Asphalt imvura ine viscous organic ine mutema mutema uye inonyungudika mucarbon disulfide (mvura yegoridhe-yero, inonhuwa zvakaipa). Dzinowanzovapo muchimiro cheasphalt kana tara.
Asphalt inogona kunyanya kukamurwa kuita marudzi matatu: marasha tar pitch, petroleum asphalt uye yeakasikwa asphalt: pakati pavo, marasha tar pitch ndeye-chigadzirwa chekubika. Petroleum asphalt ndiyo inosara mushure mekudzikiswa kwemafuta asina kukora. Natural asphalt inochengetwa pasi pevhu, uye mamwe anoita mamineral deposits kana kuungana pamusoro pevhu.
Bhitumini muchimiro cheasphalt inowanikwa nekunatsa mafuta asina kuchena kuburikidza nekupatsanurwa. Vane mapoinzi ekubika mumafuta asina kuchena uye zvinhu zvinorema mumafuta asina kuchena, saka anozowanikwa pazasi peshongwe dzekuparadzanisa.
Asphalt iri muchimiro chetara inowanikwa nekurapa organic matter (kunyanya marasha) kuburikidza necarbonization.
Asphalt inowanzoshandiswa pakuvaka, sekugadzira migwagwa. Migwagwa yakagadzirwa neasphalt nematombo inonzi asphalt roads.
