Isikrini singenye yezingxenye zesitshalo sokuxuba i-asphalt futhi singasiza isikrini. Kodwa-ke, izimbobo zemeshi esikrinini zivame ukuvinjelwa ngesikhathi sokusebenza. Angazi noma lokhu kungenxa yesikrini noma impahla. Kufanele sikuthole futhi sikuvimbele.

Ngemva kokubheka nokuhlaziya inqubo yokusebenza yesitshalo sokuxuba i-asphalt, kunganqunywa ukuthi ukuvala izimbobo zesikrini kubangelwa izimbobo ezincane zesikrini. Uma izinhlayiya zezinto ezibonakalayo zizikhudlwana kancane, ngeke zikwazi ukudlula emigodini yesikrini kahle futhi kuzovaleka. Ngaphezu kwalesi sizathu, uma amatshe aqukethe inani elikhulu lezinhlayiya zamatshe noma ama-flakes afana nenaliti eseduze kwesikrini, izimbobo zesikrini zizovaleka.
Kulokhu, ama-chips amatshe ngeke ahlolwe, okuzothinta kakhulu isilinganiso sokuxuba kwengxube, futhi ekugcineni kuholele ekutheni ikhwalithi yomkhiqizo wengxube ye-asphalt ingahlangabezani nezidingo. Ukuze ugweme lo mphumela, zama ukusebenzisa isikrini esilukiwe ngentambo yensimbi enobubanzi obukhulu, ukuze ukhuphule ngempumelelo izinga lokuphasa kwesikrini futhi uqinisekise ikhwalithi yetiyela.
