Ibikoresho bya mashini bitwa kubaka umuhanda byitwa imashini zubwubatsi nibikoresho. Mu mashini nyinshi zo kubaka umuhanda n'ibikoresho, tugomba kuvuga ibikoresho byo kuvanga asfalt. Asfalt ni amazi meza. Iyo uvanze, ibikoresho bivanze bifite ibisabwa byinshi. Kuki uhitamo Itsinda rya CENOWHERHERS BAHPHARDS BURUNDU? Kuberako ifite ibiranga bikurikira:

Nk'uko ubushakashatsi bwabanje hamwe n'iperereza ry'amashyirahamwe, kaburimbo ya Asfalt bigira ingaruka ku mahirwe, kwinjiza, okiside, n'ibitero bya asfalt bitoroshye cyane mu biro bya kabiri, bikavamo kaburimbo. Hamwe nisukari ya asfalt, pavement ikuze ishyira ahagaragara. Kaburimbo ya Asfalt yinjira mu cyiciro cyo gusaza kubera gutanyagura no mu kirere, aho amabuye ahuye n'ibice bito kuri kaburimbo.

Bitumen ni umukara kandi watsinze cyane cyangwa igice kinini cya peteroli. Irashobora kuboneka mubitsa amabuye y'agaciro. Imikoreshereze nyamukuru ya asfalt (70%) iri mubwubatsi bwumuhanda, nkagabumwe cyangwa ifatika kuri asfalt beto. Ibindi bikorwa byingenzi biri mubicuruzwa bya asfalt oftaltroof, harimo hejuru yinzu yubushuhe bwo gupima kugirango ushyire hejuru ibisenge.

Mu misaruro ya Asfalt, ubushyuhe butunganya ni ikintu cyingenzi mu mikorere yibihingwa nibiranga kuvanga. Kugirango habeho ubuziranenge bwa kaburimbo, ubushyuhe bugomba gukurikiranwa mugihe cyo kubyara kandi iyo ivanga ishyushye ari ?? yashyizwe ku gikamyo. Kugirango ubushyuhe bugume mu mipaka yagenwe mugihe ibikoresho bitangiwe kuri Mixer, ubushyuhe bukurikiranwa aho ibikoresho bisiga ingoma. Gutwika kugenzurwa ukurikije aya makuru. Niyo mpamvu ibikoresho byo kuvanga Asfalt bikoresha pyrometero kubikoresho bitarisha amakuru hamwe na sisitemu yo kugenzura ubushyuhe.

Uburyo bwubwubatsi bwa kaburimbo yahinduwe ahanini ikubiyemo intambwe zikurikira:

Kubaka ikana inshalt cyuma ryumuhanda ni umushinga urimo intambwe nyinshi ningingo zingenzi. Ibikurikira ni intangiriro irambuye kubikorwa byubwubatsi:
