Ewe, izityalo zangoku ezimileyo zikwazi kakhulu ukubandakanya iPavement ye-Asphalt eRecycled (RAP). Izixhobo zokutyisa ezikhethekileyo zazisa imathiriyeli yeRAP kwigubu lokomisa okanye umxube ngamaxabiso alawulwayo. Uyilo oluphezulu luvumela umxholo we-RAP ukusuka kwi-20% ukuya ngaphezulu kwe-50%, ngokuxhomekeke kwiteknoloji esetyenziselwa ukulawula umsi kunye nokuqinisekisa ukufudumeza okufanayo ngaphandle kokutshisa i-binder endala.

Ziziphi iimfuno zendawo yokufakela?

Iimfuno zendawo ziyahluka ngokusekelwe kumthamo kunye neemfuno zokugcina. Isityalo esimileyo esisemgangathweni esiphakathi sikholisa ukufuna indawo yemitha eyi-3,000 ukuya kwi-5,000 yesikweri seemitha. Lo mmandla kufuneka uhlalise inqaba yeplanti, imigqomo yokutya okubandayo, izisele zokugcina, iitanki zamafutha, kunye nendawo yokulawula iilori. Umthamo wokuthwala umhlaba ukwangumba obalulekileyo, odinga isiseko esomeleleyo sekhonkrithi.

Ngaba i-automation inzima ukufunda kubasebenzisi?

Iisistim zolawulo zale mihla ziyilwe ngonxibelelwano olusebenziseka lula, oluhlala lubonisa izikrini zomzobo kunye neemenyu ezicacileyo. Ngelixa ingqiqo esisiseko inzima, abavelisi babonelela ngeenkqubo zoqeqesho ezibanzi. Uninzi lwabaqhubi banokuba nobuchule kwiiveki ezimbalwa, besebenzisa izinto ezizenzekelayo ezibamba izibalo ezinzima kunye nohlengahlengiso ngokuzenzekelayo.

Isiphelo kunye neeNgcebiso zeQhinga

I isityalo esimileyo sokuxuba i-asphalt Ihlala ilitye lembombo lemveliso ye-asphalt esebenzayo, ekumgangatho ophezulu kumaziko amakhulu. Ukuphakama kwayo ngokuchaneka, amandla, kunye nolawulo lokusingqongileyo kuyenza ibe lukhetho oluqinisekileyo lweekontraka ezinzulu kunye neearhente zikarhulumente ezizinikele kwiinjongo zophuhliso lwexesha elide. Njengoko iteknoloji iqhubela phambili ukuya kwiinkqubo ezikrelekrele, eziluhlaza, nezisebenzayo ngakumbi, isindululo sexabiso sezixhobo ezimileyo siyaqhubeka nokomelela.

Ngubani ofanele atyale imali kwesi sisombululo?

• Iifemu ezinkulu zokwakha: Iinkampani ezilawula uthungelwano olubanzi lweendlela ezinkulu okanye iiprojekthi zeminyaka emininzi zasedolophini ziya kuxhamla kakhulu kwimveliso ephezulu kunye nokuthembeka.
• Amaqumrhu kaRhulumente: Amasebe omsebenzi kawonke-wonke afuna uqinisekiso olungqongqo lomgangatho kunye nokukwazi ukuvelisa iintlobo ezahlukeneyo zokuxuba ziya kufumana ulungelelwaniso lomxube webhetshi.
• Ababoneleli ngeMathiriyeli abaKhethekileyo: Amashishini agxile kwimigangatho yepremiyamu efana ne-SMA okanye imixube yomxholo we-RAP ephezulu afuna ulawulo oluchanekileyo olunikezwa ziinkqubo ezimileyo.

Kwabo bajonga inyathelo elilandelayo, isindululo sicacile: yenza uhlalutyo olucokisekileyo lwemithamo yemathiriyeli eqikelelweyo kwaye udibanise iimfuno zokwahluka. Zibandakanye neenjineli ezinamava ukuyila uyilo olukhulisa ukuhamba kwezinto kunye nobungqina bexesha elizayo umsebenzi wakho ngokuchasene nokuqiniswa kwemithetho yokusingqongileyo. Utyalo-mali kumgangatho ophezulu isityalo esimileyo sokuxuba i-asphalt kumvelisi oqinisekisiweyo, onamava akathengi nje izixhobo; ifumana i-asethi yeqhinga eqhuba ukugqwesa kweziseko zophuhliso kumashumi eminyaka.
