Ngokwezifundo zangaphambilini kanye nophenyo lwasensimini, i-asphalt pavement ithintwa ukuguquguquka, ukumuncwa, i-oxidation, kanye nokusabela kwe-photochemical komgwaqo, futhi isilinganiso se-asphalt sehla kakhulu ngaphansi kwezimo zokuqala zokuguga, okuholela ekugugeni okuqinile futhi okubuthakathaka. Ngokuguguleka okwengeziwe kwetiyela, umgwaqo ogandaywe osekhulile udalula okuqukethwe kwawo. I-asphalt pavement ingena esigabeni sokuguga ngenxa yokudabula okuqhubekayo kanye nesimo sezulu, lapho amatshe evezwa khona izinhlayiya ezincane endleleni.

Phakathi nenqubo yokuguga, ukukhubazeka namandla esakhiwo se-pavement kuncipha. Ekugcineni, usizi olukhulu lokuhamba komgwaqo lwenzeka ngendlela yokuqhekeka komugqa, imifantu yezingwenya, imigodi kanye nokuruthwa. Le nqubo inciphisa kakhulu i-viscosity kanye ne-brittleness, ikhulisa i-ductility kanye nokuguquguquka, futhi yenza i-asphalt ingajwayele ukuqhekeka nokuwohloka.
Ngokungafani nezingubo zophawu zakudala, ukusetshenziswa okukodwa kwesigaba sokuvuselela itiyela kungena endaweni egandayiwe ukuze kubuyiselwe futhi kuthathelwe indawo itiyela netiyela elalahleka ngenxa yendawo ye-oxidation encane kakhulu kune-asphalt evikelwe. Iphinde ivale futhi ivikele imigwaqo emanzini, ekukhanyeni kwelanga nasezintweni ezingcolisa amakhemikhali, ithuthukisa kakhulu ukuqina, ukuphila kanye nokunciphisa ukukhanga kwetiyela. Abakhiqizi bokuxuba i-asphalt bakukhumbuza ukuthi ukugcinwa okufanele kuyisihluthulelo sokuvikela i-asphalt ezicini zangaphandle ezigqoka futhi ziklebhule.
