Uyilo lwenkqubo yokulawula, inxalenye ephambili yesityalo sokuxuba i-asphalt, yaziswa kuwe. Ezi zimbini zilandelayo zimalunga nokugcinwa kwayo kwemihla ngemihla. Ungawuhoyi lo mba. Ukugcinwa kakuhle kuya kunceda inkqubo yokulawula ukuba idlale indima yayo, ngaloo ndlela ikhuthaza ukusetyenziswa kwesityalo sokuxuba i-asphalt.

Njengezinye izixhobo, inkqubo yokulawula isityalo sokuxuba i-asphalt kufuneka nayo igcinwe yonke imihla. Umxholo wokugcina uquka ukukhutshwa kwamanzi adibeneyo, ukuhlolwa kweoli yokuthambisa kunye nokulawulwa kunye nokugcinwa kwenkqubo ye-compressor yomoya.
Ekubeni ukukhutshwa kwamanzi adibeneyo kubandakanya yonke inkqubo ye-pneumatic, kuyimfuneko ukukhusela amaconsi amanzi ekungeneni kumacandelo okulawula. Xa isixhobo somoya sisebenza, khangela ukuba i-oyile droplet ye-oyile mister iyahlangabezana neemfuno kunye nokuba umbala we-oyile uqhelekile. Musa ukuxuba ukungcola okunjengothuli nokufuma kuyo. Ulawulo lwemihla ngemihla yenkqubo ye-compressor yomoya ayikho into engaphezulu kwesandi, ukushisa kunye neoli yokuthambisa, njl., Ukuqinisekisa ukuba ezi zinto azidluli imigangatho echaziweyo.
