Isikrini sesinye samacandelo kwisityalo sokuxuba i-asphalt kwaye sinokunceda izixhobo zesikrini. Nangona kunjalo, imingxunya yemesh kwiscreen ihlala ivaliwe ngexesha lokusebenza. Andazi nokuba oku kungenxa yesikrini okanye izinto eziphathekayo. Kufuneka siyifumanise kwaye siyinqande.

Emva kokujonga kunye nokuhlalutya inkqubo yokusebenza kwesityalo sokuxuba i-asphalt, kunokumiselwa ukuba ukuvala imingxuma yesikrini kubangelwa imingxuma encinci yesikrini. Ukuba amasuntswana ezinto eziphathekayo makhulu kancinane, akanakukwazi ukudlula kwimingxunya yesikrini kakuhle kwaye ukuvaleka kuya kwenzeka. Ukongeza kwesi sizathu, ukuba amatye aqulethe inani elikhulu lamaqhekeza amatye okanye ii-flakes ezifana nenaliti zisondele kwisikrini, imingxuma yesikrini iya kuvalwa.
Kule meko, iitshiphusi zamatye aziyi kujongwa, eziya kuchaphazela kakhulu umxube womxube womxube, kwaye ekugqibeleni zikhokelele kumgangatho wemveliso ye-asphalt yomxube ongahlangabezani neemfuno. Ukuze uthintele esi siphumo, zama ukusebenzisa isikrini socingo olulukiweyo lwentsimbi enobubanzi obungqingqwa, ukuze unyuse ngokufanelekileyo izinga lokupasa kwesikrini kwaye uqinisekise umgangatho we-asphalt.
