Ngokubhekiselele kwimveliso, ulawulo linyathelo lokuqala lokuqinisekisa inkqubela phambili esebenzayo yomsebenzi, ngakumbi xa kuziwa kwiiprojekthi ezithile ezinkulu, kubandakanywa nolawulo lwezixhobo, ulawulo lweenkqubo zokuvelisa, njl njl. Ulawulo lwezityalo zokuxuba i-asphalt ehambayo. ibandakanya imiba eyahlukeneyo efana nolawulo lwezixhobo kunye nolawulo lokhuseleko lwemveliso, kwaye inkalo nganye ibaluleke kakhulu.
Okokuqala, ulawulo lwezixhobo. Ukuba izixhobo azikwazi ukusebenza ngokufanelekileyo, imveliso ayikwazi ukuqhubeka, echaphazela kakhulu inkqubela yeprojekthi yonke. Ngoko ke, ukulawulwa kwezixhobo zesityalo sokuxuba i-asphalt kuyimfuno esisiseko, ebandakanya umsebenzi wokuthambisa, izicwangciso zokugcinwa, kunye nokulawulwa kwezixhobo ezinxulumene nezixhobo.
Phakathi kwabo, eyona nto ibalulekileyo kukuthanjiswa kwezixhobo zezityalo zokuxuba i-asphalt. Amaxesha amaninzi, isizathu sokuba ezinye izixhobo zisilele ngenxa yokungathanjiswa ngokwaneleyo. Ngenxa yesi sizathu, kuyimfuneko ukwenza izicwangciso zokugcinwa kwezixhobo ezihambelanayo, ngokukodwa ukwenza umsebenzi omhle wokuthanjiswa kwamacandelo abalulekileyo. Oku kungenxa yokuba emva kokungaphumeleli kwamacandelo aphambili, umsebenzi wawo wokutshintshwa nowokugcina udla ngokuba nzima yaye udla ixesha, nto leyo echaphazela ukusebenza kakuhle.
Emva koko, ngokwemeko yangempela, qulunqa ugcino oluhambelanayo kunye nezicwangciso zokuhlola. Inzuzo yokwenza oku kukuba ezinye izixhobo zokuxuba i-asphalt ezinokungaphumeleli kunokupheliswa kwi-bud. Kwamanye amalungu athanda ukonakala, iingxaki kufuneka zijongwe rhoqo, ezinje ngokuxuba uludaka, i-lining, isikrini, njl.
Ukongeza, ukuze kuncitshiswe impembelelo ngexesha leprojekthi, indawo yesityalo se-asphalt esihambayo ihlala ikude, ngoko ke kunzima ukuthenga izixhobo. Ukuthathela ingqalelo ezi ngxaki zisebenzayo, kuyacetyiswa ukuba uthenge inani elithile lezesekeli kwangaphambili ukuze kube lula ukutshintshwa ngexesha elifanelekileyo xa kuvela iingxaki. Ngokukodwa kwiindawo ezisengozini ezifana nokuxuba i-slurry, i-lining, isikrini, njl., ngenxa yomjikelezo omude wokusabalalisa, ukwenzela ukuba ugweme ukuchaphazela ixesha lokwakha, iiseti ezi-3 zezixhobo zithengwa kwangaphambili njengeendawo zokuphumla.
Ukongezelela, ulawulo lokhuseleko lwenkqubo yonke yokuvelisa ayinakuhoywa. Ukuze wenze umsebenzi omhle ekulawuleni ukhuseleko lwezityalo zokuxuba i-asphalt kunye nokuqinisekisa ukuba akukho zingozi zokhuseleko kumatshini kunye nezixhobo kunye nabasebenzi, amanyathelo okuthintela ahambelanayo kufuneka athathwe kwangaphambili.
