyi koyika amanzi emva kokwakhiwa.Kunoko, inokumelana nokuchasana kwamanzi kunye nokumelana nokugqwala, okunokukhusela isakhiwo ekukhukulisekeni kwamanzi kunye nokwandisa ubomi bayo benkonzo.Ukuze kugcinwe umsebenzi wayo oqhelekileyo, kucetyiswa ukuba kwenziwe ukugcinwa rhoqo kunye nokuhlolwa kunye nokujongana nazo naziphi na iingxaki ezifunyenwe ngexesha elifanelekileyo.

Ngokuphathelele iteyiphu engangeni manzi, sikwavelisa iteyiphu ye-butyl engenamanzi enesiphumo esifanayo.Ukongeza, kukho iteyiphu yokutsala kunye neteyiphu yokulumkisa abathengi ukuba bakhethe kuyo.Xa uthenga iteyiphu, nceda ujonge uphawu lwe-S2!
