Ngenxa yezinto eziluhlaza okanye indlela ezisetyenziswa ngayo, izityalo zokuxuba i-asphalt ziya kuxhomekeka kwinqanaba elithile lokunxiba ngexesha lokusetyenziswa kwansuku zonke. Ukuba azilawulwa okanye zilungiswa kwangethuba, zinokonakala xa sele zidibene nomoya, amanzi emvula, njl njl. ixesha elide. Ukuba iinxalenye zesityalo sokuxuba i-asphalt zixutywe kakhulu, ubomi benkonzo kunye nokusebenza okuqhelekileyo kwezixhobo zonke kuya kuchaphazeleka.

Ke ngoko, kubaluleke kakhulu ukuba izityalo zokuxuba i-asphalt zenze umsebenzi olungileyo wonyango olwahlukeneyo ukuthintela iindawo zazo ukuba zingagqwali. Ukuze ufezekise le njongo, ngakwesinye icala, xa ukhetha izinto zesityalo sokuxuba i-asphalt, izinto eziphathekayo ezinokumelana nokubola kakuhle kufuneka zikhethwe kangangoko kunokwenzeka. Ngakolunye uhlangothi, kuyimfuneko ukunciphisa i-corrosion of the surface of parts ngokuhlukanisa umoya kunye nezinye iindlela, kunye nokuthintela umonakalo wokudinwa kwamalungu, njengokuqhekeka kunye ne-peeling surface.
Ukuze kuthintelwe ukwenzeka kwezi zinto zingasentla, icandelo elithambileyo lingakhethwa ukuhluzwa ngexesha lokuvelisa; ukungena, ukucima kunye nezinye iindlela zingasetyenziselwa ukwandisa ubulukhuni beendawo; kwaye xa uyila imilo yamacandelo, umphumo wokunciphisa ukucwangciswa kwengxabano kufuneka uphinde uqwalaselwe.
