Anigihingwa cya asfaltikoreshwa mugutanga ubushyuhe-buvanze, ubushyuhe-buvanze, hamwe nimbeho ivanze asfalt yo kubaka umuhanda no gufata neza imishinga. Niba ari aigendanwa rya asfaltcyangwa igihingwa gihagaze, inzira yibanze yo gukora irasa.

Intambwe ya 1: Kugaburira Ubukonje

Ingano zitandukanye za agregate zipakirwa mubikonje bikagaburirwa muri sisitemu ukurikije ibipimo bivangwa.

Intambwe ya 2: Kuma no gushyushya

Igiteranyo cyinjira murikumisha ingoma, aho icyotezo cyiza cyane gikuraho ubushuhe kandi gishyushya ibikoresho kubushyuhe bukenewe.

Intambwe ya 3: Kugenzura no gupima

Igiteranyo gishyushye kirasuzumwa kandi gitandukanijwe nubunini. Sisitemu yo gupima yemeza neza neza ubuziranenge bwa asfalt.

Intambwe ya 4: Kuvanga inzira

Igiteranyo, bitumen, na minerval yuzuza bivangwa imbere yivanga kugirango bitange kimwekuvanga asfalt (HMA).

Intambwe ya 5: Kubika no Gutwara

Uruvange rwa asfalt rwuzuye rubikwa muri silo ishyushye cyangwa rushyirwa mu gikamyo kugirango rujyanwe ahazubakwa.

Kuki inzira ari ngombwa?

Byakozwe nezakuvanga asfaltiremeza:

• Ubwiza bwa asfalt
• Umusaruro mwinshi
• Gukoresha lisansi nkeya
• Kugabanya amafaranga yo gukora
• Imikorere yizewe

Umwanzuro

Gusobanukirwauko igihingwa cya asfalt gikoraifasha abashoramari guhitamo ibikoresho byiza no kuzamura umusaruro. Ibimera bigezweho bya asfalt bihuza automatike, neza, ningufu zingirakamaro kugirango dushyigikire imishinga yo kubaka umuhanda.
