Mu myaka yashize, Irani yateje imbere cyane ishoramari ry’ibikorwa remezo no kubaka imishinga y’imihanda hagamijwe guteza imbere ubukungu bwayo, bizatanga amahirwe menshi n’amahirwe meza yo guteza imbere imashini n’ibikoresho by’ubwubatsi by’Ubushinwa. Isosiyete yacu ifite abakiriya beza muri Irani. Uruganda ruvanga asfalt, ibikoresho byuruganda rwa bitumen, ibinyabiziga bifunga ibyuma nibindi bikoresho bya asfalt byakozwe na Sinoroader byakiriwe neza nisoko rya Irani. Imodoka ebyiri zifunga ibicuruzwa byategetswe n’umukozi w’ikigo cya Irani mu ntangiriro za Kanama zarakozwe kandi zirasuzumwa, kandi ziteguye koherezwa igihe icyo ari cyo cyose.

Ikamyo ifunga kashe (aslo yitwa Micro-Surfacing Paver) ni ibikoresho byo gufata neza umuhanda. Nibikoresho bidasanzwe byatejwe imbere buhoro buhoro ukurikije ibikenewe byo gufata neza umuhanda. Ikinyabiziga gifunga kashe cyiswe imodoka yo gufunga ibicuruzwa kubera ko igiteranyo, bitumen emulisile hamwe ninyongeramusaruro zikoreshwa bisa na slurry. Irashobora gusuka imvange iramba ya asfalt ukurikije imiterere yubuso bwa kaburimbo ishaje, kandi igatandukanya ibice hejuru yumuhanda wa kaburimbo amazi n'umwuka kugirango birinde gusaza kwa kaburimbo.

Ikamyo ifunga ibishishwa ni uruvange ruvanze ruvangwa no kuvanga igiteranyo, biti emulisiyumu, amazi hamwe nuwuzuza ukurikije igipimo runaka, ikagikwirakwiza neza hejuru yumuhanda ukurikije uburebure bwagenwe (3-10mm) kugirango habeho guta bitumen. TLC. Ikinyabiziga gifunga ibicuruzwa gishobora gusuka imvange ndende ukurikije imiterere yubuso bwa kaburimbo ishaje, ishobora gufunga neza kaburimbo, gutandukanya ibice hejuru y’amazi n’umwuka, kandi bikarinda kaburimbo gukomeza gusaza. Kuberako igiteranyo, emulisile bitumen ninyongeramusaruro zikoreshwa ni nkibishishwa, byitwa kashe ya kashe. Igicucu ntigishobora gukoreshwa n’amazi, kandi hejuru yumuhanda wasanwe nigituba ntirishobora kunyerera kandi byoroshye ibinyabiziga gutwara.

Sinoroader iherereye muri Xuchang, umujyi w’amateka n’umuco byigihugu. Nibikoresho byubaka umuhanda bihuza R&D, umusaruro, kugurisha, inkunga ya tekiniki, ubwikorezi bwinyanja nubutaka na serivisi nyuma yo kugurisha. Kohereza ibicuruzwa byibuze 30 byinganda zivanze na asfalt, Micro-Surfacing Pavers / Amakamyo ya Seurry Seal hamwe nibindi bikoresho byo kubaka umuhanda buri mwaka, ubu ibikoresho byacu byakwirakwiriye mubihugu birenga 60 kwisi.
