Ngokwezifundo zangaphambili kunye nophando lwentsimi, i-asphalt pavement ichaphazeleka ngokuguquguquka, ukufunxa, i-oxidation, kunye neempendulo ze-photochemical kwi-pavement, kwaye umlinganiselo we-asphalt wehla ngokukhawuleza phantsi kweemeko zokuqala zokuguga, okubangelwa i-brittle and fragile pavement. Ngokhukuliseko olongezelelekileyo lwe-asphalt, i-pavement emdala ngokuphakathi ibonisa umxholo wayo. I-asphalt pavement ingena kwinqanaba lokuguga ngenxa yokukrazula okuqhubekayo kunye nemozulu, apho amatye abonakaliswe kwiincinci ezincinci kwi-pavement.

Ngexesha lenkqubo yokuguga, ukukhubazeka kunye namandla okwakhiwa kwendlela yendlela yehla. Ekugqibeleni, unxunguphalo olukhulu lwendlela yabahambi ngeenyawo lwenzeka ngohlobo lweentanda ezinqamlezileyo, iintanda zengwenya, imingxuma kunye nokuruleka. Le nkqubo inciphisa kakhulu i-viscosity kunye ne-brittleness, inyusa i-ductility kunye nokuguquguquka, kwaye yenza i-asphalt ingabi lula ukukrazula kunye nokuwohloka.
Ngokungafaniyo neengubo zokutywina zakudala, usetyenziso olunye lwecandelo lovavanyo lokuhlaziywa kwe-asphalt lungena kwipavumente ukuze ubuyisele kwaye ubuyisele itela kunye ne-asphalt elahlekileyo ngenxa yomphezulu we-oxidation ongaphantsi kakhulu kune-asphalt ekhuselweyo. Ikwatywina kwaye ikhusele indlela yokuhamba emanzini, ukukhanya kwelanga kunye nongcoliseko lweekhemikhali, iphucula kakhulu ukuqina, ubomi kunye nokunciphisa umtsalane we-asphalt. Abavelisi bokuxuba i-asphalt bakukhumbuza ukuba ukugcinwa okufanelekileyo kuyisitshixo sokukhusela i-asphalt kwizinto zangaphandle ezinxibayo.
