Umsasazi we-asphalt sisixhobo sobuchwepheshe obuphezulu esisetyenziselwa ukusasaza i-asphalt e-emulsified, i-asphalt ehlanjululweyo, i-asphalt eshushu kunye ne-high-viscosity modified asphalt. Isetyenziselwa ikakhulu ukubeka i-oyile yokungena, i-oyile yokungena kwamanzi kunye nomgangatho wokudibanisa umgca ophantsi wendlela ephezulu ukuphucula umgangatho wendlela.
Umsasazi we-asphalt udibanisa imisebenzi yokugcina i-asphalt, ukufudumeza, ukusasazeka kunye nokuthutha, kwaye ixhotyiswe ngepompo ye-asphalt ezimeleyo, enokuqonda ukulayishwa okuzimeleyo kunye nokukhulula i-asphalt.
Abasasazi be-asphalt banoluhlu olubanzi lweemeko zesicelo, kubandakanywa kodwa kungaphelelanga kwiindlela zasezidolophini, iindlela ezinkulu kunye nolunye ulwakhiwo lweendlela.

Ekwakhiweni kwendlela yasezidolophini, ukusetyenziswa kwezinto eziphezulu ze-asphalt kubaluleke kakhulu. Abasasazi be-asphalt banokuqinisekisa ukuhanjiswa okufanayo kwezinto ze-asphalt kunye nokuphucula ukuqina kunye nobuhle beendlela.
Ukwakhiwa kohola wendlela kuneemfuno eziphezulu zezixhobo ze-asphalt, kunye nezinto eziphezulu ze-asphalt kunye neteknoloji yokusasaza i-asphalt ephezulu iyafuneka ukuze kuqinisekiswe ukhuseleko kunye nokuqina kweendlela ezihamba phambili.
Abasasazi be-asphalt nabo bafanelekile kwezinye iindawo zokwakha iindlela, kubandakanywa neendlela zasemaphandleni, iindlela zesekondari zasezidolophini, njl.
Abasasazi be-asphalt baneempawu zokutshiza umgangatho ophezulu, ukusebenza kakuhle kunye nokuchaneka okuphezulu kokwakhiwa. Indlela yokutshiza ithatha isitshizi ukuqinisekisa ukuhanjiswa okufanayo kwe-asphalt. Isantya sokutshiza sinokufikelela kwi-200-300 square metres ngomzuzu, siphucula kakhulu ukusebenza kakuhle kolwakhiwo. I-teknoloji ephezulu kunye nezixhobo zenza ukuba i-asphalt spreader ilungelelanise ngokuzenzekelayo iiparitha ezifana nokutshiza ububanzi kunye nesantya sokuqinisekisa ukuba imveliso egqityiweyo idibana neenkcukacha.
