Umukiriya wa Guyana yategetse iyi mikino 10t // h imipira ya bitumen ishonga ibikoresho byacu ku ya 12 Nzeri. Nyuma yiminsi 45 umusaruro mwinshi, ibikoresho byanyuma byabakiriya. Ibikoresho bizoherezwa ku cyambu cy'igihugu cyabakiriya vuba.

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:

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.

Vuba aha, umukiriya wacu wa Buligariya yaguze ibigega 6 byo kubika Asfalt. Ubu ni ubufatanye bwa kabiri hagati yitsinda rya siyarreer hamwe nuyu mukiriya.

Vuba aha, abati ba kera b'itsinda rya CONAGORANDERY bakomeje kugura ibicuruzwa, abakiriya ba Uae bagarutse kumwanya wa gatatu wibikoresho bya Asfalt hamwe nibikoresho bifitanye isano.
