AMAKURU

Umusenyi ni urutare rwimeza rugizwe nuduce duto twa sima tumeze nk'umusenyi.Ni ikozwe cyane cyane kuva mu nyanja, ku mucanga no mu biyaga ndetse no ku rugero ruto ruva mu musenyi. ibumba, icyuma, gypsumu, asfalt nibindi bintu bisanzwe.

Grit ifite urukurikirane rwibyiza bidashoboka:

Kongera imbaraga z'ubushyuhe bukabije, kurwanya ubukonje bwinshi no kwinjiza neza;

Guhuza neza kubikoresho byihariye (egconstruction rollers);

Guhuza neza na asfalt na sima morar;

Ibipimo byiza byerekana （kuba hari inshinge n'ibice bya lamelar）;

Iradiyo ikabije cyane no kubungabunga ibidukikije;

Niyo mpamvu hakenewe kunoza ibikoresho byo mumijyi no mumujyi;

Igiciro ni gito, kizwiho kugira ingaruka kubiciro rusange kubaguzi.

Icyiciro cya kaburimbo M400 na M600

M400- Intege nke.

Sandtone yajanjaguwe ifite uburyo bwinshi bwo gusaba-kuva mu gukora no gutunganya beto kugeza ku gishushanyo mbonera. Bitewe nimiterere yumubiri na chimique, ibuye ryihanganira ubukonje kandi

Ibikoresho birwanya ubuhehere hafi ya byose ntibibangamiwe nikirere kandi ntibizashira kubera izuba ryinshi.

Inganda za Shanvim (Jinhua) Co, Ltd zimaze imyaka irenga 20. zifite ubuhanga bwo kwambara no gusiga ibikoresho. Twama tugerageza uko dushoboye kugira ngo dutange serivisi zizewe nyuma yo kugurisha kuri buri mukiriya. Dufite uburyo butandukanye bwibikoresho na serivisi zunganira fasha abakiriya bacu kugera kubyo bagamije gukora muburyo bunoze kandi buhendutse.

Niba ukeneye ibicuruzwa byujuje ubuziranenge kugirango wirukane intego ikomeye, nyamuneka reka tugufashe muburyo bunoze.
