Mune zvimwe zviitiko, rimwe nokurasa?

Mugore chinyakare shanduro nokurasa rinoitwa pasi nzvimbo dzisina kuona kunyange mwero zvinorema kutakura. Kunyanya, tsika rakasikwa mifananidzo yakadaro kuwana coatings kunze kweguta. Uyewo tichibatsirwa zvigadzirwa ichi kuita zvakawanda pedutu basa. Roga, yokuraswa kwemarara kunodikanwa chaiwo rukoko zvivako, saka kunzvimbo vowanda zvaidiwa rokumusoro Dam, siya mugwagwa pemvura iri muchimiro nekuumbanidzwa Asphalt granulate. Nezveshoko kushandiswa kwemashoko sezvo zvokugadzira zvinhu zvinoriumba, anodzvinyirirwa ibwe Somuenzaniso, unogona kuita zvinobudirira abudise rukoko.
