Asifalt y'amabara, izwi kandi nka sima y'amabara, ni sima yigana ibice bya peteroli ya peteroli kandi ihindurwa no kuvanga amavuta ya peteroli hamwe na SBS ihindura hamwe nibindi bikoresho bya shimi. Iyi asfalt ubwayo ntabwo ifite ibara cyangwa ibara, ariko yijimye yijimye, mumyaka yashize, hamwe yitwa asfalt y'amabara kubera akamenyero k'isoko. Kugeza ubu, amabuye ya beto ya asifalti yo mu Bushinwa arashobora kugabanywamo amoko abiri yingenzi: ubwoko bwa mbere bwakozwe mugukoresha asifalti ibonerana cyangwa isobanutse neza, hanyuma ikongeramo pigment organic organique kumvange ya asfalt; ubwoko bwa kabiri ni Bukozwe muri sima iboneye cyangwa isobanutse. Hanyuma ikorwa mukuvanga ibikoresho byamabuye yamabara asanzwe hamwe. None ni ibihe bintu biranga asifalt yamabara ya pavement?

Hindura umujyi, utezimbere ibidukikije, kandi werekane imiterere yumujyi. Ikoreshwa cyane mumihanda y'abanyamaguru, ahantu nyaburanga, kare, parike, imihanda nahandi. Yuzuza ibyatsi bibisi bikikije, ibiti, indabyo, nibindi, bityo birimbisha ibidukikije kandi biha abantu imyumvire. Ishimire ubwiza. Ifite umurimo wo gutunganya no kugenzura ibinyabiziga, kandi ikoreshwa cyane cyane gutandukanya ibice byumuhanda ninzira zifite imirimo itandukanye kugirango hongerwe imbaraga zo kumenyekanisha hejuru yumuhanda, ubushobozi bwumuhanda wumuhanda n'umutekano wo mumuhanda. Ifite imikorere myiza yumuhanda. Bitewe nubushyuhe butandukanye nibidukikije byo hanze, ubushyuhe bwacyo buhanitse, kurwanya amazi kwangirika no kuramba nibyiza cyane, kandi ntibigaragara ko byangirika, gukuramo firime ya asfalt, nibindi, kandi bifite amata meza ahuza urwego rwibanze. . Ibara ni ryiza kandi riramba, ntirizimangana, rishobora kwihanganira ubushyuhe bwo hejuru bwa 77 ° C n'ubushyuhe buke bwa -23 ° C, kandi byoroshye kubungabunga. Hamwe nimikorere ikomeye yo kwinjiza amajwi, amapine yimodoka ntashobora gutanga urusaku rukomeye bitewe no guhumeka ikirere iyo azunguruka umuvuduko mwinshi mumuhanda, kandi ashobora no gukurura andi rusaku aturutse hanze. Ifite ubuhanga bukomeye kandi bworoshye, kumva neza ibirenge, bikwiriye kugenda nabasaza, kandi bifite imikorere myiza yo kurwanya kunyerera mugihe cy'itumba.
