Izinto zesamente ezisetyenziswa kwi-micro-surfacing i-bitumen eguquliweyo eguqulweyo. Ziziphi iimpawu zayo? Makhe sithethe ngendlela yokwakha ye-microsurfacing kuqala. Umphezulu we-Micro Surfacing usebenzisa i-micro surfacing paver ukuze usasaze ngokulinganayo ibakala elithile lamatye, isihluzi (isamente, ikalika, njl.njl.), ibhitumene eguquliweyo, amanzi kunye nezinye izongezo endleleni ngokomlinganiselo. Le ndlela yokwakha ineengenelo ezithile kuba imathiriyeli yokudibanisa esetyenzisiweyo ilungiswa ngokucothayo ukuseta ibhitumene eqingiweyo.
I-micro-surface ine-anti-wear engcono kunye ne-anti-slip properties. Xa kuthelekiswa ne-slurry sealants eqhelekileyo, umphezulu we-micro-surface unokwakheka okuthile, onokuxhathisa ukungqubana kwemoto kunye nokutyibilika kunye nokuqinisekisa ukhuseleko lokuqhuba. Isiseko sale ngongoma kukuba i-samente esetyenziswe kwi-micro-surfacing kufuneka ibe neempawu ezintle zokudibanisa.
Emva kokufaka izilungiso kwi-bitumen eqhelekileyo ye-emulsified, iipropati ze-bitumen ziphuculwe, kunye nokusebenza kokubambisana kwe-micro-surface kuphuculwe. Oku kwenza umphezulu wendlela emva kokwakhiwa ubenokuqina okungcono. Ukuphuculwa kokusebenza kobushushu obuphezulu nobuphantsi bepavumente.
Olunye uphawu olubalulekileyo lwebhitumene eguquliweyo yokucotha kunye nokubeka ngokukhawuleza i-emulsified emulsified esetyenziselwa ukwakhiwa kwe-micro-surfacing kukuba inokwakhiwa ngoomatshini okanye ngesandla. Ngenxa yeempawu zayo ezicothayo ze-demulsification, ihlangabezana neemfuno zokuxuba umxube. Oku kwenza ukuba ulwakhiwo lube bhetyebhetye, kwaye indlela efanelekileyo yokwakha inokukhethwa ngokweyona meko, ivumela ukuba i-paving scheme ye-manual ifezekiswe.
Ukongezelela, izinto ze-cementing kwi-micro surface nazo zinempawu zokumisela ngokukhawuleza. Olu phawu luvumela indawo yendlela ukuba ivulwe kwi-traffic 1-2 iiyure emva kokwakhiwa, ukunciphisa impembelelo yokwakha kwi-traffic.
Enye ingongoma kukuba i-bonding material esetyenziselwa ukwakhiwa kwe-micro-surfacing i-liquid kwiqondo lokushisa lokushisa kwaye ayifuni ukufudumeza, ngoko kukwakhiwa okubandayo. Oku akugcini nje ukuphucula ukusebenza kakuhle kokwakhiwa, kodwa kunciphisa ukusetyenziswa kwamandla, okuhambelana nombono wokugcinwa kwamandla kunye nokukhuselwa kwendalo. Xa kuthelekiswa nokwakhiwa kwebhitumene eshushu yendabuko, indlela yokwakha ebandayo ye-micro-surfacing ayivelisi iigesi eziyingozi kwaye inempembelelo encinci kwindalo kunye nabasebenzi bokwakha.
Ezi mpawu ziyimfuneko yokuqinisekisa umphumo wokwakha kunye neempawu eziyimfuneko. Ngaba ibhitumene etyhidiweyo oyithengileyo inazo ezi mpawu?
