Ibikoresho bikoreshwa mu kuvange ya Asfalt birimo umukungugu mwinshi. Iyo ibikoresho bikora, niba umukungugu winjiye mu kirere, bizatera umwanda. Kubwibyo, ibikoresho byo gukuraho umukungugu bigomba gushyirwaho, none gukuraho umukungugu nuburyo nyamukuru. Umutekano nikibazo rusange. Hariho amategeko asanzwe yumutekano asanzwe.

Ntusukure, amavuta cyangwa uhindure ibikoresho byose bya mashini bitasobanuwe byumwihariko mugihe cyo gukora; Zimya imbaraga zikayifunga mbere yo kugenzura cyangwa gukora kugirango witegure impanuka. Kuberako buri kintu gifite umwihariko wacyo. Noneho, ube maso kubyerekeye ibibazo byangiritse umutekano, ibibazo bitari byo hamwe nibindi bitabo. Bose barashobora kuganisha ku mpanuka, gukomeretsa umuntu, kugabanya imikorere yo gukora umusaruro, kandi icy'ingenzi, kubura ubuzima. Kwirinda no gukumira hakiri kare ninzira nziza yo kwirinda impanuka.
Kubungabunga neza kandi neza birashobora gutuma ibikoresho bikora neza no kubigenzura murwego runaka rwanduye; Kubungabunga buri kintu kigomba gukorerwa ukurikije amahame ashinzwe; Gahunda yo kubungabunga hamwe nuburyo bwo gukora neza bugomba gushyirwaho hakurikijwe ubugenzuzi no gusana bigomba gukorwa.
Kuramo ibikorwa kugirango wandike ibisabwa byose no gusana, andika isesengura rya buri kimwe muri buri gice hamwe nibisobanuro byo gusana cyangwa itariki yo gusana; Intambwe ya kabiri nugutanga ubugenzuzi kuri buri gice, kigomba kugenwa ukurikije ubuzima bwa serivisi no kwambara imiterere ya buri kintu.
